LEPTOMERINTHOPHORA. 287 



LEPTOMERINTHOPHORA, Rehn. 

 Leptomerinthophora, Rehn, Proc. Acad. Nat. Sci. Philad. 1905, p. 436. 



This genus seems to be more closely related to Vilerna, Stal, than to any other of 

 the group. It contains several forms, of which L. brevipennis, Rehn, is the type. The 

 species before me all inhabit Costa Rica. They may be recognized by the following 

 brief table : — 



Synopsis of the Species of Leptomerinthophora. 



A 1 . Hind femora dull clay-colour or brunneo-testaceous, either plain or 

 marked with oblique fuscous bands and mottlings. 



b 1 . Femora plain, tinged with green 1. brevipennis, Rehn. 



b 2 . Femora obscurely marked externally with oblique and internally with 



transverse bands ; antennae inconspicuously annulate 4. modesta, sp. n. 



A 2 . Hind femora green or greenish, unadorned, apex testaceous. Antennae 

 pale, annulate. 

 b 1 . Most of face, cheeks below the eyes, and pale lines on pronotum, 

 pleura, and tegmina bright wax-yellow. [East slope near base of 



Mt. Irazu, Costa Rica.] 3. flavovittata, sp. n. 



¥. Most of face, cheeks below the eyes, and pale lines on pronotum, 

 pleura, and tegmina brownish-testaceous. [Pacific slope south- 

 westerly.] 2. smaragdipes, sp. n. 



These insects are to be met with in the tangle of low vegetation that nourishes in 

 somewhat open spaces and along the edges of the denser forests. In habit they are 

 somewhat sluggish, but when disturbed are capable of making long leaps. Their 

 coloration is protective and renders them difficult of detection when at rest among the 

 fallen leaves and low-growing herbage.

This species is not represented among the material at hand, and has not been seen 

 by me. The insect may be rare and rather local in its distribution, since Mr. Carriker, 

 who collected for me in the same region, failed to secure specimens of it. 



2. Leptomerinthophora smaragdipes, sp. n. 



Head as wide as the front edge of the pronotum, with the occiput short, only gently inflated, and provided 

 with a median, though faint, longitudinal carina which is most apparent anteriorly. Eyes large and 



this insect is nocturnal in its habits and that the pearly granules or follicules, which adorn the metapleura 

 and hind femora, are phosphorescent. Should this be true, it would oertainly be interesting in the extreme. 

 The insect, on this account, may prove to be much more widely distributed and should reach the Isthmus 

 of Panama.
