shallow longitudinal furrow over the depression ; the 

 clypeus obliquely depressed in the middle at the centre, 

 the depression almost semicircular ; the top with a few 

 punctures ; the centre below the antennae broadly, roundly 

 and distinctly raised ; the mandibles rufo-testaceous ; the 

 tips black ; the palpi pale-testaceous. The frontal 

 depression black ; the vertex blackish at the ocelli ; the 

 inner orbits narrowly at the bottom, broadly at the top, and 

 narrowly again behind the eyes, yellow. Prothorax in front, 

 the edge of the pronotum, two lines in the centre of the 

 mesonotum, the scutellum except at the apex, the pro- 

 pleurae and the mesopleurae over the coxae, lemon-yellow ; 

 the propleurae almost entirely black, as is also the sternum ; 

 the upper half of the mesopleurae, and the metapleurae, 

 black ; the mesopleurae strongly punctured, except the usual 

 smooth space behind; the base above almost longitudinally 

 striated ; the metapleurae very finely and closely longitu- 

 dinally striated ; a red and yellow mark over the coxse. 

 Scutellum flat, large, not much narrowed towards the apex, 

 the post-scutellum rufous, very smooth, and having two 

 large, deep, oval depressions at the base. Median segment 

 shagreened, almost striated in the middle ; the supra- 

 median area longer than broad ; bluntly rounded at the 

 base. The four anterior coxae coloured like the femora ; 

 the hinder broadly black at the base beneath, and with 

 a yellow mark at the base behind. Abdomen shining, 

 the apex of the fourth, the fifth and the sixth, black. In 

 the fore wings the transverse median nervure is interstitial; 

 the areolet is much narrowed at the top, being there less 

 in length than the space bounded by the recurrent and 

 the second transverse cubital ncrvures. 



Appears to be a true Dicoelotiis, the first species of the 

 genus recorded, I believe, out of Europe, The foveae at 

 the base of the post-scutellum are large and deep, more so, 

 in fact, than in most species of the genus.
