TENEBRIONIDAE. 397 



but not deeply bisinuate, with slightly projecting rectangular angles, apex 

 subtruncate in the middle but with its angles extending to the transverse 

 eyes ; its sides broadly jflattened, widest at or before the middle, each with 

 about 6 moderate indentations ; disc transversely convex, but somewhat 

 impressed or flattened along the middle, its sculpture irregular, nowhere 

 very close, consisting apparently of minute asperities. Elytra oblong, 

 considerably narrowed and subvertical behind, more than double the length 

 of thorax, a little broader than it is at the base, and slightly incurved there, 

 with obtuse shoulders ; they are without definite striae or punctures, but 

 have irregular series of minute, somewhat unequal asperities or granides ; 

 there is a slight lateral plica at each shoulder, and near each side, behind 

 the middle, there are 2 or 3 slight, suboblong elevations, these are 

 sometimes confluent, and unite with the horizontal nodosity at the top of 

 the posterior declivity, just inside and below this nodosity there is a dark 

 angular depression. 



Underside infuscate, its granular sculpture becoming finer from front 

 to rear. Prosternum broadly grooved between the coxae. The suture 

 between the intermediate coxae is obsolete. Basal ventral segment not 

 twice as long as the next and subtruncate between the coxae, 4th shortest, 

 the broad sides are coarsely subseriate-pmictate or granulate according to 

 the point of view. 



Antennal joints 7-10 transverse, abruptly shorter than preceding ones, 

 the terminal subconical. 



The almost wholly nigrescent surface of the typical species (2376) 

 distinguishes it. 



Length, 6-6J mm. ; breadth, 2f mm. 



Gordon's Knob, Nelson ; 15th November, 1914. Three specimens 

 obtained by Mr. T. Hall. A fourth measures 7| mm. by 3| mm., and is 

 almost entirely fusco-testaceous.

Depressed, elongate, subopaque, variegate ; pubescence slender, elongate, 

 tawny-grey, closer on the elytra than on the thorax, flavescent on the head ; 

 elytra dull fuscous, faintly olivaceous when alive, the suture and lateral 

 margins pale testaceous ; head and thorax a little nitid, fusco-fulvous, the 

 former with a large interocular spot, the latter with a broad vitta along 

 the middle, and its sides, fusco-piceous ; legs, antennae, and palpi fuscous, 

 the knees and tips of the palpi testaceous, femora fulvescent near the base. 



Head of about the same length as thorax, finely punctate. Thorax 

 slightly longer than broad, widest and moderately rounded before the 

 middle, base and apex feebly medially emarginate ; closely and finely 

 punctate, with a central impression at the base. Scutellum subquadrate, 

 testaceous. Elytra nearly double the width of thorax, four times its 

 length, shoulders rounded, apices strongly so and almost entireh' covering 

 the pygidium ; their close and fine punctation continuous, each eh'tron 

 feebly bicostate. 



Underside finely pubescent, the breast and coxae fulvescent ; abdomen 

 fuscous, its 5th segment as long as its predecessor, entire.
