THE CANADIAN ENTOMOLOGIST. 197 



thorax narrower than the head, longer than broad, enlarged at the base, 

 flat, a transversal sulcus after the apical third. Legs rather long, dark 

 fuscous, shining; fore legs with the femur, tibia and basal joint of tarsi 

 equally long, compressed, dilated, the tarsal joint thicker, with a longi- 

 tudinal furrow ; the two apical joints short, the last one longer than the 

 preceding ; middle legs not so dark, more brownish, very little dilated, 

 the basal joint of tarsus short, scarcely longer than the two following 

 together ; the whole tarsus very little longer than the tibia ; hind legs 

 with very strong, long, dilated femur ; tibiae shorter, less dilated, com- 

 pressed ; tarsus about as long as tibia, basal joint not dilated, about as 

 long as the two others together ; the second very short ; all claws bent, 

 sharp, much thicker at base, rufous. Abdomen black, villous, shining, 

 one third shorter than the wings ; last dorsal segment polished ; appen- 

 dages black, villous, very long; basal joint thick, straight, apical joint 

 longer, thinner, a little narrowed in the middle. The abdomen is too 

 much shrivelled to make out anything more ; I can not see any asymme- 

 try, at least not of the appendages. Wings about four times longer than 

 broad, smoky black, rugulose, with four narrow white longitudinal lines, 

 the anterior (fifth) wanting ; venation dark fuscous ; sector trifurcate ; 

 about five costals and five transversals in the cell ; in the spaces below 

 some transversals. 



Hab. — Brazil. I have before me two dry specimens ; one from the 

 collection of the late Dr. Schneider in Breslau, Prussia, has only the label 

 Brazil ; it may have belonged to the same lot with Burmeister's types and 

 those in the Berlin Museum, but it has not been compared with them. 

 The other was collected by the late Mr. Appun in A^enezuela ; head and 

 prothorax wanting. 



In my Synops. Embid. p. 221, I had put E. Kliigi Ramb., Neur. p. 

 313, No. 3, with a question mark, to O. riificapilla. In my Syn. of N. 

 Amer. Neur., p. 301, it was given as a separate species. I have never 

 seen the type, which was collected by Delalande in Brazil, and belongs to 

 the Museum in the Jardin des Plantes in Paris. Rambur has apparently 

 omitted to describe the wings. If they had not been present, he would 

 have named the specimen a larva, as in the two other cases. Otherwise 

 his description, which is very detailed for the legs, contains nothing that 

 would not apply to O. ruficapilla ; perhaps his specimen was somewhat 

 darker. 



The specimen from Brazil before me presents in all the wings an inter-
