SYNOPSIS OF THE ORTHOPTERA OF WESTERN EUROPE. 287 



Now this description, made quite independently, agrees almost 

 absolutel)'^ with Dr. Wood's description of the larva of ( '. caespititiella 

 [Knt. Mo. McKj., 1892, p. 170, etc.), the only differences bemg (1) 

 no spiracular plate on the metathorax, and (2) a distinct black 

 dorsal plate on the anal segment, in my larva. He particularly 

 says that ('. caespititiella feeds up in the autumn, and retires to 

 some fence, trunk, etc., away from the rush, to spin up before 

 the winter. But in the species under consideration the larvae 

 were quite small, and the cases were exactly like the rush cases 

 one meets with in the early autumn, on the fresh recently formed 

 rush seeds. As regards C. (jlaiicicolella, Dr. Wood is careful to 

 point out that the 3rd thoracic segment possesses two ill-developed 

 dorsal plates of which in C. caespititiella there are no trace. 

 Again, he says, that in the former species the spiracular plates on the 

 Brd thoracic segment are conspicuous, whereas in the latter they are 

 unusually small. Furthermore in C. (jlaucicolella larva there is no 

 trace of a black dorsal plate on the anal segment, while ('. caespititiella 

 distinctly possesses one. Thus my larva agreed generally with Dr. 

 Wood's description of ( '. caespititiella, but in its life-history, hybernating 

 on the rush while very small, and feeding up in the spring, it agreed 

 exactly with C. r/laiicicolella. As I failed to breed the imagines 

 there is no further evidence to indicate which species I really 

 had in the larval stage. But as I wished to meet with true 

 ('. <ilancicolella I asked Dr. Chapman if he would write to Dr. 

 Wood, and get him to send me larvfe of the species. This he most 

 obligingly did, and to Dr. Wood I am indebted for larv* of two or three 

 species previously unknown to me. However, C.iilaucicolella was destined 

 to avoid me again, for although Dr. Wood more than once visited the 

 particular locality from which he obtained the larvfe of it, he was 

 unsuccessful. It is true he sent me a few cases, which he thought 

 might possibly be those of this species, yet, upon examination of the 

 larvfe, not one agreed with the careful description given in the Knt. 

 ]\l(i. Ma;/., all were undoubtedly larva? of (/. caespititiella. Mr. Eustace 

 Bankes, who was so successful in obtaining C. (jlaucicolella, and who so 

 carefully followed and substantiated Dr. Wood in his investigation of 

 these obscure, but interesting, species, has just recently obtained for 

 me a number of rush-feeding larvte from his particular locality. Thus, 

 by next spring, I hope to know both Coleopltora caesj^ititiella and 

 C. (/lancicolella, but at the present moment I feel completely in the 

 dark about them. The real object of this note is to enlist the help of 

 other lepidopterists in sending me rush-feeding cases so that I may 

 examine larvie from various localities and get detailed life-histories of 

 these closely allied species.

Subfam. 2 : Eremobiin^e. 



This subfamily contains a few stout species allied to the Oedinopinae. 

 There are but two genera in Western Europe.
