COLEOPTERA CUCUJIDES. 149 



has been placed by Gyllenhal and Stephens in this subfamily, which 

 has been removed to a wide distance from its legitimate affinities. The 

 body is oblong and depressed {fg. 12. il. C. picciis) ; the head large 

 and porrected, with a rounded labrum (^fig- 12. 12.), powerful exserted 

 jaws {jig. 12. 13.) ; the outer lobe of the maxillae is broad, and the 

 inner lobe small, and often reduced to a mere hook (^fig. 12. 14.) ; the 

 palpi are short, filiform, or but very slightly thickened at the tips; the 

 labrum produced, and often bilobed (^^r. 12. 15.); the antennae are 

 generally longer than the head and thorax, and of equal thickness 

 throughout, or moniliform ; in some species, however, they are cla- 

 vate ; the thorax is generally subquadrate ; the joints of the tarsi are 

 simple, entire, and generally five in number, the basal joint being often 

 very minute, and occasionally obsolete in the posterior legs, so as to 

 cause the insect to appear heteromerous (^fig. 12. 17. posterior tarsi 

 of the male, and 12. 18. ditto of the female C. Freyersii Van H.). 

 These insects are of small size, and are chiefly found beneath the 

 bark of trees or in decaying wood. One species, C. Spartii, occurs 

 at Coombe Wood, under the bark of old stumps of white broom ; and 

 C. C. Babington, Esq., F.L.S., informs me that he meets with another 

 species (C. testaceus Steph.) in plenty in a granary at Cambridge. I 

 also discovered many specimens of the same species creeping up the 

 walls of a granary at Hamburgh.* 



I have discovered the larva of Cucujus Spartii in the same situa- 

 tions as the perfect insect. It is long, narrow, and subdepressed 

 (^Jig. 12. 19.), of a fleshy consistence and white colour, except the 

 head and terminal joint of the body, which are of a yellowish-brown ; 

 with short ^-jointed antennae and six short legs ; the thoracic seg-

* Tn this respect, as well as in the similarity of the structure of the larva', tliore 

 is the strongest resemblance between Trogoslta and Cucujus.
