Tliis sj)ecies has tlie femur siniiliirly dilated, hut a little more an- 

 gulate heneath. The trochanter is scarcely half the length of the 

 femur. In the majority of specimens there is no scutellar stria, and 

 in a few a mere trace of it.

In this the posterior femur scarcely differs from the normal form. 

 The trochanter is not half the length of the femur. The scutellar 

 stria is moderately long. 



In a letter to me written after the puhlication of LeConte's review 

 of Pterostichus, Baron Chaudoir insists that hrunneus is not a synonym 

 of eastane us, but has a subelongate scutellar sti'ia, and is consequently 

 the same as scutellaris Lee. 



In the same letter Chaudoir asserts that his F. dilif/endus is exactly 



P. mancus Lee. The following synonymy must he adopted : 



P. inaiiciis Lee, diligendus Chd. 



I*. apalii('liiu»i Lee. mss., diligendus J Lee. 



The name suggested is that at first given by Dr. LeConte in his 

 cabinet. 



P. iniitiis Say. 



Recently Mr. J. F. Hansen, of Montreal, has described two .spe- 

 cies at the e.xpense of viidus, which he has called pidvimdus (Natu- 

 raliste Canad. v, p. 20, 1891) and Me}i(i})s (Canad. Record of Science 

 iv, p. 25'2). These are simply individual variations. 



TREC'HUS t'lairv. 

 T. barbarse n sp. — Rufo-testaceoiis, elytra piceo-testaceous, moderately 

 shining. Anteunje ferruginous, paler at base. Head finely alutaceous, inipuuc- 

 tate, frontal depressions broad, but very vague. Thorax a little wider than long, 

 base shorter than the length, sides arcuate in front, sinuate posteriorly, liiud 

 angles not prominent, base slightly oblique each side, lateral margin very narrow 

 and not wider at base, disc feebly convex, smooth, a fine median line. Elytra 

 regularly oblong oval, humeri obtusely rounded, disc smooth, with the usual 

 dorsal punctures, but without traces of striie. Hody beneath smooth and shining. 

 Length .18—20 inch.: A.^—^ mm. 



This species has well developed eyes, and differs from all our spe- 

 cies in the form of the thorax and its very nari'ow margin, the verv 

 sliailow frontal grooves, and the entire absence of traces of stria' on 

 the elytra. 



I have seen three specimens of this species obtained b}' Mr. Chas. 

 Fuchs from Santa Barbara, Cal., which agree, except as to size; two 

 were males, one female.
