130 ENTOMOLOGICAL NEWS. [March, '09 



eral longitudinal black dashes and a central short one and two 

 small lateral black spots on the top of the head. The true legs 

 dark brown, so also the pro-legs. The under side of the body 

 cross lined with black, and white as above, but paler. 



The ventral roundish or quadrangular central row of spots 

 black, but not intensely so. Little change in the larva from 

 hatching to maturity in color and markings. The cross lines 

 of white, the red-brown spots and the broad white under-spir- 

 acular band are the characteristic markings. 



On April 27th I got 14 larva of illecta on low honey locust 

 sprouts in a cow pasture across the street from where I live. 

 These were all small and apparently moulting the third time. 

 They lie close to the twig, usually a dead one, if such is on the 

 bush, or on a bare twig, sometimes two or three quite close 

 together. Very small larvae, probably just after the second 

 moult, often lie along the side of a thorn and are difficult to 

 see. A shriveled dead branchlet is a favorite place for these 

 young larvae. I have noticed the same preference for a dead 

 twig in the young larvae of both C. piatrix and C. cara. 



On April 28th I found 30 more larvae of C, illecta and 101 

 on May 2d. Also one innubcns larva on the latter date. May 

 Qth, 25 larva of C. illecta. 



A full-grown larva of illecta is two and a half inches long. 

 The longitudinal subspiracular band is pearly white. The cross 

 lines of black and white are seven or eight each to the segment. 

 The row of brick-red spots along the spiracles shows strongly 

 against the pearly white band below. Another more prominent 

 subdorsal row of red spots. The end segment of the true legs 

 is black. The pro-legs are striped crosswise. The ventral black 

 spots are large and the ones between the pro-legs the largest. 



The first illecta larva began to spin its cocoon on the 5th of 

 May and pupated on the 8th. The first larva of innubcns pu- 

 pated May the 2Oth. 



The chrysalis of illecta is from one and one-half to one and 

 three-quarters inches long, deep red-brown and covered with 

 a whitish prunescence that makes the pupa look black beneath 

 the bloom. The larva spins a thin cocoon inside leaves and 

 twigs, more often several inches above the bottom of the 

 breeding jar than in the paper on the bottom.
