height, where it suddenly and a little obliquely drops to a level with 

 the anterior edge. The lower apical half of the disc of the pronotum 

 is nearly flat, and provided with several oblique carina^, which extend 

 from the well-marked nearly equal and smooth median carina to the 

 lateral edges. The anterior margin at middle straight, the apex is 

 sharply acuminate and extends little, if any, beyond the apex of the 

 valves of the ovipositor. The gibbosities are chiefly confined to the 

 lateral lobes anteriorly and below the lateral carinae. The lobes of 

 the carinae of the anterior and middle femora are less well-defined 

 than in reticulatus, especially is this true with reference to the superior 

 ones. Front, frontal costa, and vertex about normal for the 

 genus. 



General color dark brunneo-fuscous, varied with pale testaceous and 

 dull cinereous. Anterior and middle tibiae fasciate, the apical portion 

 of the tarsi infuscated. Hind femora with their apical half and the 

 tibiae largely testaceous, marmorate with browns. Apica' depressed 

 portion of the disc of the pronotum pale testaceous Apical four or 

 five joints of the antennae pallid, the middle ones infuscated, while 

 those at the base are more or less varied with testaceous. Dorsal 

 carina of the pronotum alternately pallid and fuscous. 



Length of body, 9 , 6.5 mm.; of pronotum, 6 mm.; of hind femora, 

 4 mm.
