56 Notes on Lepidopterous Larvce. [zoe 



of prothorax, which instead is longer hairy especially on borders; 

 moreover all the segments (except head) present a pubescent 

 appearance, being covered with the short hairs arising from the 

 spinous tubercles, these hairs usually (in three specimens — not 

 in the faintly humped one) becoming longer on the dorsum along 

 the median row of hump-like transverse ridges. The pubescence 

 in these three specimens (above mentioned) also becomes some- 

 what longer along the sides of the larva. Head not so glabrous, 

 black, but not so polished. Eyes apparently nearly the same. 

 Mandibles apparently nearly the same. Legs and prolegs same; 

 spiracles same, consisting of 9 pairs, on sides of segments 2, and 

 5 to 12, those on II and 12 situated more on dorsum of seg- 

 ments. 



Described from four specimens. Southern N. Mex. General 

 colors noted in life. It had occurred to me that possibly there 

 were two species represented in the above larvae, but their 

 uniform pubescence and the connecting variations between them 

 lead one to consider them as belonging to the same species. 

 Their pubescence seems to point them out at once as distinct 

 from the species on A triplex. 



Mr. W. H. Edwards has treated in a most interesting manner 

 of the special organs of segments 11 and 12 in the larva of 

 Lycaena pseudargiolus (Butt. N. Am. vol. ii. Lycaena ii, iii, 

 pp. 10-16). A figure is« given of the last segments (p. 14), 

 showing these organs. All of the four larvae above described from 

 mesquit show the organs veryjplainly ; the median transverse open- 

 ing on II, and the two tubes on 12 wholly withdrawn inside and 

 showing as a rounded stigma-like organ with many wrinkles 

 radiating from the centre. 



III. LARVA OF OIKETICUS TOWNSENDI (rILEY MSS). 



This species is our common bag-worm in Southern New Mex- 

 ico. Some detailed notes have been published on this species in 

 the Can. E7it., 1892, p. 199, under the name " Thyridopteryx sp." 

 Specimens hadSbeen sent to Dr. Riley, who wrote me too late for 

 insertion in the above-mentioned notes that the insect proved to 

 be a new species of Oiketicus, which he would describe at some 

 future time under the above name. The present seems an ap-
