for over 24 hours. After all these hardships the larvae were 

 lively, and were now taken indoors, but in a few days most of 

 the number died. A small number survived, which pupated, 

 and by December gth i S and i 9 issued ; after being per- 

 fectly dried up in a bucket for one week 15 larvae were found 

 dead, and from 7 pupae in the same condition issued 3 and 

 4 9 on December 16 and 17, 1905. The same is practically 

 true of another generation of a different variety of the same 

 species, which was allowed to go through the same process at 

 the time. 



The last larvae from masses of October 12, 1904, died Febru- 

 ary 14, 1905. The last larvae and pupa, which died and were 

 from the season of 1905, were from eggs deposited October 

 9th in the evening, and hatched October i4th, died March 10, 

 1906 ; this extends the period of prolonged larval existence to 

 almost 5 months. This is not only a feature in winter, but 

 may occur in regular season, when, from want of food, larval 

 life may be extended 4 or six weeks and over. 



Some of the species associated with C.pipiens in rain barrels 

 of the yards in question were C. rcstuans Theo., C. territans 

 Walk., C. salinarius Coq. and Anopheles punctipennis Say. 



Observations of extremely interesting character, with refer- 

 ence to larvae and adults, is a record of 50 egg masses of 

 Culex pipiens, including the study of antecedents and progeny. 

 The total number of eggs was 15,056, which, under various 

 conditions, produced 7959 adults, of which 3984 were males 

 and 3975 were females.

A New Cantharis. 



BY HENRY SKINNER. 



Cantharis pilsbryi n. sp Black, shining, head with a red spot in the 

 centre ; sides of thorax red. Head convex and shining, with but few 

 punctures, hind angles obtuse. Thorax nearly round, slightly convex, 

 with few punctures. Elytra moderately robust, black, feebly shining. 

 This species is of the same size as deserticola, and the elytra have practi- 

 cally the same character of reticulation. The red spot in the centre of 

 the head and the red sides of the thorax distinguish it from the other spe- 

 cies. Length 22 mm. 



Described from five specimens taken by Prof. H. A. Pilsbry 

 at High Bridge, Pecos River, Texas, April 27th.
