ABT, 2. CHALCID-FLY GENUS CHRYSOPLATYCERUS TIMBERLAKE. 5 



Head and thorax ferruginous, the abdomen bluish black with an aeneous luster ; 

 antennae brownish black without a metallic luster on the scape; legs brown 



with the tibiae fuscous and the tarsi mostly whitish howardii Ashmead. 



4. Frontovertex a little wider than long, llnely rugosely wrinkled and with 

 scattered shallow pin-punctures ; mesoscutum and scutellura strongly con- 

 vex, the axillae somewhat elevated with a declivous posterior face ; general 

 coloration black, somewhat shiny but hardly metallic; face, axillae, and 

 metapleura more or less distinctly metallic green, the mesopleura and 

 abdomen more bluish ; antennae and legs black with a slight bluish luster 

 on the hind femora, the spur of middle tibiae and the tarsi except apical 



joint brownish yellow ferrisi, new species, 



Frontovertex no wider than long, more finely wrinkletl and with fewer, 

 shallower pin-punctures; mesoscutum and scutellum slightly depressed 

 medially, especially in the longitudinal axis, the axillae not at all promi- 

 nent or scarcely elevated above the scutellura ; general coloration black 

 with a slight bluish and aeneous luster, the face, cheeks, pleura, sides of 

 the scutellum and the abdomen with a strong bluish luster ; antennae opoque 

 black ; legs usually dull blackish, but the femora in one specimen with 



a distinct bluish luster, the apex of middle tibiae, the spur, and the middle 

 and hind tarsi except apical joint pale yellowish, the trochanters and front 



tarsi dusky yellowish splendens (Howard). 



1. CHRYSOPLATYCERUS SPLENDENS (Howard). 



Rileija splendens Howaed, Entom. Amer., vol. 4, p. 80, July, ISSS ; and Canad. 

 Eutom., vol. 20, p. 194, Oct., 1888. 



My specimens of this species were reared as follows : Two females 

 from Pseudococcus ryani (Coqiiillett) on cypress, Pasadena, Califor- 

 nia, August 13, 1911, and August 19, 1912 (P. H. Timberlake) ; two 

 females from a species of Pseudococcus on Geratonia siliqua^ Coro- 

 nado, California, September 27 and October 8, 1912 (P. H. Timber- 

 lake) ; one male from Pseudococcus cU7^ (Risso) bred experimentally 

 November 24, 1912, from a female captured at Whittier, California 

 (P. PI. Timberlake) ; one female, one male from Pseudococcus mari- 

 thiius (Ehrhorn), Riverside, California, October, 1914 (C. P. Clau- 

 sen) ; and one male from a species of Pseudococcus on Geratonia 

 siliqiia, Pasadena, California, July 29, 1915 (E. J. Branigan). 



The original host was an undetermined mealy-bug on passion- 

 flower vines at Los Angeles, California (Albert Koebele) , and Essig ^ 

 records this parasite from Pseudococcus citri at Santa Paula, Cali- 

 fornia. According to my own observations on the parasites of citri in 

 California, splendens is infrequently met with and is imperfectly 

 adapted to this host. In the experiment mentioned above the female 

 was supplied with a large colony of citri on potatoes and although 

 she was observed to oviposit frequently only a single male was reared. 



The original figures given by Howard^ and those by Essig- are 

 characteristic of this interesting parasite and show many of the struc- 

 tural pecularities of the genus.
