THE CANADIAN ENTOMOLOGIST. 93 



This species, the female of which is at once conspicuous by reason of 

 the shape and size of its ovipositor, has been taken in small numbers only 

 in Vigo Co., where it is found during August and September on the leaves 

 and stems of a tall, broad-leaved knot-weed, Polygonum amphibium, L., 

 which grows luxuriantly in the shallow waters about the margins of two 

 or three large ponds in the Wabash River bottoms. Several other " green 

 grasshoppers," notably among which are Xiphidium attemiatuin, Scudder, 

 and Orchelimum nigripes, Scudder, frequent this plant in immense num- 

 bers. Keeping company with them an occasional specimen of 0. Bruneri 

 is seen, but, being an active leaper, it often escapes amidst the dense 

 foliage of the knot-weed before its capture can be effected. Its less 

 robust body and longer armed posterior femora will readily distinguish 

 this species from O. gladiator, the only other one which, to my know- 

 ledge, has an ovipositor shaped like that of Bruneri. The latter is 

 named in honor of Prof. Lawrence Bruner. of Lincoln, Nebraska, one of 

 the leading authorities on N. A. Orthoptera.

BY HARRISON G. DYAR, BOSTON, MASS. 



Phyciodes carlota, Reak. 



Larva. — Head subcordate, apices slightly produced, mouth parts 

 small ; rough, tuberculate, hairy ; colour black, a narrow white line above 

 the mouth. Body robust, with short and thick conical, densely-bristly 

 spines, arranged thus : on joint 2 one short stigmatal and one substigmatal, 

 besides tubercles on the cervical shield ; on joints 3-4, subdorsal, 

 lateral and subventral ; on 5-1 r, dorsal (single), suprastigmatal, substig- 

 matal, 2 subventral ; on 12, two dorsal (in line), subdorsal, superstigmatal, 

 substigmatal and subventral (small); on joint 13, two subdorsal (in line). 

 Cervical shield, anal plate, feet outwardly and spiracles black ; body 

 brownish red, with a dorsal and subdorsal black shaded line, most distinct 

 in the segmental incisures. 



Pupa. — Straight on ventral side; thorax with no prominence; abdomen
