 rax, and region of scutellum bronzed, intermixed with a bright

CYCHRUS 



ViDUUsDej.; unicolorSa.j. Newm. (Irichroa) Ent. 



Palpi 4, claviform at the apex; antenuEe 11-articulate — the 

 basal joint longest : 2d, 3d, and 4th short, black, and polished; 

 5th to the apex brown pubescent; jaws elongate and toothed; 

 head black and incline downwards; thorax margined — with 

 longitudinal groove through the disc, and two depressions 

 behind, reilecting a steel-blue colour, and densely punctured ; 

 elytra polished, with a punctured bluish margin — longitudi- 

 nally punctured in rows, which become more irregular and 

 rugose near the posterior. The elytra are greatly rounded 

 posteriorly, and do not terminate in a direct point; body 

 beneath black. Toronto, 7th April, under leaves ; not com- 

 mon. Length 5 lines. 



HISTER 



BiMACULATUS Lin. ; obliquiis Say; reniformis Jardine's 

 Nat. Lib., vol. vi. pi. 9, fig. 5. 



Antennpe deflexed in the centre — the base forms an angle

One specimen of the above was taken in Toronto in May 

 last, which corresponds with Jardine's figure in the work above 

 cited ; but the length of the specimen from which the icon was 

 taken is omitted. "Reniformis" maybe synonymous with the 

 European " bimaculatus," which also occurs in America.

RURICOLA. — Meh. Cat. Antenna short, and of a rust co- 

 lour ; head and thorax black, the latter globular, and sur- 

 rounded by a yellow margin ; scutellum yellow ; elytra blackish, 

 and from the region of scutellum a short yellow fascia points 

 obliquely towards the lateral margin, and behind the latter 

 fascia there is a zigzag yellow band, having a similarity to the 

 letter W, as in clytus sjieciostis. Posteriorly there is a yellow 

 transverse arch ; tibias and upper section of femoras of a rusty 

 colour — the latter clavate ; posterior legs the longest ; pectus 

 spotted with yellow ; rings, of abdomen yellow. Common

Antennae longer than the body ; head and thorax black, the 

 latter round, and sprinkled with short whitish hairs ; elytra 

 greatly abbreviated, covering but half the body, and spread 

 apart behind ; femoras clavate. 



From the transparency of the elytra, the folded wings can be 

 seen beneath, which may have led Mr. Say to name it " bima- 

 culatus." Toronto, common on Wild Parsnip. Length 2 lines.
