1)iit the description of the pronotum does not correspond, 

 the two deep transverse furrows and tlie longitudinal sulcus 

 mentioned by him being absent in tlie present species. The 

 spines on the clieek are very similar in the two species. 

 P. rosmarus has been transferred by Stadelmann to his 

 genus Dicrof/enmm, which is phaced by Ashmead in his family 

 CosilidiB. I have not seen specimens of the genus, which is 

 said to be without the lobe of the hind wing characteristic of 

 the Bethylidse. But I am inclined to look on the genus as 

 an aberrant Bethylid, rather than transfer it to the position 

 assigned to it by Ashmead. 



Nomineia armaticeps , sp. n. 



(S . Niger, rugose punctatus ; tegulis fuscis ; alls hyaliais, leviter 



infuraatis ; geiiis spina acuta armatis. 

 Long. 8 mm. 



(J . Mandibles tridentate, the inner tooth not well defined, 

 very short and blunt ; second joint of theflagellum no longer 

 than the third, the apical joints not much narrowed. Head 

 much broader than long, front rugose, vertex coarsely punc- 

 tured ; eyes separated from the posterior margin of the head 

 by a distance scarcely equal to their own length ; cheeks 

 armed beneath with a strong spine. Thorax coarsely punc- 

 tured, raesopleurse rugose ; pronotum much narrowed in 

 front, the anterior margin straight. Median segment broader 

 than long, longitudinally striated at the base, the triangular 

 dorsal area well marked, the sides of the area finely obliquely 

 striated, the sides of the segment and surface of the apical 

 truncation rugulose. Abdomen smooth and shining, with 

 sparse white pubescence on the sides and ventral surface, the 

 apical segment punctured. Tarsal ungues bideutate. Sub- 

 median cell incompletely closed, the nervures at the apex 

 indistinct ; recurrent nervure and first transverse cubital 

 nervure indistinctly indicated, not interstitial. An indistinct 

 nervure from the apex of the radius reaching nearly to the 

 margin of the wing.

This is very nearly related to N. spiniyera in the structure 

 of the head and pronotum, but the mandibles are shorter. 

 In both the transverse depression at the posterior margin of 

 the pronotum is absent. In the present species the neura- 

 tion is less developed than in N. spinigera, the submedian 

 cell being imperfectly closed, the recurrent and transverse 

 cubital nervures only indicated, and not interstitial as in 

 A^. spinigera.
