198 MEMOIRS ON THE COLEOPTERA 



There is no described species closely allied to this, as may be seen 

 by the structure of the antennal club and the minute sparse punc- 

 tures of the elytra. The punctures of the abdomen consist simply of 

 two lines, radiating backward from the base of each hair, inclosing 

 a few longitudinal rugulse a sculpture quite general in the genus. 



Cryptorhopalum piceum n. sp. More briefly oval than the preceding, 

 convex, shining and black above and beneath, the elytra throughout 

 obscure rufous, blacker basally; pubescence above obscure, not long or 

 close, shorter beneath and even finer, not closer and even less conspicuous; 

 head flattened on the front, finely, sparsely punctate, the ocellus large; 

 antennae dark brown, with its cavity not extending quite to the middle 

 of the prothorax, the club oval, its second joint only about three-fourths 

 as long as the first; prothorax as in the preceding in outline though rather 

 shorter and more transverse, the punctures sparser and still more minute; 

 elytra not more than a fourth longer than wide, slightly wider than the pro- 

 thorax and with more prominent humeral swellings than in bakeri, obtusely 

 rounded at apex; punctures fine and widely separated, but less so than 

 in the preceding, and with the outline of the punctures slightly pyriform; 

 sterna somewhat strongly but very loosely punctate and shining, the 

 abdomen rugosely sculptured in a manner somewhat similar to that of 

 bakeri; legs rufous. Length (9) 2.0 mm.; width 1.2 mm. California 

 (Claremont) , Baker. 



This is also a very distinct species which, according to the legend, 

 occurs in the blossoms of Eriogonnm fasciculatum; it is distinguish- 

 able at once from triste Lee., by its more abbreviated form and finer 

 and much sparser elytral punctures, among other differences such as 

 coloration, which however is not always stable. It may be placed 

 near caseyi Torre (affine \\ Csy.) ; it is more abbreviated than that 

 species and has a much more feebly sculptured abdomen. 



Cryptorhopalum floridanum n. sp.- Oval, moderately stout, convex, 

 shining, widest across the rather conspicuous humeral prominences, deep 

 black above, picescent beneath, the abdomen dull rufous; legs ferruginous, 

 the femora nubilously darker; pubescence moderate in length and nearly 

 black, extremely short beneath, sparse and inconspicuous; head strongly 

 but sparsely punctate, the ocellus feeble; antennae bright ferruginous, the 

 basal joint infuscate, the club broadly oval, with its second joint a little 

 smaller than the first, the suture rather coarse; cavity extending barely 

 two-fifths the length of the prothorax, the latter not twice as wide as 

 long, the converging sides evenly and moderately rounded, the lobe large 

 though narrowly truncate; punctures fine and widely separated; elytra 

 scarcely a fourth longer than wide, only two and one-half times as long 

 as the median line of the pronotum, the sides slightly converging and 

 broadly arcuate behind the humeral prominences to the rapidly rounding 

 and very obtuse apex; punctures shallow, rounded, not very fine and 

 separated by two to three times their diameters, the ground sculpture
