spotted. Spiracles black ringed. Tubercles black", luiimte; setae 

 rather long-. 



Stage VII. — Head subspherical, large, a little elongate, thick, and 

 free from joint 2, not bilobed; clypeus low, narrowly triangular; fifth 

 ocellus close below antenna, large. Broadly white over clypeus and 

 median suture, this color a little more than covering the paraclvpeal 

 pieces and reaching the antenna?, with a faint, double, reddish line in 

 the cl3'peus and another on the paraclvpeal suture. Sides whitish, 

 with many mottled brown lines extending upward, parallel to each 

 other, to the occiput, joining the lines on the body. There are about 

 eighteen on each lobe, each obscurely geminate, mottled with pale 

 dots; on the inner half of each lobe the lines are washed and connected 

 by olivaceous. Clypeal and paraclypeal tubercles black, the others 

 blackish ringed. Width 3 to 3.4 mm. Body slender, uniform; 

 abdominal feet on joints 9, 10, and 13; smooth, nearl}^ cylindrical. 

 Yellowish white, with many brown or black geminate, mottled lines. 

 Dorsal line red-brown, double, in a clear space of the ground color; 

 subdorsal of six black lines with a large black patch in the incisure of 

 joints 6 and 6; four lateral reddish lines; a nearly black suprastigmatal 

 pair; a reddish stigmatal and substigmatal pair; six irregular and 

 broken sub ventral lines, black, inclosed by a dark shade, forming a 

 dark subventral band; next a reddish, then blackish, then two reddish, 

 and finally a broader, nearly black, medio-ventral band. No shields; 

 feet pale, marked with mottled lines. Spiracles black rimmed. 

 Tubercles and seta? small, black; tubercle iv of joint 5 a little above 

 the middle of the spiracle, on joints 6 to 10 between the middle and 

 lower corner, on joint 11 opposite the lower edge, on joint 1'2 like- 

 wise, but the spiracle is one line higher than on joint 11. When dis- 

 turbed, the larva curls up in a curious shape and is quiet, the black 

 marks, ordinarily concealed in the incisure, exposed. Cocoon an 

 elliptical silky net in grass. 



Food plants. — Species of grass. My larvai were fed on Cenchrus sp. 

 Larvae from Palm Beach, Florida, from eggs ' laid 1)V a captured 

 female moth. The species seems to ])reed continuously. 



CHYTOLITA MORBIDALIS Guenee. 



The mature larva has been described by Mr. C/oquillett. ^ His 

 description coincides with my observations, but his statements about 

 the habits are somewhat diverse. He gives as food plants certain fresh 

 leaves, whereas my larvie fed entireh^ on dead and dry oak leaves. 

 However, after hibernation a few of them nibliled at grass and dan- 

 delion, so that it is proba))le that they may eat fresh leaves in the 

 spring. The two dates given — April 1-May T) and June 1-July 20 —
