pallide testaceis ; nervus prsebrachialis distinetus. Mesothoracis 

 sulculi baud penitus obliterati. Metathorax brevis, postice trun- 

 catus, ibidem excavatus, medio oarihulatus. Segmentum lum 

 totius abdominis triente longius, a basi hide ad apicem perpaulo 

 ampliatum, tuberculis inconspicuis. Terebra abdominis quintam 

 partem adsequans. 



£ aliter coloratus ; niger, prothorace, antennarum scapo, ventris 

 basi, testaceis ; mesothoracis disco, scutello, abdominis segmento 

 2o, saturate rufo-piceis ; coxis posticis infuscatis. 



5 . Rufo-piceous or piceo-testaceous ; eyes, a blotch on the 

 face and on the occiput, stemmaticum, scutellum, metathorax, and 

 1st abdomidal segment, black or blackish ; segments 2 — 3 dark 

 rufo-piceous, the rest pale rufous. Antennas fuscous, joints 1 — 5, 

 together with the legs, pale testaceous. Wings hyaline, nervures 

 and stigma pale testaceous ; prsebrachial nervure distinct. Meso- 

 thoracic sutures not wholly effaced. Metathorax short, truncated 

 and excavated behind, carinated in the middle. First segment 

 longer than £ of the abdomen, very slightly widened from the base 

 to the apex ; tubercles inconspicuous. Terebra as long as I of the 

 abdomen. 



The S~ is black, with the prothorax, scape of the antennae, and 

 belly at the base, testaceous ; disk of the mesothorax, scutellum, 

 and 2d abdominal segment dark rufo-piceous ; hind coxae infus- 

 cated. Length, 1^ ; wings, 3 lin. 



Var. 2 • Head pale rufo-testaceous, only the eyes and stem- 

 maticum black. 



Antennas $ as long as the body, 26-jointed ; of the ? shorter, 

 22 — 23-jointed. Entirely smooth and shining. Mesothoracio 

 sutures indicated by two shallow grooves in front, which are 

 evanescent before reaching the scutellum. The medial carina of 

 the metathorax bifurcates at the declivity, its two branches 

 surrounding the posterior concavity and forming 3 areas, whereof 

 the 2 lateral are smoother and more shining than the posterior. 

 Terebra testaceous, with black valves. The variety, owing to its 

 rufous head, resembles a Dinocamptus. 



Described from three males, three females, taken in a 

 wood near Barnstaple, a male from St. Albans, and 

 another in Fitch's collection. Capron has taken five 

 females and one male at Shiere.
