•without forming posterior angles, there are no lateral margins, but the 

 pale upper surface is marked off at the sides by the dark-fuscous lower 

 portion. Scutellum obsolete or entirely absent. Elytra shaped like the 

 thorax, but little larger, the straight well-developed basal margin is con- 

 tinued along the rounded shoulders and sides, apices subtruncate ; they 

 ■are seriate-punctate, with slight sutural striae. 



Antennae inserted in sulciform cavities, which are prolonged downwards, 

 immediately in front of the eyes ; they are as long as the head and thorax, 

 the basal 2 joints are subpyriform, joints 3-7 are about equally elongate 

 and a little incrassate at the extremity, 8th subtriangular. rather shorter 

 than 7th ; club laxly articulated, minutely pubescent, and bearing also 

 some setae like those on the preceding joints, the terminal conical. 



Eyes entire, their greatest bulk from above downwards. Tarsi moderate, 

 their .3rd joint with narrow lobes. 



Underside dark fuscous, except along the middle of the abdomen, which 

 is testaceous. Sternum more coarsely punctured than the ventral seg- 

 ments ; the spaces between the punctures are minutely sculptured ; the 

 pubescence is indistinct. 



In size and coloration this somewhat resembles Dysnocryptus testaceus, 

 2217, but the thoracic carina and other structural details are materially 

 different. It is, I have no doubt, the exponent of a new genus. 



Length (rostrum exclusive), 2 mm, ; breadth, l^ mm.

Two individuals onlv were found in Mr. Hall's collection.

Elongate, slightly convex ; the sides of thorax and of the elytra from 

 the base to beyond the middle thighs, and also an irregular fascia behind 

 the posterior femora which is more or less interruptedly prolonged along 

 the suture to the apical scutiform mark, fusco-piceous ; antennae, femora, 

 and middle of elytra rufo-castaneous : tarsi and most part of tibiae testa- 

 ceous ; pubesence flavescent, unevenly distributed, almost entirely absent 

 from the dark areas, the erect setae slender, principally yellowish. 



Head distinctly sulcate along the middle. Thorax widest near the 

 front, narrowed backwards so as to be of the same width as the elytra at 

 the base, it is slightly transverse, coarsely and moderately closely punctured. 

 Scutellum triangular, usually concealed by the pubescence. Elytra oviform, 

 very elongate, nearly thrice the length of the thorax, disc subdepressed, 

 very distantly and irregularly punctate. 



Antennae with fine yellowish-grey pubescence and numerous longer 

 hairs, they do not reach the extremity of the body, 3rd joint about twice 

 the length of 4th. 



The entire absence of crests at once removes it from S. antarctica and 

 its immediate allies. It may be readily separated from 2582 by the' 

 elongated and somewhat flattened elytra, and by the transverse fascia being 

 situated behind instead of being in line with the posterior fermora, &c.
