NOMADA PLANISCUTA, n. sp. 



Rufo-testacea, capite thoraceque nigris, rufo ornatis, scutello 

 planiusculo, mesopleuris nitidis, valde punctatis, alarum, cellula 

 cubitali tertia angusta, superne constricta, tibiis posticis, spinis

^ . Rufo-testaceous, a triangular spot on the vertex of the head its 

 apex reaching to the insertion of the antennse, the thorax and 

 propodeum, with the exception of a spot on each side of the pro- 

 notum, the tubercles, teguhe, scutellum, and post-scutellum as well 

 as a spot on each of the mesopleura; bordering the prothorax, black. 

 The coxce of the front and hind pairs of legs are also almost entirely 

 black ; wings smoky-brown, apices of the 2nd and 3rd abdominal 

 segments more or less infuscate. Head short, strongly punctured, 

 cheeks not developed, labrum sparingly clothed with pale hairs, 

 punctured, bearing a very small laterally compressed tubercle near 

 its apex, antennce with the 2nd and 3rd joints subequal, 4th 

 slightly shorter, the rest nearly quadrate, vertex and cheeks behind 

 the eyes clothed with short black hairs, mesonotum closely and 

 strongly punctured, with signs of having had a clothing of short 

 black hairs (both my specimens judging from the condition of the 

 wings are possibly more or less rubbed), scutellum not raised, 

 shining, rather more largely and less closely punctured than the rest 

 of the mesonotum, its centre impressed posteriorly, mesopleura3 

 shining very largely and distinctly punctured, wings with the 3rd 

 submarginal narrow, much contracted above (in one specimen this 

 cell in the right hand wing is divided in two by a transverse nervure 

 situated towards its apex), propodeum punctured at the sides, its 

 area very finely rugulose, its extreme base slightly rougher, hind 

 tibiae with two curved short spines, close together, as in sxtccincta, 

 mephisto, fucata, manni, etc.; abdomen closely punctured, with only 

 the extreme posterior edges of the segments shining, apex of the 5th 

 segment clothed with whitish hairs.
