138 ENTOMOLOGICAL NEWS. [April, 



What I take to be the male of this remarkable insect is a spe- 

 cies bright fulvous in color, with the inner margins of the secon- 

 daries and the base of the primaries clouded with fuliginous. 

 The expanse of the wings in the male is somewhat less than four 

 inches. I cannot be certain of my reference of the male before 

 me to the female, but it is the largest male in the genus, and in 

 color comes sufficiently near to the female, of which I possess 

 two tine examples, one of them ex-larva. The caterpillar produ- 

 cing this huge moth, the body of which in the case of the female 

 exceeds in size that of any other of the African Saturniidae known 

 to me, is densely covered with short spines, which are extremely 

 sharp and highly venomous. I was so unfortunate as to incau- 

 tiously handle the cocoon, which is represented in the plate, and 

 to receive some thrusts from the spines with which it is densely 

 covered. The result was severe inflammation, a single point of 

 contact becoming the centre of an inflamed spot as large as a 

 silver dollar in diameter. This venomous property of the spines 

 is persistent, though nearly five years have elapsed since the 

 specimens came into my hands. The moth emerged on April 

 27, 1887.
