CUCUJlDiE. — TROGOSITA. 221 



subdivision, may be very readily known by their very depressed, 

 elongate body, large porrect head, subfiliform or abbreviated com- 

 pressed antenna, and by the integrity of the tarsi. They reside 

 beneath the bark of trees ; and the indigenous species may be thus 

 divided into genera. 



Antenna: extror^um crassiores, compressas : • • 361. Trogosita. 



subfilitbrmes, corpore breviores; laUum plerumque 



bifidum: . 302. Cucujus. 



longiores; /a&mm emarginatum : 363. Uleiota. 



Genus CCCLXI. — Trogosita, Fabricius. 



Antennae short, monilifornij thickened towards the apex ; the four terminal joints 

 largest, compressed, obtusely produced within, and the apical one obtuse. 

 Palpi subequal and filiform, with the terminal joint subovate, truncate : lahrum 

 coriaceous, small, transverse-quadrate: maxillce yiith a single basal process: 

 labium subquadrate, entire : bodi/ elongate, greatly depressed : head large, an- 

 teriorly dentate : thorax subcordate, remote from the abdomen: tarsi obscurely 

 pentamerous, the basal joint small. 



Trogosita is distinguished from the true typical Cucujidse by the 

 brevity of the antennae, which gradually increase in size to the tips ; 

 the integrity of the labium, which is nearly quadrate, and by the 

 remoteness of the thorax from the abdomen ; those parts being se- 

 parated by a space as in the Scaritidse. 



Sp. 1. mauritanica. Nigra, nitida, suhtus rufo-picea, elytris striatis. (Long. 



corp. 3^5 lin.) 

 Te. mauritanicus. imrae.—Tr. mauritanica. Steph. Catal. 195. iVo. 2010. 



Depressed, black, shining : head punctate : thorax thickly punctured : broader 

 anteriorly than the head, with the angles acute : elytra faintly punctate-striate^ 

 the interstices with a double series of impressions : body beneath glossy rufo- 

 piceous, punctured : legs rufo-piceous : antennae the same. 

 I have twice captured this insect beneath the bark of pines at 

 Coombe-wood, and it has been elsewhere taken in similar situa- 

 tions ; but as it has been more frequently observed in this country 

 in flour, dry bread, or rice, its native origin has been recently 

 questioned, although Tenebrio molitor, which is exclusively found 

 in similar substances, is admitted into our Fauna without question ; 

 and the present insect occurs, according to Latreille, " dans toute la 

 France ;"— and also in Germany, Sweden, Portugal, &c. " In the 

 rotten floor of a malt-house at Cambridge."— C C. BaUngton,Esq.
