RUTELIN^: 95 



sculpture toward the sides; prothorax much smaller in the male, 

 not more than three-fourths as wide as the elytra, four-fifths wider 

 than long, nearly as in ursina (cf), except that the converging sides 

 basally are not subsinuate but rounded and the obtuse basal angles 

 much more rounded; elytra subquadrate, as wide as long, with 

 rounded parallel sides and broadly, obtusely rounded apex, the 

 sculpture nearly as in ursina, the flanks below the humeri similarly 

 impressed; pygidium convex, very shining, with scattered fine 

 punctures becoming slightly coarser laterally. Length (cf) 14.5 

 mm.; width 8.5 mm. Southern California laevicauda n. sp. 



Basal bead of the pronotum but little more widely interrupted medially, 

 the pygidium as usual, finely and unevenly rugulose throughout, 

 though not densely. Color throughout as in lavicauda and tirsina, 

 except that the legs are deep black, polished and devoid of any form 

 of metallic lustre throughout, excepting a feeble blue-black tinge; 

 entire under surface deep and pure black, with long close, very 

 bristling pubescence, that of the upper surface long, plentiful, 

 bristling and conspicuous, close on the medio-basal parts of the 

 elytra but sparse and sublinearly arranged on the lateral parts of 

 the latter, which are deep red-brown in color; head as in Iccvicauda 

 but with the edges of the clypeus evenly and much more strongly 

 reflexed; prothorax not quite twice as wide as long, the parallel sides 

 evenly and strongly arcuate throughout, the basal angles well 

 defined, very obtuse but scarcely at all rounded, the apical right, 

 rather sharp; punctures coarse, well separated, smaller and more 

 confused near the sides, feebly impressed along the median line 

 before the middle; elytra much wider than the prothorax, a little 

 shorter than wide, very obtusely rounded at tip, parallel and 

 broadly arcuate at the sides; surface with rather strong punctures 

 and feeble oblique rugulosity suturally, the three or four impressed 

 discal lines evident and with small asperulate setigerous punctures, 

 also with a series along the lateral edge serrating the edge basally, 

 the ground punctures laterally very fine, sparse; pygidium finely, 

 unevenly rugulose, shining and with long sparse erect hairs; hind 

 tibiae but slightly enlarged distally. Length (cf) 12.7 mm.; width 

 7.8 mm. California (Coronado, San Diego Co.) . . . .brevis n. sp. 



Basal bead of the pronotum only visible in about lateral third; elytra 

 uniform tawny-yellow in color 6 



6 Body stout, convex, shining, herissate above and beneath with long 

 erect bristling ashy hairs, which are sparser and much less con- 

 spicuous on the elytra and there principally confined to the medio- 

 basal parts; head more than two-fifths as wide as the prothorax, 

 strongly and densely punctate, less coarsely so and densely rugulose 

 on the clypeus, which is flat, semicircular, with strongly, abruptly 

 and evenly reflexed edges, the rugulosity interspersed with slightly 

 coarser punctures; prothorax well developed but not as broad as in 

 ursina, nearly twice as wide as long, widest at the middle, where the 

 sides are obtusely subprominent, thence converging and more 

 broadly arcuate to apex and base, the basal angles very obtuse, 

 slightly rounded, the apical right and well defined; surface with the
