shining; all the segments with thin whitish pruinosity above in 

 certain angles, more constant below; fourth segment with some 

 smallish bristles, only scars in the type; genitalia (fig. 1) small, 

 with characteristic broad lobe like outer forceps of the "Dexiidae," 

 the penis long, slender, and jointed. Legs yellow (only the front 

 ones present). 



Wings distinctly infuscated; fourth vein obliquely but rather 

 angularly bent, the first posterior cell rather widely open distinctly 

 before the apex; first vein bare, third with 

 three or four small hairs at base. 

 Length, 8 mm. 



Described from one male, collected in Brazil 

 by Beske, sent for identification by the Vienna 

 Natural History Museum, to which it is 

 returned.

The synonomy is from the type specimens in the National Museum. 

 Both species Avere described from Peru ; Townsend placed Incamyia 

 in the family Phaniidae, and Sphalloglandulus in his Exoristidae. 

 He apparently combined these families with Tachinidae later. 



The genus is allied with Lydella and Eucelatoria in having in- 

 frasquamal setules (a small group of minute hairs on the thorax 

 just below the line of attachment of the hind calypter), except in 

 one species noted below, and in having in the female sex a keeled 

 abdomen with piercer of about the same type. From Lydella it 

 differs in having hairy eyes, and from EucelatoAa also by having 

 the facial ridges much more bristly and the second antennal joint 

 longer. Phorocera is also a related genus, but it has the second 

 antennal joint less than half the third, the face more receding, small 

 apical scutellars, and no median upright pair of discal scutellars. 



The type species of Incamyia and the three new species here 

 described form a very compact group occuring in Peru, Chile, and 

 Argentina, all being black in color with mesonotum bearing a median 

 whitish stripe and a well-defined lateral border of the same, so as to 

 give the effect of a heaA-y black stripe each side of the middle on Avhite 

 ground. The face is nearly vertical, back of head prominent below, 

 cheek equal to nearly one-third of eyeheight. The back of head
