10(>f> FAMILY MI. f'KRAMBYCID.K. 



Subfamily III. LAMIINAE. 



The members of this subt'miiily are very numerous a in. I vary 

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

 in which almost all agree are the small, oblique groove of the outer 

 side of the front tibin:, the lack of side margins of the thorax and 

 the cylindrical pointed or spindle-shaped terminal joint of the 

 palpi. In the tribe M<tlnini 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 

 coxa 1 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 angles to the length of 

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

 forming an angle. The "cieatrix" is a sort of scar seen near the 

 tip of the scape or first antenna! joint in certain genera. 



The species generally remain stationary by day upon the trunks 

 and branches of trees, and often escape detection by the resem- 

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

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

 Their colors are, therefore, as a general rule less vivid than those of 

 the Cerambyeina 1 , the prevailing tints being brown and gray. 



The larva 3 resemble those of the Cerambyeina? 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 within the, enlarged front segment. These larva* differ, 

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

 destitute of legs. 



The principal literature relating to the North American forms 

 of the subfamily, aside from the general works on the family al- 

 ready cited, are as follows :
