90 HYMENOPTERA. 



transverse medial nervure obsolete; this I was partly led to 

 do by a remark in Shuckard's Essay : " the Rev. C. Bird 

 showed me a remarkable variety (of P. crassicornis) which 

 has upon the left side the nervures o^ Aporm.'' Having 

 fortunately obtained a fine seiies of Evogethes at Bourne- 

 mouth, including both sexes, I shall here characterize both 

 genus and species afresh. 



Genus Evagethes, St. Farg. 

 Head.— Subrotund, slightly wider than the thorax ; eyes 

 lateral, large and ovate ; the ocelli in a triangle on the vertex ; 

 the mandibles bidentate; the antennee inserted in the anterior 

 part of the face, incrassate in the middle, and tapering to a 

 point at their apex. Thorax somewhat gibbous ; the pro- 

 thorax transverse ; the metathorax short and obtuse ; the 

 superior wrings with one marginal and two submarginal cells ; 

 the marginal cell small, subtriangular, not extending beyond 

 the second submarginal; the first submarginal cell oblong, 

 the second subquadrate and slightly narrow^ed towards the 

 marginal cell, receiving both the recurrent nervures ; the 

 second recurrent nervure received near to, not at, the apex of 

 the cell. The anterior tarsi of the female ciliated outside, 

 and all the tibiae and tarsi spinose. 



Evagethes bicolor. — Female.— Black, with the first, 

 second and extreme base of the third segment of the abdo- 

 men red. Head with a fine silvery pile, most dense on the 

 face ; the anterior margin of the clypeus and the tips of the 

 mandibles rufo-piceous. The thorax at the sides, beneath 

 the metathorax and legs, with a fine silvery pile ; the pos- 

 terior margin of the prothorax arcuate; the w^ngs fusco- 

 hyahne, w^ith a broad blackish border on their apical mar- 

 gins. Abdomen covered with fine silky silvery pile. 



Length 2^-3^. lines.
