Figs. 1–3  
 Description. Holotype male: Narrowly ovate, narrower behind than in front, inconspicuously setose and moderately shining; head and pronotum black with strong pale blue reflections, scutellum black, elytra dark blue with violaceous reflections; beneath black; length 2.2 mm, width 1.35 mm (Fig. 1).   
Head rounded-trapezoidal with slight medial depression from above, eyes flat, barely visible from above; from front, medial depression linear and moderately strong from top to middle of eyes; surface sparsely, finely ocellate punctate and shining above, at top of eyes grading to coarsely shagreened on front with indistinct point punctures; large pore at inner margin of eye joined by shallow groove above narrow ridge above antennal insertions.  
Pronotum moderately convex, 3-1/2 times as wide as long at middle, apex 1/2 as wide as base; sides nearly straight on basal 1/2 then slightly rounded to apical angles; anterior margin very shallowly emarginate; base broadly emarginate anterior to scutellum, more narrowly and less strongly so anterior to elytral lobes and humeri; posterior angles acute and slightly projecting beyond humeral angles of elytra; surface slightly obliquely depressed toward sides anterior to elytral humeri; disk glabrous, strongly shining, sparsely, finely ocellate punctate. Scutellum 1/4 wider than long, anterior margin strongly rounded, surface polished.  
Elytra at base slightly narrower than pronotum, widest at basal 1/3; humeral angles narrowly obtusely rounded; sides weakly arcuately rounded to tips which are narrowly, separately rounded; each elytron with slight depression at base interior to humeri, and deeper depression behind humerus along lateral margin from humeral angle to before middle; oblique shallow depressions from suture to elytral margins near tips creating oval raised areas along suture anterior to apices; surface irregularly, somewhat coarsely punctate, some punctures coalescing into transverse rugae on apical 1/2, setae in punctures minute.  
Abdomen beneath faintly reticulately shagreened with few inconspicuous setae; last sternum with broadly acute medial triangular process and a few longer setae at apex. Prosternum smooth, barely emarginate in front; prosternal process broad, sides slightly wider behind coxal cavities, then narrowing angulately and transverse at apex. Genitalia as in Figure 2.  
Allotype female: Length 2.4 mm. As male but apex of terminal ventral abdominal sternum with two sets of four teeth separated by V-shaped notch; of four teeth, innermost very small and broadly triangular, middle two longer and acute, outermost acute and much smaller (Fig. 3).

 Additional Specimen. Texas: Cameron Co., Brownsville, 01.06.1939, D.J. and J.N. Knull (1, FMNH).   
 Hosts. Adults have been collected on species of Desmodium (‘‘ obtusum ’’), Lespedeza (‘‘ capitata ’’), and Psoralea sp. (all Fabaceae).   
 Discussion. Males vary in size from 2.05 to 2.95 mm in length (mean ¼ 2.46 mm for 134 specimens); females vary from 1.90 to 2.95 mm in length (mean ¼ 2.53 mm for 93 specimens). This species is named in honor of the late George Vogt for his extensive studies of the genus Pachyschelus and his generous assistance with my research. The specimen from Texas seems to belong to this species, but there is an absence of material between its locality and the nearest localities in Florida.
