CERAMBYCIDAE. 321 



Tribe XII. AGALLISSINI. 



A tribe composed of a single genus Agallissus Dalman (Cryp- 

 topleura Lee.) which is remarkable for having the epipleurae 

 strongly sinuated near the humeri. Head small, front short, ver- 

 tical in A. clerinus, quadrate, oblique in A. gratus ; eyes finely 

 granulated, deeply emarginate ; antennal tubercles not elevated, 

 antennae slender, shorter than the body in both sexes, finely punc- 

 tulate, and sericeous, llth joint feebly appendiculate ; mandi- 

 bles small, stout, acute, genae moderately short ; mentum trans- 

 verse, of the usual form, entirely corneous ; palpi short, equal, not 

 dilated. Front coxae small, not prominent, cavities rounded, 

 open behind ; middle coxal cavities angulated externally, meso- 

 sternum suddenly declivous in front. Epimera of metathorax 

 very wide in front, gradually narrowed behind ; ventral segments 

 slightly decreasing in length ; legs short, slender, thighs not cla- 

 vate, spurs small, 1st joint of hind tarsi but little longer than 

 the 2d. 



The prothorax is rounded on the sides, not transverse, the elytra 

 are wider at base than the widest part of the prothorax, and the 

 humeri are rather prominent, as in many Lepturidse. The scu- 

 tellum is obtusely rounded behind, the mesonotum is smooth and 

 polished, with a large, very fine stridulating plate. Flying hairs 

 of moderate length are seen over the general surface of the body, 

 and on the legs. 



Two species occur in our fauna, A. gratus (Cryptopleura grata 

 Hald.) from Texas, and Northern Mexico, shining black, sparsely 

 punctured, with the elytra narrowed behind, truncate and finely 

 serrate at tip, ornamented with yellow spots, of which the basal 

 pair are elongate ; and A. clerinus from Florida, opaque black, 

 very coarsely and densely punctured ; prothorax red, with faintly 

 indicated dorsal smooth spots; elytra parallel on the sides, 

 rounded at tip, with a round basal spot, and two broad trans- 

 verse bands bright scarlet. Length lo mm. 



I consider this as the nearest approach made by the genuine 

 Cerambycidae to the Stenocorus group of Lepturidae. It is, how- 

 ever, quite an isolated form, and the two species above mentioned 

 should probably be regarded as distinct genera.
