tellum shining, with strong well-separated punctures ; metathorax basally with 

 strong punctures like those on scutellum, but a triangular area beyond this 

 shining and impunctate ; tegulae fuscous in middle, testaceous at sides; wings 

 dusky, nervures sepia ; b. n. meeting t. m. ; second s. m. extremely broad, 

 receiving first r. n. at about the beginning of its last third ; hind wings with 

 venation normal for the genus; hind basitarsi ordinary, not toothed; abdomen 

 with fine distinct punctures. 



Female. — More robust ; no light face-marks ; clypeus strongly punctured ; 

 labrum with long ochreous hair ; antennse short, flagellum clear fulvous beneath 

 except at base, scopa on hind tibiae and tarsi long and loose, strongly plumose. 

 pale ochreous ; hair on inner side of hind basitarsi ferruginous. 



Habitat. — Guayaquil, one of each sex, the male the type (v. BiicJi- 

 wald; Alfken coll. i8) ; Guayaquil, i female, May-June, 1913 (Brues). 



Closely related to L. pcrcyrcc Holmbg., but the male differs by the 

 longer third antennal joint, the darker tegulse, the redder hair of 

 abdomen, the dark tibise, etc. 



CHALEPOGENUS Holmberg. 

 Tctrapcdia, as generally understood, is certainly composite. T. 

 diz'crsipcs Klug, the type of the genus, has the first recurrent nervure 

 joining the second s. m. before the middle, and the hind spur long 

 pectinate. T. plnmipcs Smith, though very different in color, has the 

 same structural characters. There exists, however, a group of species 

 with simple hind spur, and the first r. n. joining the second s. m. near 

 its end. In Psyche, 1912, p. 57, I described a species of this latter 

 group under Tapinotaspis, remarking that it was certainly not con- 

 generic with the type of Tctrapcdia, but could only go in Tapinotaspis 

 if we altered the definition of that genus. Upon further investiga- 

 tion, I conclude that the proper name for insects of this type is Chalc- 

 pogcnus, the type of which is C. muelleri (Tctrapcdia miicllcri Friese ; 

 Chalcpogcnus inccrtus Holmbg.). Dcsmotetrapcdia Schrottky, 1909, 

 having the same type, is strictly congeneric. My species described in 

 the place just cited will stand as Chalcpogcnus hcathi (Ckll.). The 

 same genus extends into Central America, Chalcpogcnus viocstiis 

 (Tctrapcdia mocsta Cresson) being a typical representative. Other 

 Central American species are C. calcarata (Tctrapcdia calcarata 

 Cress.) and C. mayarum (Tctrapcdia inayanini Ckll.). 



Chalepogenus buchwaldi new species. 



Female. — Length nearly 7 mm. ; black, the wings reddish fuliginous, slightly 

 paler but not at all whitened apically ; hair of labrum and sides of face dull
