328 THE CANADIAN ENTOMOLOGIST 



 1911. From egg clusters of Delphax saccharivora in cane leaves. 

 Collected Dec. 19, 1911. Rio Piedras, Porto Rico. Thos. H. 

 Jones." Both the locality and the host are new. Also a female, 

 with the following new variety: 



■5. Aphelinoidea semifuscipennis Girault, variety allipes nova. 



Female. — Like semifuscipennis, but the antenna? and legs are 

 pallid and the colour more yellowish; also the fore wings differ in 

 details hard to describe, but the marginal cilia are finer and shorter 

 and the discal cilia appear denser. 



Two slides from Van Dine through Dr. Howard bearing three 

 females and one male, five females respectively, labelled "126 — 

 1912. From egg clusters of a leaf-hopper. Rio Piedras, Porto 

 Rico. Collected Feb. 1, 1912. Thos. H. Jones." The male did 

 not differ from the female. Types (of allipes) in the U. S. National 

 Museum, Washington, D. C, U. S. A. (Three females on the 

 second slide; the one male and two remaining females practically 

 destroyed.) 



6. Ufens niger (Ashmead). 



Two females from Van Dine mounted on a slide with the 

 Oligosita following, labelled "335 — 1912. From leaf-hopper eggs 

 in cane, collected April 20, 1912. Rio Piedras, Porto Rico. Thos. 

 H. Jones." The species, heretofore, has been known only from 

 the United States. It is associated with commercial crop plants. 



7. Oligosita comosipennis Girault. 



One female with the Ufens just noted. The species is con- 

 nected with commercial crops, and thus is probably widely dis- 

 tributed. The locality is totally new. 



8. Brachistella prima (Perkins). 



Two females on the slide with the preceding two species. 

 This insect was recently described from Mexico, where it was 

 reared from jassid eggs in sugar cane. The spot from the stigmal 

 vein in these specimens crosses to the caudal wing margin; the 

 "irregularly smoky" of the basal part of the wing in the original 

 description forms in these West Indian specimens a first or proximal 

 band across the fore wing at the bend of the submarginal vein. 

 The species is thus characterized by the two-banded fore wings. 

 The specimens agree with the original description otherwise,
