[Qb'] 92. Omophron Sayi, Kivuy. — Taken by Dr. Bigsby in Canada. 

 Length of body 3? lines. 



Ths species seems intermediate between 0. limbatum and 0. labiatum. 

 From the former it differs in having a much fainter tint of green on the 

 darker parts of the body j in its black prothorax with silvery sides as well as 

 margin. From the latter in having the lateral furrows as deep and distinctly 

 punctured as those of the disk ; and, instead of two reddish spots near the 

 base of the elytra, having two angulato-undulated bands, one near the base 

 and the other beyond the middle, and the tips testaceous; all connected by 

 the margin of the same colour. It seems to have escaped the describers of 

 0. limbatum that the upper-lip and lateral margin of the prothorax and 

 elytra are likewise silvery, though not so conspicuously as in 0. labiatum 

 and Sail. 



The sculpture of the elytra in this genus, as well as in Caloaoma, differs 

 from that of the other terrestrial predaceous beetles in having more than nine 

 furrows, which appears to be the typical number in the section. [Synony- 

 mous with 0. Americanum, Dej.; taken in many parts of Canada.]

LEPIDOPTEIIOUS LAKV^E FIGHTING; 

 AND TENACITY OF LIFE IN" LARVA OF CLISIOCAMPA SILVATICA. 



By HENRY L. JIOODY, Malden, Mass. 



On returning from a collecting tour, one day in last June, I emptied my 

 larvae box, putting in a collar box for a short time a larva of C. Sllvatica, 

 one of the Geometrid and one other Lepidopterous larva : the two last I could 

 not identify, but they were all Lepidopterous. I did noi open the box until 

 three or four hours afterwards, when 1 found a decided change in the appear- 

 ance of my larvae. The C. Sihatica larva was bitten entirely apart, the 

 head and three first segments being in one piece, the three last abdominal 

 segments in another ; the remaining segments were in an indistinguishable 

 mass on the bottom of the box. The geometrid larva was in almost as bad 

 condition, but was not bitten apart; the third was uninjured. 



I have always supposed Lepidopterous larvae incapable of seriously injur- 

 ing each other, and have never heard or read of their doing so. I have often 

 seen them bite at each other quite spitefully, but their bite seemed to be 

 harmless. But here is surely an instance of decided and continued pugnacity; 

 for to have inflicted the amount of injury that each received must have
