CARABID.E 33 



prominent Lee. Subgracilis was when described represented by 

 the male alone, the female also is now at hand; it agrees thoroughly 

 with the male in general form and habitus but is much larger; 

 it is a narrower, more elongate and polished species than pere- 

 grinator and has a distinctly smaller head, showing that it belongs 

 with the prominens series. 



Calosoma semilaevis ssp. davidsoni nov. General habitus, lustre 

 and sculpture as in semilcevis but more elongate, with the prothorax 

 much smaller, less transverse and having the parallel sides much less 

 rounded; elytra a little smoother and more shining. Length (cf 9 ) 

 21.0-24.0 mm.; width 9.4-10.5 mm. California (Alameda Co.). 



This is the variety alluded to in my previous article on Calosoma 

 (Mem. Col. IV, p. 65) ; its appearance is very distinct from that of 

 semilcEvis and it should be designated by name ; it is named in honor 

 of Dr. George Davidson. Semilcevis is common near San Francisco; 

 there is one example in my series which does not seem to differ, 

 marked Guadalupe Island. 



Subfamily PTEROSTICHIN^E. 

 Adrimus Bates. 



The following species seems certainly to belong to this genus, 

 which is disseminated in very moderate number from the Amazon 

 regions to Mexico: 



*Adrimus panamensis n. sp. Moderately stout and convex, strongly 

 shining throughout, the elytra with evident iridescent lustre, piceous- 

 black in color, rather paler beneath, the legs throughout and the palpi 

 pale flavo-testaceous; head smooth, nearly three-fourths as wide as the 

 prothorax, with large and prominent eyes, the foveae impressed and 

 oblique, the palpi very slender; antennae slender and filiform, rather 

 more than half as long as the body, feebly infuscate, clearer testaceous 

 basally; prothorax about a third wider than long, widest before the 

 middle, the sides broadly, evenly rounded, slightly converging basally, 

 becoming feebly sinuate at the hind angles, which are finely acute and 

 prominent; base transverse, beaded only laterally, a little wider than the 

 apex, which is moderately sinuate, with rather distinct angles; surface 

 smooth, finely reflexed at the sides, without trace of transverse impressions 

 and extremely minutely, sparsely and feebly punctulate throughout at 

 base, the stria very fine, not entire, the foveae elongate, narrow, linear 

 and moderately impressed; elytra barely two-fifths longer than wide 

 and about one-half wider than the prothorax, parallel, with rather arcuate 

 sides and rapidly ogival apex, the sinus feeble, the fold evident; striae 

 fine but rather deeply impressed, finely, closely and very evenly punctate,
