62. Hylastes angustatus (Herbst, Kaf. v. iii. 9, tab. 48, 



f. 9, h. ; Bostriciis angustatus, var. nigra), Ericbsou,

This species is included in Mr. Crotch's Catalogue ; but, 

 as there exists some confusion of nomenclature in the genus, 

 and the common H. paUiatus is omitted in the work in 

 question, I cannot be certain which insect the name is in- 

 tended to represent therein. 



I have taken a specimen of H. angustatus, Er., at Holme 

 Bush, and have no doubt that it is mixed with H, opacusin 

 collections. It differs from that species as follows : it is 

 narrower and more elongate ; the punctuation of the thorax 

 is rather coarser, the small spaces between the punctures 

 being shining instead of dull; the tibiae are a little more 

 dilated, differing also slightly in the spines on their outer 

 edge ; and the rostrum exhibits a delicate but decided longi- 

 tudinal channel, the rostrum in S. opacus being without 

 any groove. 



M. palliatics, which also has the rostrum grooved, is a 

 larger, stouter insect, generally brownish instead of black ; 

 with the elytra more deeply and roughly punctured, and the 

 thorax decidedly constricted in front, and with an elevated 

 middle longitudinal line. It differs, also, from both opacus 

 and angustatus in having the third joint of the tarsi more 

 decidedly bilobed.

 Mr. Crotch remarks that this species is exceedingly close 

 to C. bipunctata, Lin. (quadripunctata ?), but distinguished
