hind tibiae black except for a white aiinulus covering about the 

 penultimate fifth ; hind tarsi black. 



Wing somewhat brownish, first posterior cell not wider than the 

 submarginal; tip of second vein farther from base than anterior 

 end of hind crossvein. 



Length, about 7.5 mm. (the abdomen having been detached and 

 glued on the mount, the length can not be positively given). 



jRedescribed from one male, Santos, Brazil, received from Doctor 

 Krober, under the name of ethiopa Townsend. 



This might be a male of speciosa, except for the marked difference 

 in the length of the third antennal joint, which does not seem to vary 

 in the two sexes in any of the other species. 



STYLOGASTER DECORATA, new species 



Male. — Precisely like 07'natipes in most of the characters, the 

 only differences that I can make out being as follows: The third 

 antennal joint is not only broad near base, somewhat bulging below, 

 but continues rather wide to the apex; the second joint is a little 

 shorter than in ornatipes so that the third is about three times its 

 length; the dark pleural stripe extends upon the sternopleura, but 

 not upon the pteropleura. The front coxae have ordinary short 

 bristles at tip, the middle femur is less thickened, the middle tibia, 

 although enlarged from the middle, is not so broad as in ornatipes,' 

 it has a cluster of black hairs on the flexor side beginning slightly 

 before the middle and confined to a narrow space along that side; 

 although striking, it is much less so than the corresponding tuft in 

 ornatipes. The front side of the tibia also has a few unusually long 

 hairs on the apical half, but they do not form a conspicuous tuft. 

 The middle basitarsus is not enlarged, but has, beginning almost at 

 the middle, a series of five small suberect setules. The bristles of 

 the first and second abdominal segments are the same. 



Wing: The first posterior cell distinctly narrower than submar- 

 ginal. 



Length, 6 mm. 



Described from two males; the type from Higuito, San Mateo, 

 Costa Rica; the other from La Suiza de Turrialba, Costa Rica, both 

 collected by Pablo Schild, and the second received from Prof. A. 

 L. Melander, to whom is is returned. 



Type.—Mfx\Q, Cat. No 43025, U.S.N.M. 



STYLOGASTER CURRANI, new species 



Male. — Frontal triangle very short, the shining portion ex- 

 tending in front of the median ocellus hardly more than the diameter 

 of the latter. Entire front reddish brown, very little paler close 

 to lunule, bordered on each side by a narrow, darker brown orbital 

 stripe. Antennae brown, first joint and extreme base of second 

 white, third joint slightly reddish below and around the tip, about
