VOL. XXXII. 



The fastigiuin of this species, as represented l\v a mature pair before 

 me, is deeply sulcate, but with the sulcus anteriorly closed, forming a 

 round pit, while in o-mtus it is open to the end, making the vertex nar- 

 rowly" clef t. The prosternum is unarmed in the two specimens before 

 me. Ovipositor of the adult quite strongly curved upward, nearly 



as long as the posterior femora 

 and apically armed both above 

 and below with about two dozen 

 acute teeth. 



The measurements of an adult 

 pair in the U. S. National Mu- 

 seum are as follows:

 the l)asal joints of the antenna\ Pronotum with rather feebly clejisydral disk, which 

 is considerably more than half as long again as broad, broadest but little behind the

 of the pronotum, the lateral carinte not elevated on the prozona, on the metazona a 

 little elevated but blunt; hind border margined, broadly rounded; median carina 

 feeble, subequal, percurrent; the whole disk uniform castaneous, transversely ])ecti-
