HYNENOPTERA— BRACONID.E. 605 



otherwise well rounded, the face tapering below, the eyes large, deep, with 

 their inner borders nearly parar.el, leaving an equal front ; the base of the 

 antennae can not be made out, but beyond the long basal joint are six nearly 

 equal quadrate joints, increasing very slightly indeed in size away from the 

 head, scarcelv so long as broad, the spiral joint subconical, scarcely longer 

 than the peiudtimate. Thorax compact, globose, minutely granulated like 

 the head ; the abdomen also compact, arched, the tip rounded ; beyond it 

 the ovipositor extends very slightly, apparently by pressui'e. 



On another stone, collected by Mr. Richardson, is pretty certainly 

 another specimen of this species, in which the abdomen is distorted by press- 

 ure ; the abdomen shows this by the rupture of the integument, and the 

 result is an apparently slenderer abdomen ; it is also a female, with exactly 

 the same parts preserved, with the addition of the other antenna; but both 

 antenna? are more obscure than in the other specimen, especially at the 

 apex ; they appear, however, to enlarge more rapidly and may be clavate 

 at the tip, in which case the insect can not be the same. 



Length of body, (of No. 4076), 1.85""" ; of abdomen, 0.95""° ; of 

 antennae beyond basal joint, 0.4"™; width of penultimate anteimal joint, 

 0.045™".

This name is proposed for a genus of fossil Braconidae, which seems to 

 be distinct from any described living forms. It is related to Calyptus, but 

 ditfers from it in the neuration of the front wings, mainly in the shortness 

 of the first submedian cell, the division between which and the second sub- 

 median cell lies much before the lower extremitv of the first median cell; 

 and still more in the shape and position of the first subcostal and second 

 median cells; the vein which separates them is in straight continuity with 

 that separating the second subcostal and third median cells, so that the sub- 

 costal cells and the median cells lie in parallel lines along the longer diam-
