This species has been assigned to the genera Calolampra and 

 Audreia, due mainly to the fact that the type female had short 

 truncate tegmina. Though this is true for the female sex, the male 

 before us is seen to have fully developed organs of flight, and shows 

 no characters which would warrant its being placed other than in 

 the genus Epilampra. The sexual diversity here shown is seen to 

 be in a way intermediate between that found in E. jorgenseni 

 (Rehn)i°^and the usual condition in the genus in which the sexes agree 

 closely. 



The female before us agrees closely with Saussure's figure,"" ex- 

 cept in being more reddish, the ground coloration of pronotum and 

 tegmina being ochraceous-buff, tinged with ochraceous-tawny. 



The male shows the correctness of the sex association particularly 

 in many of the delicate features of color-pattern. As it had not 

 been previously recognized, we give the following data as to the 

 coloration of this sex. 



Head light ochraceous-buff, occiput with four irregular, vertical, 

 linear suffusions of blackish brown, below these a patch as long as 

 wide, of blackish brown. "^ Antennae ochi'aceous-buff". Pronotum 

 light ochraceous-buff, with very many microscopic dots of proiits 

 brown, numerous larger though minute dots and a delicate, inter- 

 rupted lyrate discal pattern of blackish brown. Tegmina trans- 

 parent light ochraceous-buff, with numerous minute dots (which 

 become smaller distad) and a few flecks of blackish brown, humeral 

 trunk blackish brown to nearly opposite apex of anal field. Limbs 

 light ochraceous-buff; femora margined dorsad with blackish brown, 

 a narrow medio-longitudinal weak suffusion on the cephalic face, 

 both faces with a heavy blackish brown suffusion disto-ventrad ; 

 tibiae dark brown in entire ventral half; distal portions of tarsal 

 joints suffused with dark brown. 



In the female the abdomen has the caudal margins of the tergites 

 regularly marked with small longitudinal patches of blackish brown, 

 which do not project."'^

"^ In the female this patch is more extensive, fusing with the occipital lines 

 dorsad. 



"^ Saussure describes these as "saiUies", this may be in error, as our specimens 

 agrees with the description very closely in all other respects. Many species of the 

 genus have longitudinal projections in place of the markings shown by the ex- 

 ample before us.
