(according to my arrangement) but it is hardly likely to differ in 

 these respects from species evidently allied to it and themselves 

 having these parts very uniform. It may be added that Erichson 

 does not indicate the number of joints in the antennae of H. 

 dimidiatus except by implication in calling it a Silopa^ — and he has 

 certainly included some species with 8-jointed antennae under the 

 name, although in the generic diagnosis he calls the antennae 

 9-jointed. 



H. JUBATUS, sp.nov. 



Minus elongatus ; postice vix dilatatus ; minus nitidus ; pilis 

 (antice longis erectis, postice brevioribus adpressis), sat dense 

 vestitus j piceo-niger; palpis, elytris (basi minus late picea excepta), 

 tarsisque, ruf o-f errugineis ; abdomine tibiisque plus minus rufes- 

 centibus ; capite crebre rugulose (clypeo parum subtilius crebrius), 

 prothorace elytrisque crebre subtilius, pygidio leviter obscure,

 multo, brevioribus ; elytris substriatis, interstitiis obsolete con-

Var. A. Pedibus plus minus testaceis, colore obscuro in ely- 

 trorum sutura et marginibus lateralibus plus minus producto. 



Var. B. Elytris antice hand obscurioribus. 



Yar. C. Capite (palpis rufis exceptis) corporeque subtus antice, 

 solis piceis. 



The "trilobed" appearance of the front outline of the head is 

 not well defined from any point of view as it is in itself very 

 feeble, and viewed from the most favourable point is much con- 

 cealed by the long erect hairs of the surface ; its appearance from 

 the most favorable point of view is that of a feeble bisinuate line 

 bulging out feebly and very narrowly in the middle. The clypeus 

 is strongly reflexed at the sides, very distinctly margined across 

 the front, feebly concave in front, its sides scarcely angulated 

 immediately in front of the eyes, its sculpture scarcely so coarse as
