 frrruginous beneath, &c. From M. confusa (with whicb 

 someone had identified one of the specimens) it dilfers by 

 the ct)ns|)ienons tnfts of liji;ht hair at extreme sides of fittli 

 ab(h)minal segment ; the broader face ; the light hair of 

 hi!)rnm ; the eolonr of the antennie ; the coh)nr of liair of 

 nii(hlle tarsi ; the light hair on tegnhe, S:c. From M. yr'tn- 

 de'iie it differs by the sides of the mesothorax being broadly 

 covered with pale ochreons hair, the black hair not closely 

 approaching tegnhe ; the light hair on tcguhe ; the abdominal 

 bands narrower and not so yellow ; the apical plate broader ; 

 the eolonr of hair on middle tarsi, &c.

Melissodes ay ills, Cress an, var. stt/jafji/is, Ckll. 



Four males from Fedor, Texas {Rirkinann), represent a 

 variety between ai/Uis proper and siibayills. The size is 

 small and the mandibles have no yellow spot ; the labrum 

 is sometimes entirely black, sometimes with a yellow spot. 

 The pubescence, while very pale, is yellowish, not pure white 

 like that of M . Snoiri. Tlic rather narrow face agrees witli 

 subayi/is, and they should rank with that form rather than 

 with true uyilis.

"What I think nui^t be the (J of this is from Fedor, Texas, 

 May '61, I'JOl {Birkmann). It runs in my tables to M.per- 

 plexa, but has a large light spot on labrum, upper part of 

 elypeus without black, and less black hair on mesothorax. 

 1 presume that it \\dl be impossiljle to certainly match the 

 texes of the closely allied species of this group without field- 

 observations. 



Xenoglossa brevicornis (Cress.). 



Mr. Birkmann has taken both sexes at Fedor, in June. 

 The female, which 1 had not before seen, runs in my tables 

 of Melissodes &c. nearest to M. sjjissa, and is indeed extra- 

 ordinarily like that insect, difl'ering from it as follows : — Face 

 i;roa(ler; anterior margin of elypeus not red, but wiili a 

 pair of obscure yellow spots; eyes more convex and pro- 

 minent; marginal cell obliquely truncate (pointed in sjussa}; 

 claws with a divergeut basal tooth of cousiilerablc size on all
