NOTOXIDjE. — NOTOXUS. 7^ 



punctate : labrum blacky, impunctate at the base, ciliated at the apex: palpi 

 black: eyes dusky : thorax narrowed before, testaceous, punctate: elytra 

 lurid-yellow, with four obsoletely elevated longitudinal lines not reaching to 

 the apex : breast fuscous ; abdomen dull testaceous, with a black spot at 

 the base: legs pale yellow, with the coxae and knees black; tarsi also 

 black. 



The only known specimen of this curious insect that I have seen 

 is stated to have been taken near Rochford, in Essex. 



Family LXIV.— NOTOXIDtE mihi. 



Mandibles small, stout, the apex slightly bifid, and often diaphanous : maxilltE 

 with two membranaceous lacinise : labium membranaceous : palpi unequal, 

 the terminal joint mostly thickened. Antennas more or less elongate, sub- 

 filiform, rarely serrated within : head nutant, broader than the thorax, to 

 which it is frequently united by a slender neck, or is sessUe thereon : ei/es 

 large, entire : thorax subovate, convex, sometimes produced anteriorly into 

 a hornlike process : eli/tra rigid, rather convex, as long as the abdomen : 

 legs simple; iarsi heteromerous, the penultimate joint generally bilobed; 

 claws simple. 



From the preceding family of insects those of the present family, 

 as separated by me in my Catalogue, differ not only by their compa- 

 ratively minute bulk, but by having the claws simple, the mandibles 

 small, with the apex slightly cleft and somewhat diaphanous, &c. 

 The species are chiefly found on flowers, and are extremely active, 

 running with great facility. Those which have hitherto been detected 

 in Britain may be thus divided into genera : — 



Caput subcordatum ; collum distinctuin. 



y/torax antice in cornu porrectus : . . . 472. Notoxus. 



muticus : 473. Anthicus. 



Caput sessile, collo nullo. 



Femora omnia simplicia.

Genus CCCCLXXII.— Notoxus, Illiger. 



Antenna: rather longer than the thorax, curved, 11-jointed, filiform, the second 

 joint shorter than the third, which is obconic, and the remainder are the 

 same, and of equal length, the terminal joint being oblong and acuminated. 

 Palpi maxillary elongate, the terminal joint large, securiform ; labial with
