new Species of Histeritke. 143 



eye and distant from the margin by one-third of the thoracic 

 length ; the elytra, stria?, inner humeral apical, dimidiate, and 

 curved, dorsal very tine, 1 apparently shortened at the base, 

 2 not traceable at the base or apex, 3 dimidiate and basal ; 

 the propygidium is coarsely punctate, closely so at the sides, 

 more sparingly in the middle; the pygidium is evenly punc- 

 tate ; the prosternum is without stria? ; the mesosternum, 

 marginal stria is widely interrupted; the anterior tibiae 

 4-dentate. 



The frontal striae are a marked character in this species ; 

 the thoracic punctures resemble those usually seen in 0. lace- 

 7-atus, Mars., but Marseul did not notice the punctures in his 

 description of his species, and rightly, as the punctures are 

 sometimes wanting.

Ovalis, convexiusculus, niger, nitidus ; fronte puncticulafca, stria 

 circulari antice vage iuterrupta ; elytris striis 1-2 integris, 3 

 dimidiata punctis continuata; propygidio pygidioque fortiter

L. 6 mill. 



Oval, rather convex, black and shining; the head very 

 feebly impressed longitudinally, stria semcircular, vaguely 

 interrupted anteriorly, surface irregularly punctulate ; the 

 thorax, stria complete, with, a few small punctures behind the 

 anterior angle, behind the eyes away from the margin is 

 faintly seen a somewhat elongate impression (corresponding 

 to the punctures in 0. obliquistrius), scutellar fovea well 

 marked ; the elytra, striae, outer humeral fine and clear from 

 before the middle to the apex, dorsal 1-2 complete, but com- 

 posed of points towards the apex, 3 basal and dimidiate but 

 traceable as fine points to the apex, 4-5 indicated by apical 

 points only, sutural consists of points which disappear beyond 

 the disk ; the propygidium is coarsely and not closely punc- 

 tate, points fewest on the disk, and without foveee; the 

 pygidium is more evenly punctate ; the mesosternum, 

 marginal stria wi lely interrupted, suture well marked by a 

 straight stria.
