length of one of the eyes over the head), posteriorly the pro- 

 notal process is acute, extending backward nearly to or a 

 little beyond the knee of hind femora, humeral angles obtuse, 

 between the shoulders rather narrow, transversely between the 

 carinas concave. Median carina of pronotum distinctly cris- 

 tate, longitudinally arcuate, more rarely with a number of 

 translucent punctulations visible when held against the light 

 (not so numerous or apparent as in cojjipresstis)\ lateral and 

 antero-lateral carina; moderately developed ; lateral lobes of 

 pronotum posteriorly bisinuate, the superior sinus shallow for 

 the reception of the elytra; the inferior quite deep, forming 

 nearly a right angle; the little lobule between the two feebly 

 developed, being subconvexed; posterior angle of lateral lobe 

 obtuse angulate. Elytra small, elongate, subacuminate; wings 

 rudimentary, not extended backward so far as the apex of 

 pronotal process. Anterior and middle femora entire, the mid- 

 dle femora more compressed, posterior femora stout; tibia; not 

 at all ampliate at the extremity, multispinose; first, second, 

 and third pulvilli of posterior tarsi successively increasing 

 in length, flattened below, the first and second acute. 



Morse gives the following measurements: 



Total length, ,J, 7.7-9 mm.; pronot., 7.1-8.5 mm.; pro- 

 notum passing hindfem., 1-1.5 mm.; wings passing pronotum, 

 .5-1.3 mm.; length $, 8.6-10.2 mm.; pronot., 8-9.5 tnm.; 

 pronotum passing hind fem., .5-1 mm.; wings passing pro- 

 notum, .7-2 mm. 



In Massachusetts it is reported by Professor Morse to be 

 common locally. He has taken it in every month of the year 

 excepting November. Young specimens were taken in 

 October, commonly of small or medium size, and in June about 

 half-grown; in middle of July very small, and one in the last 

 stage was taken in northern Vermont. It would appear from 

 these observations that the breeding period in New England 

 is later than it is in allied species farther south and west, 

 ovipositing probably being in the latter part of June or early 

 July.
