Female. — ^In structural characters, sculpture, and pubescence agree- 

 ing throughout with terminalis (Say), except that the head averages 

 still wider as compared with the length and the antennal scape is 

 slightly wider. Length, 1.28 to 2.26 mm. 



Coloration as in jiaminius (Dalman) and imdergoing the same 

 variations, except that the tibial spur and middle tarsi are always 

 yellowish white, the hind tarsi always brown or blackish, and the 

 luster apparently never bluish on the head and notum. 



Male. — Like the female, except that the markings on the wings are 

 paler and the size averages smaller. Length, 1.38 to 2.15 mm. 



The following material has been examined: 



Series 1. Sixteen females, tv. o males (includmg four female cotypes) 

 reared from a larva and pupa of Cheilomenes sexmaculata (Fabricius) 

 (an oriental Coccinellid which was liberated in considerable numbers 

 during 1912 in California), IViiittier, California, Jidy 12, 1912 (P. H. 

 Timberlake). Head deep slate olive (R.) with a metallic luster, the 

 oral margin brovrnish yellow; pronotum and mesonotum black with 

 a greenish luster, underparts of thortix antique brown (R.), suffused 

 with raw umber (R.) and with a bluish or purplish luster, especially on 

 the posterior half of the mesopleura; antennae black, the scape slightly 

 bluish metallic, the club and more or less of the sixth funicle joint in 

 most of the specimens yellowish white ; front and hind legs and middle 

 coxae mostly bro-wnish black with a bluish or purplish luster, espe- 

 cially on the coxae, the front femora considerably brov/ner; middle 

 femora about raw sienna (R.) and with a pale yello\nsh annulus near 

 the base; middle tibiae dark brown, the spur and the middle tarsi 

 except the last two joints yellowish white. Funicle unusually short, 

 the joints subequal, the first joint in most of the specimens no longer 

 than thick; the postmarginal vein about a fourth shorter than the 

 stigmal. Length of female, 1.28 to 1.57; length of male, 1.38 mm. 



Series 2. Six females, two males reared from larvae of Adalia 

 hipunctata (Linn sens), Salt Lake City, Utah, August 17 to September 

 13, 1913 (P. H. Timberlake). Similar to the precedhig series, but the 

 head somewhat brighter green, the luiderparts of thorax purer 

 antique brown (R.), being darker and metallic only on the posterior 

 margin of the mesopleura; the last fimicle joint slightly more brown- 

 ish than the other jomts, but not whitish; middle femora more
