202 PROCEEDINGS OF THE XATIOXAL IIUSEUM, vol. 45. 



caudal wings are broad, nearly twice broader than in JiaviopaUiata. 

 Excepting for the uniform blackness of the body, otherwise as in 

 JIavopaUiata. The male is similar to the female. 



Nothing was known concerning the hosts of this species, but I 

 add a record beyond. I have studied the following specimens: 

 The tj-pes from the United States National Museum collection 

 remounted in balsam from tags labeled "Signiphora nigra Ashm., 

 female, type No. 4767, U.S.N.M., Washington, D. C." The single 

 type slide bears in reahty three males and two females which com- 

 prise the types formerly by im.plication all females. A sUde bearing 

 a single male specimen remounted from a tag in the same collection 

 labeled ''Los Angeles, Calif. Coccus hesperidum L. 160°. Aug." 

 And a tiiii'd shde bearing two males remounted from tags in the 

 same collection, labeled ''Washington, D. C." 



Habitat. — United States — Washington, District of Columbia; Cali- 

 fornia OLos Angeles). 



Host. — Coccus Tiesperidum Linnagus. 



Types. — The three males, two females as indicated in foregoing. 



Homotypes. — Accession No. 45087, Ilhnois State Laboratory of 

 Natural History, Urbana, the two males from U.S.N.M. collection as 

 noted above (Washington, District of Columbia). 



3. SIGNIPHORA AUSTRALIENSIS Ashmead. 



Signiphora australiensis Ashmead, 1900, pp. 409, 410. 

 The original description of this species is exactl}^ as follows: 



Female. — Length, 0.60 mm. Aeneous black, the mesonotum -ndth a bronzy tinge, 

 the scutellum with a slight bluish tinge; legs black, a spot on knees and tarsi white 

 or yellowish-white, the anterior tibise yellowish beneath; wings fuscous with a hyaline 

 band across the disk from apex of the marginal vein. 



Type.— C&t. No. 4771, U.S.N.M. 



Habitat. — Australia. (Albert Koebele, collector.) 



Host. — Rhynch.: Sp. not identified. 



By studying the tA'pes I am enabled to offer the following additional 

 descriptive details: Like nigra but differing colorationally in that 

 the head and thorax are metallic to some extent, the vertex and 

 mesonotum distinctly metallic green (but not in balsam mounts), 

 the latter fineh' transversely lined ; body finely poh^gonally sculptured, 

 including the abdomen (the sculpturing not distinct in balsam 

 mounts); the fore wings differ as described — the}^ are embrowned 

 throughout, but somewhat distad of the middle there is a broad 

 clear band, subcrescentic in shape and touching the costal margin 

 at the apex of the stigmal vein. This area is broader at the caudal 

 margin than at the cephalic one, barely reaching the latter; the 

 stigmal vein differs in that it is like a short conical prolongation 

 bending off slightly from the marginal; thus it is short and much 

 broader at its point of origin than is the case with that of nigra.
