HARPALINJE 201 



much more southern in habitat, deep shining black throughout; 

 legs dark rufous, the antennae moderately thick, somewhat obscure; 

 head short, nearly as in piceus but with the coarse, deeply perforate 

 punctures closer, wanting in a large central area; prothorax nearly 

 as in piceus but with the sides rather less converging posteriorly, the 

 basal angles very obtuse and evidently rounded, the punctures much 

 more numerous and slightly coarser; elytra nearly similar but larger, 

 more distinctly wider than the prothorax, the intervals nearly flat, 

 with the punctures relatively not quite so large, similarly unevenly 

 spaced in the series but with both series of all the intervals nearly 

 even; under surface and hind tarsi almost as in piceus. Length 

 (cf 9 ) 8.5-9.5 mm.; width 3.2-3.7 mm.; California (San Diego and 



on San Clemente Island). Fifteen examples australinus n. sp. 



A Similar to australinus but still larger and rather stouter; head and 

 prothorax nearly similar, the punctures of the latter less close-set 

 as a rule, the basal angles obtuse and rounded; elytra nearly as in 

 australinus throughout, the series almost even, the general surface 

 very shining in both sexes; abdominal and prosternal punctures 

 sparser; hind tarsi nearly similar and a little shorter in the female 

 than in the male. Length (d" 9 ) 8.5-11.0 mm.; width 3.2-4.0 

 mm. Guadalupe Island. Fifteen examples. . .insularis n. subsp. 

 Body smaller than in either of the two preceding forms and somewhat 

 less convex, very pale testaceous in color throughout in the type, 

 which is doubtless immature, shining; head fully two-thirds as wide 

 as the prothorax, with sparse and very irregularly distributed punc- 

 tures, coarse laterally, smaller medially; prothorax only about a 

 fourth wider than long, the sides more rounded anteriorly than in 

 piceus and rather more converging basally, though otherwise nearly 

 similar and with obtuse and rounded basal angles, but more sparsely, 

 less coarsely punctate, with the punctures in the feebly subimpressed 

 basal foveae coarser and closer, the surface between this area and the 

 sides more narrowly and strongly convex; elytra nearly as in piceus 

 but with finer punctures of the series, the latter nearly regular but 

 loose ; punctuation of the under surface nearly as in piceus, the anterior 

 tarsi (cf) rather less broadly dilated, the hind :arsi nearly similar. 

 Length (cf) 7.0 mm.; width 2.5 mm. Arizona. A single example. 



decoloratus n. sp. 



The two principal groups in this genus are very clearly defined 

 and have somewhat the nature of subgenera. The species are 

 much more closely allied among themselves in the piceus than in 

 the more diversified dilatatus section. There are undoubtedly a 

 considerable number of forms closely allied to piceus, and I have 

 ventured to define a number of them above, but have been unable 

 to identify any of them with villosus or irregularis of Motschulsky, 

 the above synonymy being that of Horn; parallelus of LeConte is 

 however typical piceus. D. pallidus Mots., is Agonoderus rugicollis
