Head : Vertex broadly rounded with transverse carina at 

 anterior extremity, the part of vertex dorso-caudal of this 

 region rugose, remainder faintly punctulate. Clypeus small, 

 transverse ; paraclypeals rovmd triangular. Labium broadened 

 and bilobed distally. Maxillae broad, maxillary palpi large, 

 trapezoidal, divided into a medio-caudal and latero-cephalic 

 part. Antennge broad for the fii'st half and reaching to the 

 tip of the first leg-cases, deeply sulcate longitudinally for 

 two-thirds of their length, transversely striate over their 

 entire length. Second leg-cases reaching only to just below 

 the first leg-cases. Wing-cases extending ventrally to half 

 the width of the 3rd abdominal segment. Pronotum with 

 anterior edge sinuate, surface rugose. Mesonotum large, 

 anterior third sharply declivous, posterior two-thirds straight, 

 sub-parallel to the ventral side, Avith a fine median longitu- 

 dinal groove, surface finely transversely striate. Humeral 

 angles broad, rectangular, hind edge of wing-cases straight, 

 dorso-lateral angle only slightly rounded. Metanotum short, 

 striato-punctulate ; hind wing-cases broadly visible to the 

 posterior edge of the second abdominal segment (text-fig. 9, 

 A, c, e). Abdominal segments on dorsal aspect transversely 

 striate, shiny ; posterior declivities matte, granulate, broadly 

 visible from 2nd to 8th segment. Segments 3 to 5 bear a row 

 of minute teeth on this caudal declivity, with long, spine - 

 like seta3, directed anteiiorly ; abd. 6, 7 and 8 have in 

 addition a crescent-shaped plate near the anterior margin, 

 armed with strong spines directed posteriorly ; these reach 

 their greatest development on the 7tli segment. On the
