Dorsum of epinotum convex, short, not distinctly delimited from the 

 vertical declivity. First segment of petiole as long as wide, the sides 

 feebly convex and parallel. Second segment transversely ovate, 

 hardly wider than the 1st. Wings hyaline, nervures pale brown.

 collection.) 



As I have remarked on a previous page, cacodaemon, Forel, includes 

 two quite distinct forms, those from Willowmore being no more than 

 a slight variety of castanea, race rufonigra.

£ . 4" 1-5 mm. Yery dark reddish-brown. Sculpture stronger 

 than in the type of the species of var. angustior. Thorax longitudinally 

 rugose (in one specimen belonging to the same nest the thorax is 

 very distinctly transversely rugose). Median tubercle of mesonotum 

 larger and more prominent than in the type of the species. The 

 sides of the head are less convex, and the 2nd node of the petiole is 

 more deeply grooved in the middle. Otherwise like the type-species.

£ . 4"5-5 - 2 mm. Light reddish-brown, the back of the head and 

 the apical half of the abdomen darker than the rest, mandibles 

 yellowish-red. Pro-mesonotal suture less deeply impressed than in 

 the type- species, sculpture of the thorax a shade stronger, particularly 

 on the epinotum. In all my specimens the mesonotal carinula is as 

 strong as, or even stronger than in the type-species, and the petiole, 

 contrary to Forel's description, is not wider than in the type-species. 



" $ . More robust than the type. The mesonotum entirely smooth 

 (partly striate in the type of Peringueyi)."
