2. Prostethophyma minor, sp. n. (Fig. 1, B.) 



S . Smaller and more slender than P. cephalica, Bol. 

 Aiitennte extending well beyond the hind margin of the 

 pronotum. Head very strongly reclinate ; frontal ridge 

 ])arallel thronghout, scarcely narrowed at the fastiginm, 

 where it is strongly convex and sparsely punctured, while 

 the rest is fiat, with a very shallow impression below the 

 middle ocellus and covered with strong, though not dense, 

 impressed points ; face strongly punctured, but less so than 

 in P. cephalica ; facial keels reaching the clypeus. Fas- 

 tigium of the vertex as in P. cephalica ; temporal foveolse 

 scarcely perceptible^ indicated by puncturation. Median 

 keel of the pronotum low and rather thick, interrupted in 

 its middle by the typical sulcus ; lateral keels feeble, 

 distinctly (and more than in P. cephalica^ convergent 

 towards the first sulcus, strongly divergent behind, not 

 reaching the hind margin, both front and hind part of 

 each keel being straight ; hind angle of the pronotum 

 obtuse. Venation of the elytra much like that in P. cepha- 

 lica^ but differing in the following points : externo-median 

 area more dilated, twice as broad as the scapular area and 

 subequal in its width to the inter ulnar area, which is less 

 dilated than in P. cephalica ; discoidal area a little wider 

 than in P. cephalica, and regularly transversely venulated 

 except the very base. 



Coloration as in P. cephalica, but paler. Lateral lobes of 

 the pronotum with only an elongate pale callous spot below 

 the middle, instead of a more narrow longitudinal callous 

 line extending across the lobes as in P. cephalica. Elytra 

 hyaline, spotless, with the apex strongly infumate and with 

 a pale callous streak in the basal half of the scapular area. 

 Wings as in P. cephalica. Hind femora on the outside 

 greyish yellow, with brownish points along the upper 

 Ciirina ; the upperside with very indistinct transverse 

 fasciae ; the inside orange-red, with a blackish fascia before 

 the apex and a blackish spot at the middle of the upper 

 margin ; the lower sulcus of the femora yellowish ; the hind 

 knees black. Hind tibiae with black coudylus, pale basal 

 third, bright red in the rest. 



? (paratype). Differs from that of P. cephalica by the 

 smaller size and some characters in the venation of the 

 elytra : the hind radial vein is more bent backwards and the 

 externo-median area is therefore broader and with regular 

 transverse reticulation ; the discoidal area is regularly trans-
