(Figs. 2g, 3g, 4g, 5g, 6f, 7f, 8f, 9f; Plate II-F and III-F). Callidea purpurea Westwood, 1837: 15; Stal, 1868: 10
Diagnosis: Body metallic green to blue, head devoid of any marking, lateral pronotal angles acute, 1 st pair of conjunctival appendages bifurcated.
Colour: Dorsally metallic green with black spots over pronotum and scutellum; head, pronotum, scutellum, and sternum metallic green; first antennal segment, labium, coxae, trochanters, femora (except apices) tibiae and abdomen ochraceous, rest of antennal segments, apices of femora and tibiae metallic green or violaceous blue; small black punctures over pronotum and scutellum
Head: (Fig. 2g) declivent, lateral margins deeply sinuated before eyes; tylus surpasses jugal lobes, breadth (4.05±0.13) 1.2x to length (3.31±0.21), preocular distance (1.51±0.07) 2x to postocular (0.74±0.09); eyes protruded laterally, ocelli located near to eyes than to each other; interocular distance (2.53±0.13) 2x to interocellar (1.25±0.1).
Antennae: Five segmented; I antennal segment (1.18±0.91) never extended beyond apex of head; II (0.44±0.05) and only 0.4x to I; III 5.8x to II; IV longest amongst all and 1.4x to III; V (2.86±0.27) 0.9x to IV; total antennal length 10.13±1.27.
Labium: four segmented; I labial segment smallest (1.09±0.06); II longest (2.26±0.11) and almost 2x to I while III (1.92±0.14) and IV (1.7±0.13) 1.7x and 1.6x, respectively to I segment; total labial length 6.97±0.45 and extended upto II abdominal segment.
Pronotum: (Fig. 3g) convexed, more towards base, anterior margin slightly sinuated, lateral margins straight, breadth at lateral angles (9.82±0.33) 2.36x to anterior pronotal angles (4.15±0.24), and length at middle 4.16±0.24, lateral pronotal angles obtuse; five black spots over surface, two at antero-lateral portion, and two at the posterior end while one at middle but more towards the posterior margin.
Scutellum: (Fig. 4g) slightly convexed at base, anterior margin convex while apical end truncated, covers whole of the abdomen, length (10.6±0.5) 1.2x to breadth (8.95±0.6), seven black spots, six round located towards lateral side in pair while oblong spot and placed at middle near to base.
Legs: with fore, middle and hind femora 3.62 ± 0.24, 4.02±0.31 and 5.53± 0.35, respectively while fore, middle and hind tibiae 3.96± 0.25, 4.01± 0.21 and 5.42± 0.35, respectively; small hairs distributed all over the legs.
External efferent system of metathoracic scent gland: (Fig. 5g) with ostiole small, sunken, peritreme transverse, elevated upward, slightly grooved throughout the length; evaporatorium extended to mesothoracic region, surface is divided into two colour zone i.e., black and yellow, black surface sulcated with fine punctations while yellow surface is smooth.
Abdomen: ventrally convexed; breadth (8.09 ± 0.9) 1.1x to length slightly (7.34±0.45), a black round spot on each ventro-lateral sides, small punctures towards lateral margins but medially it is smooth, arrangement of spiracles and trichobothria same as other species of this genus.
Male genitalia having pygophore (Fig. 6f) with dorso-posterior angle round, inner margin invaginated on its lateral and posterior side, strigils present in patches on dorsal surface.
Aedeagus: (Fig. 7f) with theca distally broad, I pair of conjunctival appendage sclerotized and apically cleft or bifurcated, II pair semisclerotized, anteriorly sclerotized and spinose; 3 rd sclerotized and apically tapered, vesica completely sclerotized, apically notched before gonopore.
Paramere: (Fig. 8f) sickle shaped, stem broad, blade curved and strongly sclerotized, small setae at the base of blade.

Comments: allied to C. pulchellus but externally different in having spots over pronotum and the arrangement of the setal patches over pygophore. The present study focused on its morphological characters, morphometry, male and female genitalia over the earlier study which was restricted to external features only.
