leg-plate, consisting of scattered hairs, not a defined tubercle. Crochets 

 of abdominal feet few. on the inner two-thirds of the planta only. 

 Shields not cornified, concolorous. 



Stage VI. Head whitish with a bioad band of confluent black-brown 

 inottlings on the face of each lobe, narrowing below, furcate at the ver 

 tex; clypeus moderate, depressed at apex; mouth brown, ocelli black; 

 width 1.4 mm. Rounded, scarcely bilobed, lower than joint 2 but not 

 retracted. Body cylindrical, a little flattened, thick and squarish ; feet 

 normal, rather slender. Dorsum sordid brown, edged by a black lateral 

 band (tubercle iii) somewhat diffuse above; joint 2 dorsally and sub- 

 venter whitish, distinctly whitened about the spiracles. Tubercles i to vi 

 black, rather large, a little elevated, iii the largest; vi double the whole 

 length, the pair united on joints 2 to 6, separate on 7 to u, approximate 

 on 12; iv and v in line, united on joints 5 and 6, nearly so on 7, separate 

 on 8 to 12, more widely so posteriorly [Stages v and vi not described 

 from the same larvaj. Setae moderate, dusky. In this stage the larvae 

 go down off of the leaves and hide, in the daytime, feeding only at night, 

 not resting on the backs of the leaves as they did before. Later the 

 dorsum darkens to various shades of dead-leaf brown shading to black at 

 the edges subdorsally. Subventral region white, divided by a narrow 

 sordid line. 



Pupation at the surface of the ground, the small brown pupa 

 resembling that of Callidapteryx dryopterata. Food plant 

 Lonicera dioica, named for me by Mr. C. L. Pollard. 



A discussion then followed, participated in by Messrs. Ash- 

 mead, Gill and Heidemann, upon the systematic value of 

 characters furnished by the eggs of insects. 



Mr. Ashmead called attention to a valuable paper published 

 by Mr. C. T. Brues in the American Naturalist for May, in 

 which were descriptions of several new genera of flies, some 

 new beetles and a curious new genus of Proctotrypids, all taken 

 in connection with studies on the nests of Eciton. 



Mr. Marlatt recorded some observations made by Mr. 

 Kotinsky and himself on the feeding habits of certain predaceous 

 insects hitherto considered as beneficial, but which may have to 

 be classed nither as injurious species. These observations were 

 made in connection with the breeding experiments and studies of 

 the imported Asiatic lady beetle (Chilocorus similis). In one 

 of the outdoor breeding cages the larvae of Adalia bipunctata, 

 a Coccinellid beetle, which commonly feeds upon aphids, oc-
