282 CURCULIONID.E. [LeConte. 



second joint of funicle a little longer than the third, which is about equal 

 to the fourth. Claws simple. Length 2 mm.; .08 inch. 



Two specimens, New York and Michigan ; three specimens, British 

 Ci>luml)ia; Crotch. The legs are testaceous in one, piceous in the others. 

 Tlie prosternum is broadly emarginate in front, and slightly concave, l)ut 

 without antecoxal ridges ; the front coxae are not widely separated. In the 

 preceding species the prosternum is more deeply emarginate and more con- 

 cave, though the front coxge are not more widely separated. 



3. P. cavifrons, n. sp. 



Of the same size and form as P. sulcicoUis, densely clothed with small 

 liale and dark scales. Beak as long as the head, stout, cylindrical, curved, 

 densely punctured ; front strongly concave between the eyes. Prothorax 

 wider than long, much narrowed in front, and deeply transversely im- 

 pressed; apical margin elevated, notched at the middle, with approximate 

 cusps ; posterior tubercles large, acute ; dorsal channel distinct. Elytra 

 with rows of small, distant, acute tubercles on the third, fifth, seventh and 

 ninth interspaces ; striae deep ; antennae and legs more or less testaceous ; 

 funicle with the second joint scarcely longer than the third or fourth. 

 Front coxfe not more widely separated than in the other species. Length 

 2.2 mm. ; .09 inch. 



California, at S. Buenaventura, Los Angeles, and Lake Tahoe; ]Mr. 

 Crotch. Though the front is deeply concave, and the upper margin of the 

 eyes prominent, there is no distinct orbit, such as is seen in Ccelogaster. 



CCELOG-ASTER Sch. 



This genus is easily distinguished from both Rhinoncus and Pelencon'is 

 by the eyes being inserted under distinct, acute, superciliary ridges or or- 

 bits, and being partly covered in repose. There are also important differ- 

 ences in the sternal pieces ; the prosternum is still more deeply and sud- 

 denly emarginate in front, so as to reach almost to the front coxae, which 

 also reach almost to the hind margin, and are more widely separated than 

 in either of the genera just named; the ridges in front of the coxa? limiting 

 the pectoral groove, are much stronger. The mesosternum is truncate be- 

 hind at the middle, and enters less into the formation of the middle coxal 

 cavities. The intercoxal process of the metasternum is therefore almost 

 square, and the middle coxae are more posterior than in the other genera. 



The beak and claws vary according to species; the funicle is 6-jointecl, 

 the first joint being stouter, and the others slender ; second and third elon- 

 gate ; 4-6 shorter, equal, scarcely thicker, club elongate-oval, pubescent, 

 acute at tip. 



Tliree species are known to me, of which the first is the type of the 

 genus. 



A. Beak slender, claws cleft ; eyes nearly covered in repose. 

 Black, mottled with whitish pubescence; elytra 

 with a common cruciform white mark at base; 

 antennae, tibiae and tarsi testaceous 1. Zimraermanni.
