1060 FAMILY LII.J — nERAMBYCID^. 



Subfamily III. LAMIINAE. 



The members of tliis suhfiauily are vciy numerous and vary 

 greatly in size, color and general appearance. The three characters 

 in which almost all agree are the sniall, ohlique groove of the outer 

 side of the front tibia, the lack of side margins of the thorax and 

 the cylindrical pointed or spindle-shaped terminal joint of the 

 palpi. In the tribe Methiini alone the tarsal grooves are absent. 

 In addition the front of the head is vertical, so that, viewed from 

 above, the face cannot be seen and is usually large and flat; front 

 coxa3 rounded, never transverse, the cavities rarely open behind; 

 ventral segments always five. The tarsal claws are either "divari- 

 cate," i. e., extending in a plane at right a,ngles to the length of 

 the last tarsal joint, or "divergent," not in the same plane but 

 forming an angle. The "cicatrix" is a sort (if scar seen near the 

 tip of the scape or first antennal joint in certain genera. 



The species generally remain stationary by day upon the trunks 

 and branches of trees, and often (>sca,pe d(>t(>ction by the resem- 

 blance which they Ixvii-, in the hues and sculpture of their bodies, 

 to the color and inequalities of the bark on which they repose. 

 Their colors arc, therefore, as a p-eneral nde less vivid than those of 

 the CerambyeinaB, the prevailing tints h(ung brown and gray. 



The larvEK resemble those of the Cierambycina' in being of a 

 nearly cylindrical form, but a little tapering behind, and consider- 

 ably swollen at the front extremity, with a small head, which is 

 retractile wifhin the enlarged front seuiiient. These larvie differ, 

 however, from those of nearly all other Longicorns in being wholly 

 destitute of legs.
