24 HIANDIBULATA. COLEOTTERA. 



rather broader than loni^-, slightly convex, with the sides founded, distinctly 

 punctured, with an obsolete dorsal line : cJt/tra thickly rugose- jmnctute, with 

 the apex obtuse, or hut slightly produced : legs rather short, stout : antcnnic 

 also short, with all the joints from the third abbreviated, and somewhat 

 moniliform. Male smaller, rather narrower, with a tuft of hair beneath at 

 the base of the abdomen, the elytra more produced, and the logs rather 

 longer. 



Not common near London, but not unfrcquent in houses and 

 stables at Hertford in June. " Weston."" — Rev. A. H. Matthews.

Family LVIII.— HELOPIDiE mihi. 



Mandibles bifid at the apex, or entire : maxilla; with two lacinise, not unguicii- 

 lated : mentum generally small : labium elongate, membranaceous, deeply 

 emarginated : palpi with the terminal joint elongate, and somewhat trigonal. 

 Antennae 11-jointed, filiform, with the articulations subcylindric, and some- 

 times produced on the inner margin : head small, ovoid, deeply inserted into 

 the thorax, without any posterior contraction : bod/i/ elongate : elytra ample, 

 free : wings generally ample : legs long, rather slender, simple : tarsi with 

 entire joints, anterior sometimes dilated in the males ; heteromerous. 



The insects of this family are of rather more lively hues than those 

 of the foregoing ; their elytra are free, and the species are generally 

 provided with ample wings, excepting in the first genus, which has 

 them abbreviated : in their larvae state they are found in wood, or 

 under the bark of trees, but many of them frequent umbelliferous 

 flowers in their final state. The indigenous genera may be thus 

 distinguished by the following simple characters : 



Mandilulce apice bifidce, aut fissce.
