American Caraboidea 215 



arcuate, feebly, anteriorly converging sides becoming more parallel 

 and straighter posteriorly, the basal angles but little more than 

 right and rather sharp, not even blunt at tip; anterior and posterior 

 impressions both evident though feeble; sides narrowly but strongly 

 reflexed, becoming gradually much broader and flat posteriorly; 

 basal foveae elongate and feebly impressed, much more evident 

 than usual; elytra narrower and less convex than in the preceding, 

 three-fifths longer than wide, about a third wider than the pro- 

 thorax, of the usual outline; striae rather fine but much less so than 

 in the preceding and less sharply defined, not deeper on the declivity; 

 intervals flat, the subscutellar puncture similar; dorsal punctures 

 four to five; anterior tarsi of the male rather moderately dilated, 

 much less so than in giiadalupensis. Length (cf ) 8.8 mm.; width 



3.35 mm. Guadalupe Island insularis n. sp. 



7 — Prothorax large, nearly half as long as the elytra and scarcely nar- 

 rower, with distinct and only narrowly blunt right basal angles; 

 strial intervals feebly and confusedly punctate, less evidently in the 

 female. Body subparallel, rather convex, bright testaceous, the 

 elytra black, with pale reflexed margins; surface polished through- 

 out (cf ) or with the elytra very faintly alutaceous (9 ); head four- 

 sevenths as wide as the prothorax, barely longer than wide, with 

 well developed convex eyes; antennae moderately slender, filiform, a 

 little longer than the head and prothorax; last palpal joint distinctly 

 longer than the third; prothorax but very slightly wider than long, 

 the sides arcuately converging in apical, .parallel and straight in 

 basal, half; sides moderately reflexed, becoming broadly sub- 

 deplanate posteriorly only in the female; stria fine, biabbreviated, 

 the transverse impressions obsolete, the foveae barely traceable; 

 elytra one-half longer than wide, gradually obtusely ogival behind 

 the middle; striae only moderately fine, more deeply impressed 

 internally and apically in the male; intervals (cf ) just visibly 

 convex or (9) flat; dorsal punctures unusually distinct, two to 

 three in number, the subscutellar puncture distinct; three basal 

 joints of the anterior tarsi (d^) very distinctly dilated, the fourth 

 abruptly very narrow. Length (c^ 9) 7-5-8.5 mm.; width 3.2-3.4 

 mm. California (Hydesville, Valley of Eel River, Humboldt Co.). 



Three examples grandicollis n. sp. 



Prothorax relatively smaller, always distinctly narrower than the elytra 

 and less than half as long, the basal angles evidently and sometimes 



rather broadly rounded; strial intervals not punctulate 8 



8 — Color pale and bright rufo-testaceous, the elytra dark as usual. 

 Body moderately narrow and elongate, the elytra but feebly dilated; 

 lustre shining throughout (d^), or with the elytra more or less 

 opaculate ( 9 ) ; head scarcely longer than wide, very little more than 

 half as w'ide as the prothorax; antennae moderately slender, some- 

 what attenuate distally, not quite half as long as the body; last 

 palpal joint as long as the third and not thicker, obtusely pointed; 

 prothorax only a fifth or sixth wider than long, and with the sides 

 arcuate and converging apically, parallel basally, reflexed, becoming 

 deplanate basally; foveae feebly impressed; impressions obsolete,
