•and tei'minates at the rounded median basal fovea, while in lacerta 

 •it is naiTOwei' and deeper, and terminates at the basal angles; this 

 character is comparatively constant. In lacerta the densely pubes- 

 cent spots referred to as a prominent character of inicleatuti, are also 

 visible and in nearly the same positions, but they are always feebler; 

 the length of lacerta is 4.0-5.0 mm.

The form of the body in this genus somewhat resembles that of 

 Coniontis, but is as a rule rather more broadly and evenly elliptical, 

 the prothorax being more strongly narrowed from base to apex. 

 The sculpture is stronger and denser, and the set^e, which are seldom 

 prominent and nearly always recumbent in Coniontis, here become 

 much denser and more erect, in this latter respect resembling those 

 of the aberrant Coniontis obesa Lee. The species are entirely 

 confined to the small island of Guadalupe, off the coast of Lower 

 California. 



Most of the material before me has been recently collected by 

 Mr. G. W. Dunn ; the series is very extensive, amounting to about 

 forty specimens, and indicates three species which may be distin- 

 guished as follows : — 



G 



Form broadly elliptical ; sides arcuate. 



Punctuation of elytra sparse, not muricate ; surface shiniufi; ; seta? fine, 



easily removable pillictlllata 



Punctuation of the elytra distinctly muricate ; set<e coarse, very persistent, 



always jjresent on the elytra muricata 



Form narrow, oblong ; sides parallel and nearly straight ; surface dull, densely, 

 coarsely muricate august ula 



C. anglistllla n. sp. — Oblong, moderately robust; sides parallel and 

 nearly straight ; color above dark brownish-ferruginous, beneath slightly 

 paler and more rufous ; legs concolorous ; lustre dull. Head slightly wider 

 than long ; median impression very small and nearly obsolete ; punctures 

 rather coarse, deep, very dense, sparser on the occiput ; a small median area 

 at the base impunctate. Prothorax transversely, strongly convex, fully twice 

 as wide as the median length ; sides feebly convergent from base to apex and 

 feebly, evenly arcuate ; apex broadly emarginate ; base nearly straight, except 

 at the sides where it becomes distinctly sinuate ; basal angles distinctly pro- 

 duced posteriorly, right when viewed laterally, not rounded, apical very 

 narrowly so ; disk very narrowly reflexed at the sides, coarsely, very deeply 

 and densely punctate, most densely so at one-fourth the width from the sides, 

 where the punctures tend to coalesce longitudinally, more sparsely so near the 

 edges. Elytra at base as wide as the prothorax ; sides parallel and nearly
