COLEOPTERA. 191 



beak very long and slender, n<'arly as long as the elytra and fully one-third 

 longer than the head and pronotum together, cylindrical except at the tip 

 where it is dilated and flattened ; mandibles very conspicuous, tridentate 

 without, sparsely truncate at tip, and having within two minute teeth near 

 the tip ; between them on the apex of the beak are two porrected tubercles ; 

 surface strongly rugulose or longitudinally channeled, the channels con- 

 fusedly coalescing at the base, above there is a longitudinal carina deeply 

 canaliculate along the crest; sides of the head finely rugulose in the form 

 of long vertical crowded folds ; antennae three-fourths as long as the beak, 

 slender, inserted at one-third the length from the eye, second joint long and 

 slender, miich longer than the first, very slightly longer and thicker than 

 the third, club abrupt, not very compact, joints almost equal in length and 

 slightly longer than wide. Prothorax as long as wide, widest at one-third 

 its length from the base ; sides feebly arcuate, more strongly so near the 

 base; apex and base equal in length, but very slightly shorter than the 

 greatest width ; disk sub-cylindrical, transversely and very feebly impressed 

 at the anterior fourth, very coarsely closely and deeply punctate, intervals 

 about one lialf as wide as the punctures, convex and polished ; sides of the 

 punctures irregularly and finely indented. Elytra widest at two-thirds the 

 length from tlie base where they are five-sixths wider than the pronotum ; 

 humeri prominent, rather rounded ; sides behind them feebly and broadly 

 sinuate ; disk rather abruptly and broadly rounded behind, more than one- 

 third longer than wide, very convex toward tij), flat or very feebly impressed 

 above and near the base, highly polished, punctato-striate ; striae feebly 

 impressed, punctures large, very deep, close and almost perforate, intervals 

 three times as wide as the punctures, feebly convex and finely undulated. 

 Abdomen transversely and feebly rugulose. Legs very long and slender ; 

 tibiae fimbriate at tip with short nearly equal spinules ; claws robust, dis- 

 tinctly toothed or cleft within at one-half their length from the base. Length 

 (exclusive of beak) 2.8 mm. 



Calitbrnia, 1. 



The contrast between the very coarsely and deeply punctate pro- 

 notum and the finely and vertically rugulose or strigilate sculpture of 

 the sides and under surface of the head is one of the greatest wliich 

 I have observed in two adjoining surfaces of the same insect. I 

 cannot see any species to which it can be allied, but it may for the 

 present be placed immediately after hirtas Oliv., from which it differs 

 by its more dense pronotal punctuation, and in the elytral intervals 

 not being serially punctulate ; it also appears to have a much longer 

 beak. 



AlVTHOXOMUS Germ. 



A. nioleCUlUS n. sp. — Form rather robust. Black throughout, an- 

 tennae piceous toward tip, paler and brownish-testaceous toward base, legs 

 black, tarsi very slightly paler, piceous,. upper surface covered not very 

 densely with small elongate cinereous scales which are more dense beneath,
