California (San Bernardino). 



The four hind tarsi are much longer than the tibiae, the basal 

 joint of the posterior obconical and distinctly shorter and narrower 

 than the second, the latter large, as wide as long and fully as wide 

 as the third, which is not transverse but narrowly deeply emar- 

 ginate, the fourth joint is rather short and very slender. The type 

 is a male, having a long narrow impression near the base of the 

 abdomen.

Euchcetes || LeConte — Proc. Am. Phil. Soc, XV, p. 319. 



This genus was proposed by LeConte, unfortunately under a 

 name which had been employed several times before in zoology, for 

 one of the most remarkable curculionides thus far discovered. Its 

 aberrant nature was in fact only partially known to its author, 

 who makes no reference whatever to the mandibles. The general 

 habitus of the body, abdominal structure and conformation of the 

 mes-epimera, show that it is a normal member of the Barini, but 

 its rostral and mandibular characters indicate that it should be 

 widely isolated, forming with Plocamus a group or subtribe. 



The beak is extremely slender, cylindrical and strongly arcuate, 

 but becomes abruptly inflated and thickened behind the antennae, 

 the under surface of the dilated portion having a narrow deep 

 groove along the middle, which is gradually narrowed posteriorly 

 and confluent at base with a deep transverse constriction, extend- 

 ing upward at the sides just in front of the eyes, becoming gradu- 

 ally attenuated and extinct and not attaining the upper surface. 

 This longitudinal groove is but a remnant of the usual channel 

 formed by the confluent scrobes, and is far too narrow to receive 

 the antennal scape, the latter being free. The antennae are com- 

 pletely inferior in insertion and are situated between basal third 

 and fourth in both sexes, the scape rather thick, short and extend- 

 ing to the under surface of the head between the eyes, the latter 

 being normal and widely separated beneath. 



The mandibles are very short and thick, compressed, bent upward 

 and move in a nearly vertical plane as in Balaninus, the condyles 

 being contiguous above and received in broad deep fissures at the
