Head (including the prominent eyes) as wide as front of 

 thorax ; Lateral grooves dee)), each separated from the eye by 

 a distinct carina, frontal impressions elongate and rather 

 shallow, feebly sculptured ; there is a slight constriction and 

 a series of small punctures behind the eyes. Thorax almost 

 as long as broad, widest near the front, lateral margins fine 

 but distinct, its sides a very little rounded till near the minute 

 sinuosity or oblique contraction at the obsolete posterior 

 angles ; disk smooth, its longitudinal groove abbreviated, 

 basal fossse rather elongate and situated close to the angles, 

 between these there are a few minute punctures. Elytra 

 elongate, very little curvate at the sides, shoulders quite 

 obtuse and a good deal narrowed ; their striae rather shallow 

 and finely punctured. 



Antennce reaching backwards to middle of thorax, basal 

 three joints and part of fourth glabrous, remaining joints with 

 conspicuous yellow pubescence. 



Legs moderately stout, tibiae not prolonged or incrassate at 

 the extremity, the anterior with six coarse spiniform seta3 on 

 the outer face near the apex. 



Male. — Anterior tarsi with fine set» at the sides, basal four 

 joints somewhat expanded ; tlie basal two largest, second 

 quite transverse but not exactly cordate, these two articula- 

 tions broadly dilated inwardly and furnished underneath at 

 the inner side with patches of grey sponge-like vestiture.

Preservation Inlet {Mr. Hansen). One individual. 



Obs. — The structure of the male anterior tarsi in this and 

 my D. ininctipenne (no. 1768) proves that Dr. Sharp^s genus 

 is not only perfectly distinct, but that it is differentiated 

 by structural characters that cannot well be mistaken. He, 

 no doubt, had seen female specimens only when instituting 

 Diglymma. 



Snofru, gen. uov. 



Body cylindric. Allied to Diglymma. 



Mentum tooth large, grooved, but not distinctly du])licate, 

 strongly bisetose at base. Maxillary palpi v>'ith. subcylindric 

 terminal joints, truncate at apex. Labial of about similar 

 length, penultimate joint strongly bisetose, the terminal about 

 as long as that of the maxillary, moderately slender at its 

 base, considerably dilated beyond, narrowed but not acumi- 

 nate at the extremity ; if the apical portion were removed 

 the joint would be securiforui. Scrobe of mandibles seti- 

 gerous. There is but one ocular seta; each side of the thorax
