NEW BRITISH SPECIES, ETC., IN 1865. 85 



The family of the Thorictidce, placed between the Myce- 

 tophagidce and DermestidcE, appears to contain two genera ; 

 one, ThoTictiis, Germ. { Splicer ophorus, Waltl.), of 13 species, 

 occm'ring in Syria, Egypt, Oran, Caucasus, Algiers, &c. ; 

 and the other, 3Iyrmecohius, Luc, of one species, agilis, 

 Luc, found at Bone. 



35. Cryptophagus serratus, Gyll. Ins. Suec i. 171, 7; 



Erichs. Ins. Beutschl. iii. 374, 5 (Paramecosoma) ; 

 De Marseul, Cat. Col. d'Eur. &c ; G. R. Crotch, 

 " The Entomologist," vol. i. p. 210, 147. 

 Mr. Crotch remarks that this fine species, referred by 

 Erichson to Pai'aniecosoma, is rightly placed in Cryptopha- 

 gus by Thomson (Skand. Col. v. 250, 1). The only speci- 

 men he has seen was brought from Scotland by Mr. Charles 

 Turner, from whom it passed into the hands of Mr. E. W, 

 Janson. 



It appears to be distinguishable from any other of the 

 Cryptophagi by its uniform dark-pitchy colour ; the equally 

 and plainly serrated edges of its thorax, of which the an- 

 terior angles are not elevated j its strong punctuation — the 

 sutural stria of its elytra being sub-conspiciious in front — and 

 by the penultimate joint of its tarsi being less than the pre- 

 ceding. 



It is about the size of C. scanicus ; and should be found 

 on female blossoms of the sallow. 



36. Atomaria diluta, Erichson, Ins. Deutschl. iii. 380, 6 ; 



R. Hislop, Ent. Monthly Mag. vol. ii. p. 139. 



Taken by Mr. Hislop and Mr. Sharp in Scotland (by the 

 latter gentleman near Edinburgh). 



It belongs to the section in which the antennae are closely 

 approximated at the base ; and is large, testaceous, shining,
