2. Labia insularis, new species. 



A medium-sized, almost naked, smooth-bodied insect with from 14- to 16-jointed 

 antennae, and in which the wing-sheaths are "largely testaceous in the center 

 basally. Basal joint of antennae and legs pale testaceous, the latter somewhat in- 

 fuscated on the femora mesially and tibia; basally. The labium, together with labial 

 and maxillary palpi, also somewhat pale-colored. Head dull black, the eyes large 

 and prominent, rather coarsely granulate. Pronotum about as broad as long, the 

 sides gently bowed ; dull black, becoming brownish on the thinner lateral edges. 

 Tegmina brown with a small testaceous longitudinal shoulder streak, about twice as 

 long as their greatest width, their apices obliquely docked, the truncation gently con- 

 cave. Wing-sheaths moderately large, reaching to the middle of third abdominal 

 segment. Abdomen with the surface polished and only delicately punctate, the sides 

 tun vex, broadest about the middle ; the disk above dark mahogany brown, the base, 

 apex and sides much darker, nearly or quite black ; lower side testaceous basally be- 

 coming ferruginous apically. .Forceps moderately stout, nearly straight and provided 

 internally basally with a short flattened plate or projection the edges of which touch, 

 beyond irregularly crenulate, scarcely toothed, the apices gently crossed. 



Length of body 9 (?), 8.5 mm ; of forceps, 1.85 mm. 



Habitat. — Island of Trinidad, West Indies, H. D. Chipman, 

 collector. 



In this insect the last dorsal segment of the abdomen is a trifle more 

 than three and one half times as broad as long, coarsely punctulate, 

 the sides gently rounded and converging posteriorly, the hind edge 

 straight ; middle of posterior portion lowered and provided with a 

 central shallow depression. 



3. Labia modesta, new species. 



Very similar in general appearance to the preceding but differing from it in its 

 somewhat smaller size, slightly more hairy body, the fewer antennal joints ( 13-14), 

 the absence of the testaceous shoulder stripes on the tegmina, the smaller basal light 

 spots of wing .sheaths which in the present form are lateral rather than central — 

 there being no border of the dark color externally as in L. insularis. Here the thin 

 lateral edges of the gradually broadening pronotum are transparent. The disk of 

 dorsal segments 4, 5, and 6 are brownish testaceous. Lower side along with legs 

 pale testaceous, the latter, with the femora above strongly infuscated. Last dorsal 

 segment smooth, about twice as wide as long, narrowing behind, the middle triangu- 

 larly depressed between centers of bases of the two prongs of forceps and provided 

 with a series of small, round, wart-like raised points. Forceps with their inner edges 

 not laminate, not quite touching basally, evenly tapering, carinate above, crenulate 

 on inner edge, the points crossing. 



Length of body, d\ 7 mm.; of forceps, 1.6 mm.
