gitudiiial iiiii>ressions deej), slightly ohliquc and extending oiie-tliiid the length 

 of tlie thorax. Elytra not wider at hase than the thorax, humeri ohli((uely 

 rounded, umboue moderate and smooth, dise convex, with niue strife of moder- 

 ately coarse punctures, rather closely placed near the base, more distant and finer 

 at apex, the ninth distant from the margin, a scutellar stria extending one-third 

 from base, intervals flat, very minutely, sparsely punctulate. Prosternum 

 coarsely and closely punctate, the pleurfe smooth. Abdomen rather closely punc- 

 tate, scabrous, first segment smoother. Length .12 inch. ; 3 mm. 



In this species the metasternum is prolonged in front in an acutely 

 oval i^rocess, almost meeting the ])rosternLnn, and the mesosternum 

 is consequently practically invisible. In all the species of Crej)ido- 

 dera (sensu Chapuis) the metasternum varies in form in such a man- 

 ner as to render it impracticable to use it for the separation of genera. 

 By the Chapuis table robusta would, in all probability, be supposed 

 to be a Mniophilite, but these have the anterior coxal cavities open 

 and the thorax without transverse impression. 



With the general form oi Modeerl the present species has the thorax 

 more convex than usual, so that the head is scarcely visible from 

 above. The ninth discal stria is rather distant from the marginal, 

 a cliaracter unknown in our other species. It is probable that ro- 

 hiistd. should be separated generically, and with other species having 

 similar characters such a course would be advisable. 



By a clerical error Di-. LeConte describes the thorax as twice as 

 hmg as wide. 



This species is rare at present ; the only two known to me, except 

 the type, are in the collections of Mr. Blanchard and Mr. Ulke, who 

 have kindly given me the use of all their material.

V. ]?Iodeeri Linn.— Oval, narrowed in front, moderately robust, piceous, 

 with slight aeneous lustre, apical third of elytra indeterminately testaceous. 

 Antennse half as long as the body, yradiuilly broader externally, brownish or 

 piceous, the four basal joints pale. Head alutaceous, sparsely punctate, frontal 

 carina distinct, but obtuse, the tubercles not well defined. Thorax one-half 

 wider than long, sides nearly parallel behind, arcuately narrowed in front, disc 

 convex, a moderate ante-basal transverse imi)re,ssion, limited at each end by a 

 deep longitudinal impression which extends slightly in front of the transver.se 

 one, disc convex, surface alutaceoiis, the punctures coarse, moderately close, but 

 not deep, behind the impression smoother. Elytra distinctly wider at base than 

 the thorax, humeri obtusely rounded, umboue moderate, slightly impressed 

 witiiin, disc moderately convex, scutellar stria long, disc with nine strise of 

 coarse punctures, moderately closely placed near the base, becoming finer and 

 more distant near the apex, the ninth stria not distant from the margin. Pros- 

 ternum coarsely and closely punctured, the i)leune smooth. Abdomen finely, 

 indistinctly ])unctate, with fine pubescence- Legs brown, the anterior and mid- 

 dle pair usually paler, Length .08 — .10 inch. ; 2—2.5 mm.
