THE TRIBE CHALCIDINI — ^BURKS 307 



A good series of material from the Southwestern States is needed 

 go that it will be possible to associate the females of this species with 

 these males. 



Host. — ^Unknown. 



SPILOCHALCIS PHAIS, new species 



Figure 9, 6 



This species differs onl}^ slightly from S. mariae (Riley) redescribed 

 on page 304. 



Description. — Female: 5-6.5 mm. Except for the characters men- 

 tioned in key above, identical with female of S. mariae. 



Male: 4-5 mm. Identical with the male of S. mariae^ except in 

 the following characters : Anteromesal margin of antennal scape only 

 slightly sinuate near apex (fig. 9, &), not strongly incised as in S. 

 igneoides (Kirby) (fig. 8, s) or S. mariae (fig. 8, i), scape broadened 

 from base to apex, apex deeply excavated, outer anterior apex 

 rounded, rather than acutely produced, as in S. mariae (fig. 8, ^) ; 

 pedicel cylindrical, two-thirds the length of segment 4, ring segment 

 one-quarter the length of segment 4, segments 5 to 10 equal, somewhat 

 variable, usually longer than wide, last three segments slightly shorter 

 than 10; width of malar space three-tenths the height of compound 

 eye; frontogenal suture slightly curved; combined widths of com- 

 pound eyes equal to or slightly greater than interocular space at level 

 of antennal bases; diameter of posterior ocellus one-half the width 

 of interocellar space; outer surface of metafemur glabrous, ventral 

 margin provided with 12 to 18 minute, closely set teeth; petiole 

 slightly less than twice as long as wide, basal lamina narrow, lateral 

 carinae wanting; gaster slightly longer than metafemur. 



Type locality. — Texas. 



Types. — Holotype, male, Brownsville, Tex,, May 1921, J. C. Brid- 

 well ; paratypes, Brownsville, Tex., May 1921, J. C. Bridwell, 1 male, 

 C. H. T. Townsend, 409, 1 male, Victoria, Tex., 1 male, Maverick 

 County, Tex., December 29, 1915, J. D. Mitchell, 1 male. All types 

 deposited in the U. S. National Museum. 



Host. — The specimen collected by J. D. Mitchell in Maverick 

 County, Tex., was reared from the pupa of a moth probably belong- 

 ing to the family Ceratocampidae, although tliis host pupa is too 

 poorly preserved to be identified accurately. 



The xanthostigma Group 



The xanthostigma group includes the genotype of Spilochalcis. 

 Most of the species of Spilochalcis described from India and Africa are 

 also apparently referable to this group. All the species of this group 

 are rather rare, but most of them are widely distributed.
