6. Mesopleuron black with central section yellow or testaceous and usually 



elongate nawaii (Ashmead) 



Mesopleuron yellow taitensis (Cheesman) 



Brachycytrus (sic) aporiae Okamoto (1921, pp. 64-65, pi. 5, jQg. 15), 

 as Cushman previously noted, does not belong here. It belongs in 

 the Hemitelini. 



Brachycyrtus pretiosus Cushman 



Brachycyrtus pretiosus Cushman, 1936, Proc. U. S. Nat. Mus., vol. 84, pp. 18, 19, 

 fig. 1, 1936. 



Cushman's excellent description errs in one respect. He stated 

 that the occipital carina extended straight to the base of the mandible. 

 This character, for various reasons, is either very difficult to see or 

 not visible on the Cushman specimens. Fortunately, specimens since 

 added to the U. S. National Museum collection definitely show that 

 the occipital carina meets the hj-postom.al carina before the base of 

 the mandible and does not, as Cushman thought, extend to the base. 

 This species shows very little color variation. It and crossi differ 

 from other species in the genus by the short epomiae, which reach only 

 alittle more than half the distance to thedorsalmarginof thepronotum. 



B. pretiosus ishnown only from Florida. The four additional speci- 

 mens, reared from "trashbug pupae" (chrysopid pupae), are from 

 Sloan's Grove, Tampa, and Haines City, Florida. 



Brachycyrtus crossi (Blanchard) 



Brachycyrtomorpha crossi Blanchard, ("in lit."), Kreibohm de la Vega, Rev. Ind.

 Brachycyrtomorpha crossi Blanchard, An. Soc. Cient. Argentina, vol. 134, pp. 



105-107, fig. 6, 1942. 

 (Brachycyrtus) crossi Kreibohm de la Vega; Townes, Mem. Amer. Ent. Soc, No. 



2, pt. 2, p. 756, 1945. 



Kreibohm de la Vega had no intention of validating the name crossi, 

 which he attributed to Blanchard, but he certainly would have done so 

 had the figure (a photograph) not been too poor to distinguish it from 

 other brachyc3'rtine species known at the time. 



B. crossi, most closely related to B. pretiosus Cuslmian, is immedi- 

 ately distinguished from it and all other kno-wnspeciesoi Brachycyrtus 

 by the whitish thorax with three broad, reddish bro^\^l stripes. 

 Blanchard speaks of the thorax as bemg whitish yellow, and the 

 scuteUum pale ivory. In the specimens before me the scutellum and 

 thorax are the same color, though the spaces between the ferrugineous 

 stripes of the scutum are slightly tawny or yellowish. Other-udse the 

 two males agree very well with Blanchard 's description. The female 

 differs from the male in having the spots of the pleural areas paler and
