 tlii-ir inner border-; nearly paral'el, leaving an equal front; the base of the 

 antenna' c;in not 1)0 made out, but beyond the long basal joint are six nearly 

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

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

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

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

 the ovipositor extends very slightly, apparently by pressure. 



( >u another stone, collected bv Mr. Richardson, is pretty certainly 

 aiiotln ! specimen of this species, in which the abdomen is distorted by piv-- 

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

 re>:ilt is an apparently slenderer abdomen : it is also a female, with exactly 

 the SIMP- 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.

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

 be di.Minct from any described liviuir forms. It is related to Calvptus. Imt 

 ilillers from it in tlie neuratiou of the front wings, mainly in the short: 

 ot the tirM >nlimedian cell, the division between which and the second >ub- 

 mediaii cell lies much beion- the lower extremity of the first m.-drm cell: 



and still more in the shape and position ot' the lir>l Mihcostal and second 

 median cell>: the vein which separates them is in Mrai^hf continnitv \\'iih
