covered with thin, short, pale yellowish gray hair, the last four seg- 

 ments showing the metallic reflections more distinctly than the first.

Hob. Boulder, Colorado; one ( type) 5.5 mm. long, at 

 flowers of Claytonia rosea Rybd., April 20 (T. D. A. Cocker- 

 ell) ; one 6 mm. at the flowers of Bursa bursa-pastoris (L.), 

 May 22, 1907 (G. M. Kite) ; one 6.7 mm. long, June 10, 1907 

 (G. M. Hite) ; one 6.5 mm. long at flowers of Taraxacum 

 taraxacum (L.), April 16, 1908 (S. A. Rohwer) ; and Rito de 

 los Frijoles, New Mexico, five 6 to 6.5 mm. long, August 1910 

 (W. W. Robbins). 



This species probably belongs to the group of H. nymphaea- 

 rum Rob. and is most closely related to H. cattellae. The close- 

 ly punctured mesonotum distinguishes it from all the species of 

 the group except H. cattellae, from which it differs in having a 

 longer face, a rim around the basal area of the metathorax, 

 and a closely punctured disc of the second abdominal segment. 

 Individuals of H. perpunctatus with but little of the metallic 

 reflection on the abdomen somewhat resemble H . perdifFicilis 

 Ckll. from which the broad basal area of the metathorax, the 

 sharply lineolate mesonotum and the whitish, not yellowish 

 gray of the pubescence on the abdomen separates it. 



A Twelfth New Genus of Hymenoptera Tricho- 

 grammatidae from Australia. 



By A. A. GIRAULT, Nelson (Cairns), North Queensland, 



Australia. 



LATHROMEROIDES new genus. 



(Hymenoptera Chalcidoidea, Family Trichogrammatidae, Subfamily 

 Chaetostrichinae, Tribe Lathromerini.) 



Female. Similar to Lathromerella Girault, but the anten- 

 nal club only three- jointed and not terminating in a spinelike 

 seta, the discal dilation of the fore wing dense and together 

 with the venation as in Aphelinoidea, the marginal cilia of 

 the fore wing very short ; moreover, the abdomen is very long 

 and tubular, nearly twice the length of the head and thorax
