238 On neio Species of IVistevidds. 



punctures are rather large, but behind the median impression 

 tliey are smaller ; the pygidium has a rather large depression 

 on either side of its base, and it is more regularly punctured 

 than the propygidium ; the prosternum and mesosternum are 

 finely punctulate, the transverse stria of the latter is minutely 

 crenulate; the anterior tibite are G-dentate. 



Omalodes sinuaticolUs, Mars., has a similar elytral fovea 

 to this species, and the two species are similar in outline, but 

 the frontal fovea, sculpture of the pygidia, and the transverse 

 stria between the meso- and metasterna are distinctive 

 characters in foveipennis. In several specimens there are 

 thoracic fovete, but they are not constant either in number or 

 position.

The prosternum in this species is bistriate between the 

 coxfe, and the mesosternal marginal stria is complete and 

 punctate. 



Hister viundulus, sp. n. 



Ovatus, convoxns, niger, nitidus ; fronte punctulata, stria Integra ; 

 pronoto stria interna antice late iuterrupta ; elytris striis 1-4 

 integris, 5 ultra medium extensa, suturali ante basin ahbreviata ; 

 propygidio pygidioque punctulatis. 



L. 4^-51 miU. 



Oval, convex, black and shining ; the head finely and some- 

 what densely punctulate, stria complete and semicircular, but 

 feebly irregular in its course; the thorax, marginal stria 

 very fine laterally, but much more distinct behind the head, 

 inner lateral not quite reaching the base, hamate and ceasing 

 behind the anterior angle ; the elytra, strias, outer humeral 

 short and median, inner wanting, dorsal 1-4 complete, 5 

 reaching just beyond the middle, sutural shortened before the 

 base and turning away from the suture apically, all the strife 

 are crenulate ; tiie propygidium and pygidiura are somewhat 

 faintly punctulate, very fine points are set in between the larger 

 ones ; the prosternum, anterior lobe margined wnth two striae 

 laterally, the outer stria the shorter, keel narrow between the 

 coxae ; the mesosternum, marginal stria is complete and fine, 

 also that of the metasternum, the latter continues conspicu- 

 ously in a loop to the elytral margin ; the anterior tibice are 

 bifid, with three simple teeth above them.
