rn the present article additional speciesof the subgenusfhylidorea are discussed. The majority of the specieswere collected
in New York State by Mr. Howard Notman and the writer.
Others were included in the very rich collectionsof professorRogers. My sincerethanks are extendedto Mr. Notman and professor Rogers for the privilege of examining this material. Except where stated to the contrarv, the types of the novelties arepreservedin the writer's collection.

Pronotum a'd 'resonotum much darker corored, deepbrown medially, a little paler laterally, the median area
sparsely pruinose. Legs with the femora yellow, the tipsrather broadly infuscated; tibiae obscurevellow, the tips nairgwly darkened; basal tarsal segmentsobs.rr.'yellow, theirtips_narrowly _darkened;terminal tarsal segmenisuniformly
dark brown. Wings with a yellowish tinge, the costal region
clearer yellow; stigma brorvn; wing apex and a broad sEamalong ryin Cryinfu_med;a very narrow brown seamalong thecord. Venation: Cell R, strongly narrowed at proximal-end,vein R, being strongly sinuous. Abdomen obscure yellow,
with a dark brown subterminal ring, including segmeniseightand nine, together with a caudal triangle on tergite sevEn.
Male hypopygium with the very elongate aedeagui and subtending gonapophysesof I-. adwsta. Ninth tergite having thegaldaf margin with a broad v-shaped notch, tfie large laterallobeshaving the lateral anglesobtuse. Simple gonappphyses

L. (P.'1 luteola is allied to 1.. (P.) consimilis Dietz, differing in
the coloration of the wings and details of structure of the malehypopygium.
The type-serieswas taken by Mrs. Alexander and the writer inan lri.s swamp in the southern Adirondacks Mountains. A cold
stream flows through an upland pasture, spreading out in thenearby hollows, which are partly filled with Sphagmt,m. The
dominant floral element in the swamp is lris, from which many of
the crane-flies were swept. Others were found resting on thelimbs of spruce and balsam along the margins of the swamp.
Only three males of this handsome specieswere found after a detailed search. Associated crane-fliesin this swamp were: Geranomyia rostrata (Say), Helhrs fl,avipes (Macq.), Pseudolimnophila inornata (O. S.), Linonophila macrocera (Say), Tricyph,onainconstans (O. S.) , Erioptera vespertina O. 5., E. septentrionis O. S., E. needltam.iAlex., and Bittacomorpl,t,aclaaipes(Fabr.).
