loo Memoirs on the Coleoptera 



was associated closely with maculicolle by that author, but the 

 two are by no means allied and the former species has been assigned 

 above to the genus Sericoda. The pronotal foveae are large, shallow 

 and formed partially by the reflexed margin as in the placidum 

 group. Maculicolle is a very isolated type of Agonum and without 

 doubt demands a separate name, at least of subgeneric weight. 

 The three forms in my collection may be known as follows: 



Body stout in form, very variable in size, convex, shining, the elytra 

 feebly alutaceous in the female; color pale flavo-testaceous, the 

 head more or less clouded, the central part of the pronotal disk and 

 ■ a large central elytral area blackish, the elytral plaga unevenly 

 sinuate antero-laterally; under surface dark rufous, with paler legs, 

 the abdomen in great part black; head not elongate, two-thirds as 

 wide as the prothorax, with moderately prominent eyes and short 

 and feeble to obsolete anterior impressions; palpi pale, the last 

 joint subequal to the third or slightly longer; antennae somewhat 

 longer than the head and prothorax, not very slender, the third 

 joint a little longer than the fourth; prothorax a third to nearly 

 half wider than long, the parallel sides evenly rounded and strongly 

 reflexed; basal angles broadly rounded, the apical only blunt to 

 broadly rounded; anterior impression angulate, feeble, the stria 

 fine; foveae large, feebly concave, formed partially by the reflexed 

 margin, finely and sparsely punctulate; elytra oblong-oval, broad, 

 barely one-half longer than wide, rather less than one-half wider 

 than the prothorax, the arcuate sides but little more arcuate basally; 

 apex gradually obtusely ogival, the sinus feeble but evident; striae 

 fine, smooth, grooved; intervals wide, varying from perfectly flat 

 to slightly convex, sometimes rather strongly so toward the sides, 

 having small scattered punctures toward the sides of the disk; met- 

 episterna rapidly narrowed, one-half longer than wide; tarsi very 

 feebly grooved externally, the anterior moderately thick in the male. 

 Length (cf 9) 8.7-10.7 mm.; width 3.2-4.6 mm. California (San 



Francisco to San Diego). Abundant maculicolle Dej. 



A — Coloration, lustre and general characters as in maculicolle but 

 more abbreviated, with the head relatively somewhat larger, the 

 prothorax more transverse and more widely explanato-reflexed at 

 the sides; elytra not one-half longer than wide; striae very fine; 

 intervals broad, flat, smooth, not evidently punctulate even 

 toward the sides, the third similarly with six distinct punctures. 

 Length (9) 9.2 mm.; width 3.8 mm. California (Guadalupe 



Island) guadalupense n. subsp. 



Body narrower and much more elongate, similar in coloration and lustre; 

 head two-thirds as wide as the prothorax, the eyes large but only 

 slightly prominent, the anterior impressions obsolete; surface feebly 

 rugulose laterally; palpi pale, the third joint fully as long as the 

 fourth, which is very gradually and finely pointed; antennae nearly 

 as in the preceding though slightly more slender; prothorax much
