150 AMERICAN COLEOPTERA. 



(ilaws with a moderate tooth. Length 2-2.5 mm.; .08-.10 inch. (PI. V, figs. 

 3 and 3(f). 



%. Sutural tips only slightly more rounded than in the 9; fiont and middle 

 tibiae with a very short mucro. 



9 . Beak slightly longer; sutural tips scarcely rounded ; tibise unarmed. 



Hab. — Pacific Coast, from Oregon to San Diego ; also found in 

 Utah (Knaus). 



A not uncommon species throughout tlie region indicated, and one 

 which there is no possibility of confu.sing with any other. Only 

 one other species — opacicolle — is known with similar tibial armature, 

 and this is readily distinguished by the dull black surface, more 

 elongate form and slender beak. 



Cribricolle was described from a single specimen taken at San 

 Francisco and was in common with many other species, including 

 several species of Apion, recorded under a given number in one of 

 Dr. LeConte's note books. Through some mischance or other there 

 is now no specimen in the LeConte cabinet bearing either this 

 number or name in Dr. LeConte's handwriting, and we are there- 

 fore forced to depend upon the description for an identification of 

 the species. In his synopsis of the genus Frof Smith uses this 

 name for sundry examples of Section I, the majority of which are 

 the species here regarded as melanarium, and none of which are 

 from California. Moreover, as Prof. Smith had the LeConte mate- 

 rial, and in his description of cribricolle does not give California 

 in the list of localities, it seems certain that he too did not see the 

 original type. After a careful study of the original description I 

 am forced to conclude that LeConte really had in hand an example 

 of the species afterwards described by Smith as brevicolle, a species 

 which is not rare about San Francisco, and which corresponds very 

 well with LeConte's description. 



64. A. porcatiiin Boh. — Very robust, black ; pubescence very sparse, fine 

 and inconspicuous. Beak moderately stout, minutely reticulate and punctate 

 throughout, a confluent line of punctures over the insertion of the antennse. 

 First joint of antennae as long or a little longer than the next two, second reach- 

 ing the eye. Front not or very feebly sulcate, with two lines of punctures which 

 tend to coalesce ; eyes moderately prominent. Prothorax wider than long, 

 widening to the middle, thence subparallel to the base, before which there is a 

 slight sinuation ; punctuation coarse, moderately dense, a foveate line at base. 

 Elytra one-fourth longer than wide; humeri strong; sides slightly diverging to 

 beyond the middle; intervals strongly convex, but little wider than the striae; 

 legs moderate; claws armed with a strong tooth. Length 2.2-2.6 mm.; .09 .10 

 inch nearly.
