tnead are generically identical, and should they finally be removed 

 from Hexasmicra, it would be proper to retain Ashmead's manuscript 

 name Xanthosniicra with his trinidadensis as the type species. Both 

 species differ from Hexasmicra transversa Walker in having the 

 petiole long (pp. 454-455), the posterior femora abruptly widened 

 from base, and the distance between a posterior ocellus and the eye 

 scarcely as wide as the width of the ocellus. In brasiliensis the dis- 

 tance is distinctly less. In H. transversa Walker the petiole is not 

 longer than wide (pp. 252 and 454) ; the posterior femora are grad- 

 ually (not abruptly) widened from base; and the distance between a 

 posterior ocellus and the eye is distinctly greater than the width of 

 the ocellus. In H. trinidadensis the left mandible is bidentate (the 

 right one is concealed). In H. brasiliensis the dentition can not be 

 studied without relaxing the specimen. The types of both of these 

 species have the femoral teeth black in their apical half. The two 

 are closely related to the type of Hcptasmicra quadrimacHlafa Ash- 

 mead (p. 453), which, in fact, is generically separated from them 

 only by having a seventh, small femoral tooth between the two large 

 basal teeth. 



Leucospis enderleini Ashmead. 

 Lcncospis enderleini Ashmead (Memoirs Carnegie Museum, Vol. I, 

 p. 405, Plate XXXI, Fig. i). — As /\shmead's description and figure 

 ^o not agree, Mr. J. C. Crawford, of the United States National 

 TVTuseum, asked the writer some years ago to examine the type of 

 •enderleini; the writer did not find any specimen in the Carnegie Mu- 

 iseuin labeled Leucospis enderleini, but one female labeled "Leucospis 

 schlettereri Ashm. type," and, as no species so named was described 

 by Ashmead, the writer examined the one labeled schlettereri and 

 found it to perfectly agree with the description of enderleini. There 

 is not the slightest doubt that the specimen labeled L. schlettereri is 

 the type of L. enderleini, and the length of the ovipositor is as de- 

 scribed by Ashmead. but the figure is incorrect. Dr. Schletterer 

 wrote extensively on Leucospis, and Ashmead was evidently thinking 

 of Schletterer and wrote that name on the label instead of enderleini. 

 This happened at a time when the great hymenopterist felt the effect 

 of failing health. The writer has attached a corrected note to the 

 specimen below Ashmead's label for the guidance for future students.
