OERAMBYCIDAE. 305 



Group III. — Anaglypti. 



The head is also large, and the front long, and quadrate; the 

 antenna^ slender, moderately long, with the joints 3-5 sonietinies 

 spinose at tip; the prothorax is not narrowed in front, bnt always 

 much constricted behind ; the elytra are freciuently gibbous at 

 the l)ase, and declivous at tip, and sometimes have transverse 

 ivory bands. The episterna of the metathorax are narrow, and 

 the opimera are scarcely produced over the angles of the 1st 

 ventral ; the intercoxal process is acute. The legs are moderate 

 in length, and the thighs somewhat strongly clubbed, but not 

 spinose at tip; the 1st joint of the hind tarsi is less elongated 

 than in the other groups. The mesonotum is not punctured at 

 the sides, and is covered with very fine stridulating lines. 



In some of the genera the middle coxal cavities are nearly or 

 entirely closed externally, but, as in other portions of the series, 

 the transition is accomplished by such slight gradations that the 

 character seems to have little value. 



Seoond joint of anteiinse equal to 4tli ; 



Antennae not spinose, elytra without ivory si)ots. Microclytus. 



Second joint of antennse short, 3d longer than 4t]i ; 

 Elytra without ivory spots ; 



Eyes oblique, emarginate. Cyrtophorus. 



Eyes entire, rounded. Tillomorpha. 



Elytra with a transverse ivory hand. Euderces. 



Microclytus is founded upon C. rjazcUnla TTald. a species of 

 the Middle States, having entirely the form and coloration of the 

 European Anaglyptus mjjsficvs, but smaller, and differing essen- 

 tially by the 2d joint of the antenna3 being fully half as long as the 

 3(1, and scarcely shorter than the 4th joint; the flying hairs are 

 jieculiarly long and numerous; the eyes are oblique, emarginate 

 above, and pointed bcihind, as if the usual deeply emarginated 

 form had l)een shortened by the obliteration of the upper part. 

 The same form is seen in Cyrtophorus verrucosus, but less acute 

 at the upper angle. In Tillomorpha geminata (Ilald.) the eyes 

 are oval, not at all emarginate, the upper part being absent; and 

 in Euderces they are entirely divided, the lower part being emar- 

 ginate, acutely pointed above, and the upper part small, distant, 

 and oval.*
