Rostrum slightly dilated at apex, little more than half the length of 

 thorax and about as broad as rhe short head, with a ridge along the middle 

 ending in a broad interocular depression. Thorax a good deal, yet not 

 abruptly, narrowed in front, rather broader than long ; the surface a little 

 uneven, with a broad frontal impression near each side, the median im- 

 pression distinct at the base, less so in front, the punctation entirety hidden. 

 Elytra oblong, narrowed and vertical behind, twice the length of thorax, 

 broader than it is, medially incurved at the base, thus causing a sublunate 

 gap between it and the thorax, the shoulders obtusely prominent ; they 

 seem to be coarsely seriate-punctate ; the 3rd interstices are unevenly 

 but only moderately elevated, somewhat prominent at the base, and termi- 

 nate as nodiform elevations on the summit of the apical declivity ; the 

 5th are less raised, and the posterior nodosity on each is smaller than that 

 on the 3rd, and does not extend quite as far back ; the suture is obtusely 

 elevated behind. 



Legs coarsely setose, tibiae a little flexuous, mucronate, with fine ful- 

 vescent setae near the extremity, the posterior with some denticles along 

 the inner or front face. Tarsi finely setose above, their penultimate joint 

 moderately dilated and bilobed, the terminal nearly as long as the others, 

 taken together. 



Scape inserted near the apex, barely attaining the thorax, very gradu- 

 ally incrassate, dull, bearing pale squamae and outstanding setae. Funi- 

 culus more finely setose, the basal joint longer than the elongate 2nd, 

 3rd of about length and breadth, joints 4—7 moniliform. Club oblong-oval, 

 densely and minutely pubescent, indistinctly triarticulate. 



There are no ocular lobes or scutellum. The eyes are free from the 

 thorax, widely separated above and subacuminate below. Scrobes open 

 above, subapical, extending half-way to the eyes. Posterior corbels with 

 duplicate cilia and distinct but not broad truncations externally. 



The typical species (763) is distinguishable by a glance at the spiniform 

 process near the base, on the inner face, of the hind tibiae ; the other (2099) 

 by the mesial thoracic depression being deeper near the front. 



The sappy, scale-like encrustation is hardly removable with the point 

 of a needle, the actual sculpture, therefore, is invisible. 



Length (rostrum inclusive), 7imm. ; breadth, 31^ mm.

 D.Sc, who found it in the cultivated ground at Lincoln Agricultural 

 College.

 p. 1177. 



Convex, elongate, slightly nitid, nigrescent ; antennae, tarsi, and knees 

 more or less ferruginous, legs rufo-piceous ; sparingly clothed with small 

 nearly white squamae and slender suberect setae. 



Rostrum nearly as long as thorax, slightly arched, not quite as broad 

 as the head, but not at all abruptly narrower, irregularly punctate, and 

 with a fine median carina. Eyes large, transverse, nearly flat, not quite 

 as distant from the thorax as they are from each other. Antennae mode- 

 rately stout and elongate ; scape gradually thickened, and attaining the 

 thoracic margin ; basal joint of funiculus rather longer than 2nd, 3rd 

 and 4th obconical, 5-7 bead-like ; club oblong-oval, triarticulate. Thorax 

 slightly broader than long, moderately rounded laterally, a little narrpwer 

 in front than at the base, not uneven above, Vv'ith a short smooth central
