202 SUBFAMILY x. CURCULIONINJB. 



VII. PACIIYPHANES Dietz, 1894. (Gr., ''thick"-]- "appearance.") 



Small but stout convex species having the beak strongly 

 curved; antenna? inserted two-fifths from apex, male, nearer the 

 middle, female; second joint of funicle longer than third, 4 7 

 very little wider; tibia* all with distinct spurs. The species are 

 usually listed under the name Pacl\y1ji<-liins Jek., to which they 

 were wrongly ascribed by LeConte. Four of the eight recog- 

 nized by Diet/ occurs with us. 



KEY TO EASTERN SPECIES OF PACIIYPHANES. 



a. Fifth elytral interval densely clothed with white scales nearly through- 

 out its length; first and second joints of funicle elongate, slender, 

 subequal in length. 275. LIXEOLATUS. 



<7rt. Fifth interval not conspicuously scaly; second joint of funicle dis- 

 tinctly shorter than first. (Fig. 65, h.) 



l>. Thorax distinctly narrower than the base of elytra, the latter usually 

 with a large median subbasal area of darker brown or blackish 

 scales; fourth joint of front tarsi much longer than third, 

 c. Scales of elytra white; scutellum not visible; form broader, more 

 robust; length 3 3.5 mm. 276. DISCOIDEUS. 



cc. Scales of elytra dirty yellow; scutellum distinct, small, glabrous; 

 form narrower, more slender; length 2 2.8 mm. 



277. CORPULENT! s. 



bit. Thorax at middle but slightly narrower than base of elytra, its disc 

 with two white stripes; scutellum distinct but very small; fourth 

 joint of front tarsi not longer than third. 278. AMCEXITS. 



275 (10,891). PACHYPIIAXES LIXEOLATUS Casey, 1892, 385. 



Oblong-oval, robust, convex. Black, feebly shining, the bases of third 

 and seventh intervals of elytra, and the fifth throughout most of its 

 length, densely covered with white scales; abdomen and thoracic side 

 pieces also densely scaly; antennae piceous, tibia? reddish-brown. Beak 

 rather slender, evenly curved, as long as head and thorax, male, three- 

 fifths as long as elytra, female. Thorax one-fourth wider than long, sides 

 broadly rounded, disc broadly constricted near apex, densely and finely 

 punctate. Elytra at base nearly one-half wider than thorax, humeri 

 prominent; sides subparallel on basal half, thence strongly converging to 

 apex; stria? rather fine, deep, their punctures elongate, indistinct; inter- 

 vals wide, flat. Length 33.5 mm. (Fig. 66, b.) 



Lake and Marshall counties, Indiana, scarce; May 30 July 

 15. Recorded from Illinois, Texas and Missouri. Easily known 

 by the dull black color, arrangement of scales on elytral intervals 

 and reddish tibiip. The punctures on the middle of thorax are 

 transversely ova 1 . 



276 (8548). PACHYPIIAXES DISCOIDEUS Lee., 1876, 169. 



Oval, robust, convex. Black, everywhere densely clothed with oval, 

 whitish and pitchy black scales, the latter forming a broad, irregular
