American Caraboidea 223 



The following species is much smaller, and, relatively, the pro- 

 thorax is not so large: 



Pristodactyla scolopax n. sp. — Body smaller and narrower, deeper 

 umber-brown in color, the under surface and legs nearly as in the pre- 

 ceding; general characters subsimilar; head not elongate, more than 

 two-thirds as wide as the prothorax, with more prominent eyes; antennae 

 nearly similar; prothorax almost similar but not paler at the sides, 

 which are straight and feebly oblique posteriorly, with the basal angles 

 more narrowly rounded and with more conspicuous puncture; side 

 margins rather less broadly reflexed; general features similar; elytra 

 narrower and still more elongate, only about a third wider than the 

 prothorax, the gradually rounded apex without sinus; striae, intervals 

 and two dorsal punctures nearly as in binaria; tarsi almost similar. 

 Length (cf 9) 7.8-8.7 mm.; width 2.8-3.1 mm. Colorado. Levette 

 collection. Nine specimens. 



Besides mollis and the two preceding, there are two other Alaskan 

 species which may be assigned to Pristodactyh, both having two 

 dorsal elytral punctures; one of these, Anchomenus lenis Mann., 

 from Kodiak Island, is said to differ from mollis in its larger and 

 narrower prothorax, more narrowed and more strongly reflexed 

 toward base, obliquely rounded basal angles and more elongate 

 elytra, these characters fitting the two here described better than 

 the recorded characters of mollis. According to a manuscript note 

 by LeConte, lenis, in fact, is said to be a Pristodactyla. 



The second species was named Anchomenus dulcis by Manner- 

 heim, and is from the Kenai Peninsula; it is said to differ from lenis 

 in its still more elongate form, longer and narrower prothorax, not 

 linearly but arcuately narrowed posteriorly, with less reflexed 

 margins and less obliquely truncate hind angles, and also in having 

 shorter elytra. LeConte does not seem to have seen this species. 



The following species resembles seminifa somewhat in general 

 form and size, but has the head and prothorax relatively smaller, 

 the elytra more opaque and the coloration very different: 



*Pristodactyla subopaca n. sp. — Narrow, elongate-oval, small in size 

 and moderately convex, deep black, the legs piceous-black; upper 

 surface highly polished anteriorly, the elytra rather densely opaque; 

 head barely at all elongate, fully two-thirds as wide as the prothorax, 

 the eyes well developed but only moderately prominent; palpi rufous; 

 antennae slender, fusco-testaceous, clearer basally, fully four-sevenths 

 as long as the body; prothorax very little shorter than wide, widest 

 before the middle, the sides moderately and subevenly arcuate through- 

 out the length and finely reflexed; basal angles obtuse and rather broadly
