Family AGARISTID.E. 



ALYPIA MACCULLOCHII Kirby. 



Larva. — Head rounded, bilobed, erect, white, thickly covered with 

 rather large black spots and a few small ones; a 5^ellow shade over 

 vertices of lobes and at bases of antennre. Body cylindrical, normal, 

 noctuiform, joint 12 slightly enlarged dorsally. White with broad 

 diffuse 3^ellow shades subdorsally (tubercle ii) and substigmatally 

 (tubercle v), the former becoming deep orange on the hump on joint 

 12. Tubercles large, black, but round and low, not elevated into 

 cones. Many irregular, confused, crinkled black marks. No white 

 subventral spots whatevei-, the black markings heavy subventrally; 

 venter less heavily marked. Abdominal feet black at the base, flesh 

 colored outwardly; thoracic feet black. Setie long, white. The black 

 markings form a series of broken lines and dots, a heav}", geminate, 

 dorsal line, widened a little posteriorly on the segments and with a 

 narrow median spur projecting lateral!}', more sparsely lined where 

 the yellow color is; sides quite heavily marked; subventral reo'ion 

 strongl}^ marked, especially above the feet. 



Larvae on Cha/nsenerlon angustifolium resting on the backs of the 

 leaves. Found at the Half- Way House above Manltou, July 21. The 

 larvfB entered the earth to pupate in a few days and the lirst imago 

 emerged May 4 the following season. 



Family LASIOCAMPID^. 



MALACOSOMA TIGRIS Dyar.i 



Egg.s. — Laid in a patch half as long as wide reaching halfway or all 

 around a small twig. Elliptical, flattened on two sides, the larger end 

 squarely truncate, rimmed, the nearly circular center raised; small 

 end rounded. Laid erect on the small end. fastened together by gum, 

 but the exposed ends clear of an}- varnish; the mass looks white 

 and the spaces between the eggs are visible. Sordid white, a dark 

 micropylar dot. Surface smooth, slightly shining, scarcely shagreened. 

 Size 1 by 0.6 by 0.5 mm. 



The Qgg masses were found on the lower twigs of the food plant, 

 often very near the ground. Exactly similar e,g^ masses were sent to 

 the Department of Agriculture from Jonesboro, Coryell County, Texas, 

 which hatched on April 5. 2L tigris was then undiscovered and 1 

 could not imagine what these eggs were. A memorandum of the food 

 plant was not sent me and the larvae refused the plants that I offered 

 them. This localit}^ is somewhat distant from the place where I dis- 

 covered the species; how^ever, I insert my notes on the first stage of 

 the Texan larvae, as I believe that they are of the same species.
