carinse tliongh mimite are distinct; the disk shows one minute trans- 

 verse incision a little beyond the middle; posterior margin obtusely 

 rounded. 



Elytra extend beyond the abdomen ; lower (costal) border somewhat 

 expanded about the middle, and diaphanous ; wings as long as the ely- 

 tra. Posterior femora extend to the tip of the elytra. Subanal plate 

 subconical. 



(7oZor,(dried). — Face pale, testaceous; mouth-parts whitish. Upper sur- 

 face of the head and pronotum testaceous brown along the central por- 

 tion, with a black stripe each side extending from the vertex to the x:)os- 

 terior extremity of the pronotum, filling the space between the outer 

 median and lateral carinte, though at the curve of the lateral carinje 

 it shows a slight dash exteriorly ; lateral carinae bright yellow ; sides 

 testaceous, darkest along the middle portion, paler below. Elytra testa- 

 ceous-brown, with two or three irregular fuscous and pale spots along 

 the disk. Wings (not opened) fuscous at the apex. Posterior femora 

 dull-yellow; upper carinte slightly touched with fuscous; tibite dull- 

 white (probably bluish when living) ; spines tipped with black. Basal 

 portion of the antennee testaceous ; club fuscous. 



Dimensions. — $ , Length to tip of elytra, 0.64iuch; elytra, 0.48 inch; pos- 

 terior femora, 0.40 inch; posterior tibise, 0.37 inch. 



Gomi^hocerus carpenterli, sp. nov. 



Male. — Anterior tibiae enlarged ; disk of the pronotum gibbous ; very 

 similar to Stenobothrus sihiricus, Fisch. 



Vertex triangular in front, thecariuate margins forming a right angle 

 at the apex, scarcely expanding in front of the eyes, horizontal ; lateral 

 foveolse distinct, linear. Face somewhat oblique ; frontal costa rather 

 broad, fiat, not sulcate, and only very slightly indented at the Ov^ellus, 

 above which it is punctured, and below which it extends but a short dis- 

 tance ; lateral carinse subdistiuct, diverging. Antennae little longer 

 than the head and thorax ; club flat, ovate, commencing about the six- 

 teenth or seventeenth j oint. Pronotum of nearly uniform width through- 

 out ; the sides and disk gibbous, the swell of the sides being chiefly on 

 the anterior portion of the middle lobes, the swell of the disk on the middle 

 lobes, but is distinctly limited by the posterior transverse incision ; the 

 posterior incision cuts all the carinee, but does not notch them; it is 

 situated considerably behind the middle ; the middle transverse incision 

 is somewhat distinct, but on the sides only; two punctures on the disk 

 appear to represent the anterior transverse incision (in my unique 

 specimen) ; the three carina; distinct minute, the lateral strongly curved 

 inward near the middle, posterior extremity obtuse-angled. Elytra a 

 little longer than the abdomen ; narrow at the base and expanding a 

 little more than usual in the middle ; nervules of the costal margin dis- 

 tant, parallel ; nervules of the middle field somewhat distant, mostly 

 transverse and scalariform. Wings about same length as the elytra. 

 Posterior femora a little longer than the abdomen; anterior tibiae con- 

 siderably enlarged; middle tibiae of the usual form. Posterior part of 

 the pronotum minutely tuberculate. 



Color (after immersion in alcohol). — Brown, shaded with black. Face 

 pale cinereous; cheeks mottled with fuscous; toi3 of the head black, 

 with a palish stripe along the middle of the occiput. Middle and ante- 

 rior lobes of the pronotum dark-brown, with some paler markings on the 

 sides; the posterior lobe, with the upper portion of the sides, including 

 the lateral carinse and a middle stripe, dull rufous ; the interspaces of
