ENGIDiE. CRYPTOPHAGUS. 77 



an obsolete denticulation towards the middle ; the space from thence to the 

 base finely crenulated: legs and antennae pale rufo-ierruginous. 

 Smaller than either of the foregoing ; less distinctly punctate ; the sides of the 

 thorax less denticulated and somewhat crenulated. 



Frequently taken in the metropolitan district ; also in Suffolk. 



Sp. 9. Abietis. Oblongior, ferrugineus pubescens, thorace postics angustiori 



margine serrato antice unidentato. Long. corp. 1 — 1 1 lin,) 

 Cr. Abietis. Paykul.—Steph. Catal. 86. No. 930. 



Rather oblong, of a deep rufo-ierruginous, thickly punctate, pubescent: antennae 

 ferruginous, rather slender, with the tip paler : thorax subquadrate, rather 

 broader anteriorly than its length, and narrower posteriorly, the disc rather 

 convex, finely punctulate and slightly pubescent; the lateral margin with the 

 anterior angle somewhat reflexed and produced into an obtuse tooth, from 

 thence to the hinder angle finely serrated ; elytra elongate : body rufo-tes- 

 taceous : legs paler. 



The crenulated bidentate margin to the thorax, as well as the greater length 

 and convexity of the insect, although of smaller size, distinguish this species 

 from the preceding. 



Not very abundant ; found chiefly on the spruce fir, and also in 

 houses, &c, near London, at Bristol, &c. " Near Swansea." — L.

Sp. 10. cellaris. Oblongo-ovatus, Jusco-ferrugineus, pubescens, etytris nigro- 

 fuscis, thorace brevi lateribus bidentatis, post ice crenatis. (Long. corp. 1— 1 1 

 lin.) 



Cr. cellaris. PaykuL—Steph. Catal. 86. No. 931. 



Oblong-ovate, fusco-ferruginous, slightly punctate and pubescent ; thorax short, 

 the disc slightly convex, thickly and somewhat faintly punctured, the margin, 

 especially the posterior, dusky, the lateral ones produced at the anterior angle 

 into an oblique acuminated tooth, and in the middle into an acute promi- 

 nent one; from thence to the posterior angle very finely crenulated; scu- 

 tellum black; elytra acute, clothed with a pale pubescence, sometimes 

 entirely black, at others with the base dull ferruginous, or entirely pale 

 testaceous; body beneath pitchy-ferruginous; the apex paler; legs pale 

 testaceous. 



Very variable ; in some instances the entire surface is rufo-testaceous. 



The posteriorly crenulated and bidentate lateral margins of the thorax, and 

 usually deep fuscous or black elytra, with the base more or less ferruginous, 

 are the most evident characters. 

 In certain years this insect is far from uncommon in particular 



situations: in the autumn of 1815 I found a considerable quantity 



of specimens in an old house that was undergoing- repair, at Hert-
