CRYPTOPHAGID^. 



punctured, 'thorax almost square, colour 

 wholly or in part dark 

 b. Elytra and thorax not so punctured, 

 thorax transverse, colour ferruginous. 

 a*. The thickened part of the anterior 

 angles of the thorax occupying a 

 sixth of the sides, and prolonged 

 behind into a sharp tooth ; thorax 

 nearly one and a half times as broad 

 as long, 

 af. Elytra with the punctures at base 

 about three times as far apart from 

 one another as are those on the 

 thorax, pubescence longer and more 

 abundant ..... 

 bf. Elytra with the punctures at base 

 hardly less coarse than those of 

 thorax, pubescence less abundant 

 and not so long .... 

 b*. The thickened part of the anterior 

 angles of the thorax occupying a 

 fourth or fifth of the sides, and blunt 

 or feebly toothed behind, outstand- 

 ing hairs in rows, thorax about twice 

 as broad as long .... 

 ii. Anterior angles of thorax not produced 

 into a tooth ; lateral tooth before, or at 

 any rate not behind, middle of thorax 

 (but the character is difficult to appre- 

 ciate) ; sides of thorax strongly margined. 



1. Short and broad, very coarsely punc- 

 tured ....... 



2. Somewhat elongate, much more finely 

 punctured ......

G. lycoim'di, Herbst., may be distinguished from^C. setulosus, 

 Sturm., which it superficially i"esembles, by having joints 9-10 of the 

 antennaj not strongly transverse ; in the latter species they are 

 strongly transverse. C. 2nlosns, Gyll., may be known from both by its 

 finer punctuation and the less coarse pubescence of the elytra. I have 

 recorded it (Brit. Col. iii. 316) as one of the commonest species of 

 the genus, but have since then modified my opinion, and believe that I 

 must have confused it Avith 0. badius, Sturm., which I have spoken of 

 (I.e. p. 320) as one of the less common species, whereas it is apparently 

 much commoner than C. pilosics. Mr. Newbery has sent me the 

 following additional characters for distinguishing these last two 

 species :
