Copiocera austera Gerstaecker 



1889. Copiocera austera Gerstaecker, Mitth. Naturwissen. Ver. Neu-Vor- 

 pomm. und Riigen, Greifswald, xx, p. 36. [Iquitos, Peru.] 



Madeira-Mamore Railroad Camp 41, Rio Madeira. (Mann 

 and Baker.) One female. 



This specimen agrees with the description excepting in the 

 absence of bluish from the base of the wing. As the individual 

 has been in a liquid preservative, has the usual position of the 

 bluish area pale, and we have material of erythrogastra in the same 

 series with bluish removed from the same region by the preserva- 

 tive, we can safely assume this has happened in the present speci- 

 men. 



Walker's nigricans,^^ from Nauta, is either very close to or 

 identical with austera. 

 Coscineuta sordida new species 



A dull colored species, which differs from C. coxalis in the more 

 shallowly impressed transverse sulci of the pronotum, the pro- 

 portionately shorter cephalic and median femora, the absence of 

 red from the coxae, the ochraceous wash on the strumosities of 

 the head, pronotum and pleura, and other color features. From 

 vire7is the new species differs in the deep glaucous caudal tibiae, 

 the differently colored caudal tarsi, and numerous other color 

 features. From cicatricosa the new form differs in the deeper 

 general coloration and the color pattern of the caudal femora. 

 Unfortunately, so little in the way of structural characters are 

 given in the descriptions of virens and cicatricosa, we have to 

 resort to color differences as diagnostic. Bruner's olivacea is a 

 much smaller insect and appears to be so different as to require 

 no comparison. 



Type. — 9 ; Peixe Boi, east of Para, State of Para, Brazil. 

 November to December, 1907. (H. B. Merrill.) [Acad. Nat. 

 Sci. Phila., Type no. 5313.] 



Size rather large; form robust; surface of head, pronotum and pleura rugu- 

 lose to rugoso-cicatricose, of the venter and abdomen glabrous to glabroso- 

 punctulate. Head no wider than the cephalic section of the pronotum : occi- 

 put gently rounded, gently descending to the interocular space, ruguloso- 

 punctulate; interocular space hardly as wide as the frontal costa at the infra- 

 ocellar constriction, weakly sulcate: fastigium short, strongly transverse, the 

 disk deeply rugulos()-j)unctate: fastigio-facial angle rather narrowly rounded 

 when seen from the side, the face slightly retreating from between the antennal
