 LIXUS ANGUSTATUS. 



Order Coleoptera. Fam. Curculionidae. — Yiv'irhimdes, Schon. 



Type of the Genus, Curculio angustatus Fab. 

 Lixus Fab., Schon., Curt. — Phoxus Billb. — Curculio Linn., Marsh. 

 AntenncB rather short, inserted on the side of the rostrum, con- 

 siderably beyond the middle, geniculated, clavate, 12-jointed, 

 basal joint very long and clavate, 2nd and 3rd somevi^hat obovate- 

 elongate, 4 following cup-shaped, the remainder forming a pu- 

 bescent fusiform club of 5 joints (6). 



Labrum ? oblong, membranous, somewhat quadridentate at the 

 apex, which is pubescent and ciliated (1). 

 Mandibles subtrigonate or quadrate, with 2 obtuse teeth on the 

 inside (2). 



Maxilla formed of a large rounded corneous lobe, with a few 

 blunt tubercles on the margin. Palpi very short and stout, tri- 

 articulate, basal joint very broad and short, 2nd somewhat cup- 

 shaped, 3rd subovate with a gland at the apex (3). 

 Mentum oblong, a little dilated at the base and apex, the latter 

 bilobed. Labium corneous, subquadrate, rounded at the base. 

 Palpi short stout and triarticulate, basal joint the largest, pro- 

 ducing 3 strong bristles outside, 3rd joint minute subovate (4). 

 Rostrum nearly as long as the thorax, stout, subcylindric, a little curved, 

 smooth, thickened at the apex, with an oblique groove on each side to 

 receive the antenna. Head small and sho7-t, but not immersed to 

 the eyes which are small, lateral and ovate, but not jirominent (7). 

 Thorax cylindric-conic, truncated before, bisinuated at the base : 

 scutellum very minute. Elytra cylindric-linear, 3 or 4 times as long 

 as the thorax and but little broader, sometimes attenuated and acu- 

 minated at the apex. Wings ample. Legs, anterior approximating 

 at the base: thighs rather long and capitate, anterior sometimes with 

 a tooth beneath : tibise very short and stout, with a curved claw in- 

 side at the apex, strongest in the anterior pair : tarsi as long as the 

 tibia, spongy beneath, 4-jointed, basal joint attenuated at the base, 

 longer than the 2nd which is turbinate, 'Srd cordate and bilobed, 4th 

 slender clavate: claws curved, acute (5, afore leg). 

 Obs. The trophi are taken from L. Bambalio ? Germar, and I ought 

 to observe that I obtained a very imperfect view I fear of the 

 labial palpi.
