and leas approximate than tliose on the head and prothorax. Head broad, the 

 eyes large and convex; antennae rather short, sleuder, joint 3 about as long 

 as 2, 4-11 moderately elongate. Prothorax hollowed in front opposite the 

 eyes, the anterior angles prominent, obtuse. Scutellum large, somewhat 

 convex. Elytra broad, rounded, sinuate at the sides when viewed in profile, 

 the margins explanate and sharply carinate, slightly sinuate near the sutural 

 angle, the intni-humeral callosities smooth, prominent, the disc regularly 

 convex. Ventral segment o with a large, deep, smooth fovea in the middle. 

 Posterior coxal plates transversely subquadrate. Posterior legs not very elon- 

 gate, stout, the femora extremely broad, the tibiae widened, feebly curved 

 and sharply carinate, the upper spur nearly as long as the first tarsal joint.

TROGOPHLOEUS IMPRESSUS Lac. : AN ADDITION TO THE LIST OF 



BRITISH COLEOPTERA. 



BY E. A. JfEWBEEY. 



This little Trogopliloeus is very nearly allied to both T. elongatulus 

 and corticinus. Granglbauer (Die Kafer Mitteleui'op. ii, 653) compares 

 hnpressus with the latter, but it appears to me, by reason of its dull 

 head and thorax, to more nearh'^ resemble the former. 



Rey, in his table (Oxyteliens, pp. 294, 295), separates it from both the 

 above species b}^ its evidently more slender antennae ; a slight modifica- 

 tion of this table will easily separate the three species : 



I. The 4th and 6th aiitennal joints not or scarcely transverse. 



T. impressiis Lac. {inquilinus Er., ohsoletus Mills. & Rey). 

 II. The 4th and 6th antennal joints distinctly or strongly transverse. 



A. Head and thorax visibly punctured, shining T. corticinus Grav. 



B. Head and thorax shagreened, dull T. elongatulus Er. 



The thorax of impressus is much less shining than that of corti- 

 cinus, but a little more so than that of elongatulus, being more evidently 

 punctured ; its slender antennae is a marked character. 



I have but a single specimen of impressus, taken in July 1887, by 

 sweeping the sides of the ditch parallel to the Thames east of Hammer- 

 smith Bridge, a jDrolific locality at that date. The insect could not be 

 named at the time, and it was placed in my collection as " unknown
