204 HELOTA GUINEENSIS. 



bisinuate, each sinuation divided into two smaller ones, 

 median lobe subtruocate, the lateral angles acute. Upper 

 surface remotely and irregularly punctured. Scutellum trans- 

 verse, glossy and impunctate. 



Elytra parallel, narrowly flattened along the sides, each 

 of them provided with ten regular striae of rather small 

 punctures which become slightly larger towards the sides 

 but finer towards the end of the elytra ; the interstices 

 are impunctate ; the 1 st (sutural), 3 rd , 7 th and 9 th inter- 

 stices are distinctly raised on the apical portion, the 3 rd 

 and 9 th extend to the apical margin. 



Under surface : the triangular middle portion of the head 

 is sparingly covered with fine but distinct punctures, the 

 lateral portions are more strongly punctured ; the sterna 

 show some large punctures laterally and the elytral epi- 

 pleurae some fine punctures along the inner margin of the 

 basal fourth; the abdomen is nearly impunctate, the legs 

 are impunctate. 



cf. Legs more slender and more elongate than in the 

 9; the underside of the anterior femora shallowly furrowed, 

 covered on both sides of the smooth furrow with very 

 minute warts ; anterior tibiae flattened beneath, slightly 

 curved in their apical half, the inner margin, of the cur- 

 vation fringed with fulvous hairs; intermediate tibiae with 

 a minute triangular tooth at the end of the underside; 

 posterior tibiae densely fringed on the underside of the 

 apical third with fulvous hairs which increase in length 

 towards the tip. — Ventral segments with a small group 

 of hair-bearing punctures on both sides of the middle, the 

 basal segment shallowly impressed along the middle, the 

 impression provided with a small tuft of fulvous hairs, the 

 apical segment broadly subtruncate posteriorly and with a 

 large semi-ovate smooth impression in front of the trun- 

 cation. — Elytra nearly conjointly rounded at the apex, 

 slightly dehiscent at the suture, the posterior margin faintly 

 sinuated, the 7 th interstice sharply raised from one third 

 from the base.
