METRODORIN^. 



In general we find the body is little or not at all rugose, 

 of (|uitc large size, the pronotum not strongly prolongate, but 

 rather widely subulate. The head is not crowded into the 

 pronotum so far as the eyes; in general it is more or less com- 

 pressed backward, the vertex being nearly always higher than 

 the disk of the pronotum; the eyes are large and projecting; 

 the antennae are of variable length and filiform, and inserted 

 in front of the anterior inferior border of the eyes; the superior 

 ocelli are placed between the ej'es and nearer their anterior 

 border; it is between them that the frontal costa divides into 

 two diverging branches forward, although separated nearly 

 always by a narrow sulcus. The pronotum is depressed above, 

 always truncated in front and prolonged backward, or in some 

 it may not reach the extremity of the abdomen, in the others 

 well [jrolonged beyond and ending in a sharp [joint. The 

 median carina is scarcely elevated, offering sometimes small 

 cratiform elevations; the humeral angles obtuse; the lateral 

 lobes having their posterior angle directed outward as a lobe, 

 obliquely truncate behind and rather angular. The elytra and 

 the wings have the ordinary form, except in the genus Platy- 

 thorus, in which they are both wanting; in C/iiriqiiia the elytra 

 are minute and elongate, while in Qtuinba the elytra are 

 lanceolate. The legs are generally rather long, the posterior 

 tibiae somewhat spinose, the terminal s])urs unequal, the tarsi 

 narrow at the first segment, which equals the third in length, 

 or nearly so. The valves of the ovipositor are serrulate- 

 acute at the extremity and denticulate along the borders.
