COLEOPTERA— TENEBRIONID^. 483 



radiating from the head ia the phxte do not belong to the specimen but he 

 at a slightly higher level, except the proximal half of the one lying next the 

 body, which is the basal joint of the antennae, and which before careful study 

 was taken for a beak, and the insect therefore placed among the Hemiptera. 

 The head and thorax have the form and attitude of the Rhipiphoridse ; the 

 eye is oval, twice as long as broad ; the basal joint of the antennae enlarges 

 slightly from base to apex and is nearly as long as the head ; an ineffectual 

 attempt was made to uncover the parts beyond and reveal the structure of 

 the remaining joints. Tlie head and thorax are delicately scabrous rather 

 than punctate, or punctate with the punctures run together transversely in 

 an irregular manner. Tlie elytra are almost as long as the body, three and 

 a half times as long as their basal breadth, the sutural margin perfectly 

 straight until the rounding of the extreme apex begins, the outer margin 

 broadly sinuous, the elytra shortly beyond the base diminishing rather 

 rapidly in widtli as far as the middle, then subequal to just before the tip, 

 which is half as broad as the base, strongly rounded, almost equally on each 

 side ; the tip has been uncovered since the plate was made, and is in no 

 sense pointed, but the inner side is subrectangular though rounded ; the 

 surface is punctured, not deejjl}', the punctures separated by considerably 

 more than their own diameter ; the outer boi'der is finely marginate, at least 

 in the basal half The wings are ample, exceeding when closed the length 

 of the abdomen, and wlien expanded surpassing by one-fifth the elytra ; 

 they show at least four principal veins radiating from the base, some of them 

 distinctly forked, and none showing marks of a transverse fold. 



Length of body, 9.75"™ ; elytra, 6™".
