92. BULLETIN 01 THE BROOKLYN ENT. 80C. 



Mentum transversely oval without tooth; supporting the pyriform li- 

 gula, narrowest at base, broadest at middle: palpi two-jointed, the basal 

 very long and thick, the terminal much more slender and shorter; be- 

 tween the two palpi is a triangular prolongation set with three bristles. 



Prothorax glabrous, longer than broad, broader than the head, nar- 

 rower at apex than at base, sides arcuate, front angles obliquely truncate, 

 hind angles slightly distinct. At the sides and the apex there is a small 

 margin, at the base a broad one with longitudinal furrows. 



Mesa- and Metathorax considerably shorter than prothorax, with an- 

 tebasal line; all angles obtuse; glabrous. 



Abdominal segments gradually narrower towards apex, the first the lar- 

 gest, 2d to 7th about equal, 8th much narrower, the 9th the narrowest 

 with a rather stout and short tubular prolongation and the long hairy fork 

 above. The abdominal scutes covering the whole surface are divided by 

 a longitudinal median impressions (as well as the thoracic segments) and 

 are covered with erect hairs. 



The scutes beneath are aranged like in Dicaelus, Spiracles as in 

 Dicaelus. 



At the excursion of the members of the Brooklyn Entomological Soc. 

 May 30th I found at the edge of a brook hidden in the ground among 

 others two small carabideous larvae which appeared when I poured water 

 copiously over the banks. They did not touch meat in confinment, but 

 sucked eagerly scarabaeide larva. June 6th one transformed into a very 

 small pupa. I should have taken the larva for that of Ardistomis viridis, 

 as the species together with Omophron americanum, Nebria pallipes and Plat- 

 ynus extensicottis were found at the same spot. The larva of Omophron is 

 very queer shaped and I thought the larvae and pupae of the other species 

 must be much larger, but June nth the imago developed and proved to 

 be Platynus extensicollis, head and thorax bright green, body and elvtra 

 very light brown.
