broadening at the humeral angle; in length the elytra are fully twice 

 that of the pronotum and together are considerably broader than it, 

 posteriorly truncate. Wings brown on the inner half, yellowish on 

 the outer, projecting beyond the tips of the elytra a distance equal to 

 about two-thirds the length of the latter, rounded posteriorly. Legs 

 brownish or black, the femora \&vy stout. Abdomen convex, short, 

 distinctly broader mesially, lateral folds scarcely in evidence, the 

 terminal segment broadl}' transverse; forceps of the male about as 

 long as the abdomen, triangular basally, apically cylindrical, curved 

 moderately inward basally widely separated and armed on the inner 

 margin with some minute teeth; of the female slender, somewhat 

 shorter and straighter, the denticles in the inner margin a little larger, 

 basally less widely separated. Pygidium of the male very broad, 

 somewhat longer than broad and apically rounded, entire. 



Lengtlc. — Body, without forceps, male, 3.5— i mm., female, 8.5 mm.; 

 forceps, male, 1.25-1.5 mm., female, 1 mm.

Except for size this species bears a superficial resemblance to 

 Spongophora pygmaea as figured by Bormans.'' The p3'gidium of the 

 male will serve to separate it from Lahia hilhieata Scudder, to which 

 it bears a somewhat close resemblance.

One female, Livingston, Guatemala, May 5. 



Description. — General color yellowish brown, the basal two seg- 

 ments of the antennoe lighter, beyond infuscated, the lateral margins 

 of the pronotum and elj'tra and the legs yellow. The elytra show the 

 yellow color mostl}" at the humeral angles, from where it shades ofi' to 

 brownish posteriorly. The inner margins of the projecting portions 

 of the wings show a trace of lighter yellow. Eyes black. 



Head convex, broader than the pronotum; antennae with eighteen 

 segments; ma}^ be more as some of the terminal ones may be missing; 

 the third segment is about as long as the first, three times as long as 

 the second, being about three times as long as it is wide. Pronotum 

 about as long as wide, posteriorly semicircularl}^ rounded, mesially 

 transversally depressed on the disk. Elytra three times as long as 

 broad, together considerably broader than the pronotum, pos.teriorl}^ 

 truncate; wings projecting a distance equal to about one-third the 

 length of the elytra, posteriorly narrowl}' rounded. Legs short and 

 stout, the femora thick, second tarsal joint small and simple, the third 

 liut little hairy beneath, and the claws have a small pad between them. 

 Abdomen without lateral folds, convex, broad, mesially somewhat 

 broadened, the last dorsal segment somewhat transverse, dorsally
