Coleopterological Notices, III. 67 



very densely punctate, laterally toward the apex with small, distant, feebly 

 elevated tubercles in single series on each. Abdomen finely, somewhat densely 

 punctate ; metasternum but slightly shorter than the first ventral segment ; 

 mesosternum long and depressed in front, rather narrowly separating the 

 coxae, feebly declivous and slightly impressed before the coxae, the process be- 

 coming horizontal behind ; pros tern al process not at all prominent posteriorly. 

 Legs moderately long, the tibiae rather strongly enlarged from base to apex, 

 the anterior tarsi rather broadly dilated in the male, posterior short with the 

 basal joint equal to the next two and much shorter than the last. Length 

 8.0-9.0 mm. ; width 3.2-3.3 mm. 



California (San Diego). Dr. F. E. Blaisdell. 



The two specimens before me are both males, and have the intro- 

 mittent organ rather broad throughout, abruptly and sharply acumi- 

 nate at apex, and with the upper surface deeply and longitudinally 

 excavated, the excavation extending almost to the apex; in bachei 

 it is finely but less abruptly acuminate, and the upper surface is 

 finely, longitudinally subcarinate near the apex, the excavation 

 being very feeble and much less apical. The form of blaisdelli is 

 considerably shorter and the prothorax is very much more trans- 

 verse. 



H. discipilla n. sp. — Evenly elongate-oval, strongly convex, glabrous, 

 moderately shining, the elytra alutaceous ; upper surface dark castaneous, 

 beneath paler, rufescent ; legs and antennae rufous. Head coarsely, not 

 densely punctate, the punctures scarcely at all longitudinally confluent, 

 slightly finer anteriorly ; eyes prominent ; antennae short, but slightly longer 

 than the head and prothorax, joints four to eight increasing in length, rather 

 slender, obconical, nine to eleven thence gradually shorter and more dilated, 

 the last obliquely oval and not longer than the tenth, third one-half longer 

 than the fourth. Prothorax nearly one-half wider than long, the apex rather 

 distinctly narrower than the base, both subtruncate or extremely feebly arcu- 

 ate ; sides strongly evenly arcuate ; apical angles broadly obtuse and slightly 

 rounded, basal extremely obtuse and widely rounded ; marginal bead very 

 fine but distinct throughout the length ; disk not very coarsely, rather densely 

 punctate, the punctures sparser in the middle, with scarcely any tendency to 

 coalesce longitudinally toward the sides. Scutellum broadly triangular, short, 

 coarsely, rather densely punctate. Elytra oblong-oval, about three times as 

 long as the prothorax, and, in the middle nearly one-third wider than the 

 latter, twice as long as wide, gradually ogival behind ; sides parallel, broadly 

 arcuate ; humeri obtuse, exposed at base ; disk with very fine, entire unim- 

 pressed series of fine unevenly spaced and generally more or less linear punc- 

 tures, the intervals flat, minutely, sparsely, confusedly punctate, each with a 

 single widely spaced series of very small tubercles, which are rather indistinct 

 toward the suture. Abdomen finely, sparsely punctate ; sterna nearly as in 

 blaisdelli. Legs rather long, very slender. Length 7.0 mm. ; width 2.9 mm.
