uf the IjitiM'sil rjiriiiju*: an oblique einieiforrii yellow dasli, the apex in 

 fn»nt and above, follows the riiljie of the nietathoiaeie episterna, nuir- 

 pine<l on either sifle by an ecpial pieeoua belt. The dorsal Held of the 

 tejjinina is of the same color as the disk of the j>ronotuin, or oerasionally 

 a little paler, while the lateral tield is nearly always nmeh darker 

 brown, the diseoidal area marked by <lashes of blaekish fuscous, which 

 occasionally sulVuses nearly the whole of the lateral field. The hind 

 femora are twice barred with blackish alxjve, and have more or less 

 bhu'kish fuscous on their outer face; while the under portion of the 

 femora is yellowish. an<l the hind tibiae red with bhicktipped spines,

 trianjuuiar stri|»es posteriorly; vertex tumid, elevated above the prono- 

 tum, the interspace between the eyes not very narrow, sli«;htly broader 

 than the first antennal Joint; fastijjium strongjly declivent, broadly 

 snlcate anteriorly, moie deeply in the male than in the female; frontal

 depressed at the ocellus, seriately i)unctate at the sides; eyes rather
