 pale. Wings hyaline, stigma and veins brown. The female has 13- 

 joiuted antenna', the two basal joints yellowish-brown beneath, the joints 

 of flagellum nearly thrice as long as thick, the terminal joint very large 

 fusiform, twice as long as the preceding joint. The male has 15-jointed 

 antennae, dark brown, the joints of the flagellum are only about twice 

 as long as thick, the terminal joint not longer than the preceding, fusi- 

 form ; the legs are darker than in the female, the middle tibije and tarsi 

 dusky; abdomen ovate, black, the petiole yellowish ; the 2d branch of

Habitat. — Los Angeles, California. 



Described from five specimens, received from Mr. Coquillett, labeled 

 No. 99, reared from Myzus species on Hosaclda glabra. This species is 

 very close to L. cragrostaphidis and may be a variety. 



Lysiphlebus citraphis Ashm. 



f Aphidiua citraphis Ashm., Orange Ins., 1880, p. 71. 



Trioxys testaceipes Cress, (pars), U. S. Agri. Rep., 1879, p. 208. 



Aphidaria basilaris Prov., Add. a, la Faune Hym., p. 306, 1888. 



This species is parasitic on the orange Aphis, Siphonophora citrifolii 

 Ashm. ; it is identical with some of the forms described by Mr. Cresson 

 (loc. tit.), but as that author confused three species, which bear a super- 

 ficial resemblance to each other, reared from the cotton Aphis, orange 

 Aphis, and wheat Aphis, I have retaiued the name given by me to the 

 species reared from the orange Aphis, his name for the species reared 

 from the cotton Aphis, and given the name L. tritici to the species 

 reared from the wheat Aphis, which, under the circumstances, is, I be- 

 lieve, admissible. See the table for the characters that separate them.
