58 MEMOIRS ON THE COLEOPTERA 



elytra three-fourths longer than wide, oval ; the side margins concolorous, 

 the surface convex, with sculpture somewhat as in tcedatus, not regularly 

 striiform however but much confused, granular on the flanks, the foveee 

 nearly similar. Length 19.5 mm.; width 8.0 mm. A single male from 

 an unrecorded locality but probably taken in Colorado. 



Differs from tcedatus, of which group it is a member, by the very 

 broad prothorax and confused elytral sculpture, in which, however, 

 the tcedatus type can be traced very readily. 



Carabus franciscanus n. sp. Sculpture, coloration and lustre as in 

 tcedatus, the body much more elongate and with the elytra deplanate 

 toward the humeri and not convexly declivous; head not quite so large and 

 with radially different sculpture; last joint of the maxillary palpi obtri- 

 angular and longer than the preceding joint; surface with the lateral 

 impressions not short and anterior as in tcedatus but very deep and pro- 

 longed posteriorly to the line of the middle of the eyes, gradually ex- 

 panding and very coarsely, strongly, vermicularly rugose, the rugae 

 throughout its length extending inwardly nearly to the median line of 

 the vertex and front, which is elevated in a ridge-like manner, with the 

 summit of the ridge deeply canaliculate except anteriorly; neck strongly 

 rugose, smooth medially; antennae less than half as long as the body, 

 tapering distally; prothorax as in tcedatus but relatively larger and but 

 very little wider than long, three-fifths as wide as the elytra, the latter 

 much more elongate and less convex, gradually declivous laterally, 

 still more gradually basally, in outline and sculpture nearly as in tcedatus, 

 the sides straighter basally, the side margins much more broadly reflexed; 

 hind tarsi about as long as the tibiae. Length 21.5 mm.; width 8.5 mm. 

 California (coast region near San Francisco). A single male. 



At first I thought that this species might be regarded as a sub- 

 species of tcedatus, but on examining the structure of the head and 

 the flanks of the elytra, especially in the vicinity of the humeri, 

 it becomes evident that it has no such close relationship, though a 

 member of the tcedatus group. 



Carabus taedatus ssp. montanicus nov. Similar to tcedatus in general 

 form, sculpture and coloration but larger, somewhat stouter and with 

 relatively slightly larger head and prothorax; head nearly similar, the 

 vertex broadly almost smooth, with a few longitudinal folds near the 

 eyes; antennae perceptibly longer and stouter; prothorax similar in outline 

 and sculpture but with distinct punctures scattered medially, similarly 

 dense laterally and basally; elytra similar in sculpture and convexity 

 throughout, but a little broader, nearly three-fifths longer than wide, 

 one-half wider than the prothorax; abdomen rufo-piceous. Length 

 21.5 mm.; width 9.0 mm. Idaho (Coeur d'Alene). A single male 

 example. 



The type of this species was sent to me under the name oregonensis
