5. Cyphomyia pilosissima. 



Cyphomyia pilosissima, Gerst. Linn. Ent. xi. p. 293 \ 



Ha b. Mexico \ Mexico city (Schumann), Cuernavaca in Morelos (H. H. Smith). 



Three specimens, including both sexes, belonging evidently to this species, though the 

 male shows some discrepancies from Gerstacker's description. The* third joint of 

 the antennae is not " abgestumpft," but is obtusely pointed ; the erect pile of the 

 mesonotum is not blackish, but dusky white ; the tip of the first joint of each tarsus 

 and the whole of the second joint are dark coloured. The differences shown by the 

 female (Gerstacker described the male) are as follows : — 



2 . Front broad, sparsely white-pilose ; in the middle with a sharp carina, which is most prominent a little 

 below the ocelli ; posterior orbits with white pile ; pile of the face less abundant and long in the middle. 

 Mesonotum with three elongate white-tomentose spots in front ; the pile elsewhere much shorter and 

 less abundant than in the male. The pile of the eyes is distinct, but much shorter than in the male. 



C. pilosissima was placed by Osten Sacken (antea, p. 43) amongst the unidentified 

 Mexican Stratiomyidae. 



6. Cyphomyia lasiophthalma, sp. n. (Tab. IV. fig. 15, e .) 



c? . Eyes densely black-pilose. Antennae slender, the first joint unusually long and slender, nearly four times 

 the length of the second, which is about twice as long as wide ; first joint yellow, clothed with black 

 pile ; second joint also yellow, but clothed with black and white pile ; third joint yellowish on the basal 

 portion, black distally ; the last segment of the third joint is nearly three times the length of that 

 preceding it. Pace shining black, at the immediate margin of the eyes more thickly pilose, in the middle 

 with long white pile. Mesonotum rather thickly clothed with yellowish-white tomentum, apparent, when 

 seen obliquely from behind, as three stripes, and with long, erect, moderately abundant, dusky pile ; 

 scutellum clothed with black pile, except on the margin and spines, where it is longer and white ; spines 

 yellow, about as long as the scutellum, slender, gently divaricate, and curved upward at the tip. Pleurae 

 with abundant white pile. Abdomen nearly opaque black, with four distinct triangular spots composed 

 of yellowish-white appressed pile on each side. Legs black, with white pile ; the basal half or two- 

 thirds of each of the femora and the first two joints and proximal part of the third joint of all the tarsi 

 light yellow. Wings yellowish-hyaline, with a broad brownish band across the middle, becoming 

 narrower and darker anteriorly. 



2 . Front narrow, its width about equal to one-third of the distance from the antennae to the ocelli ; broadly 

 sulcate in the middle and lightly carinate on the sides ; in colour shining black ; on the lowermost 

 portion covered with close-lying white pile. Eyes less densely pilose. Length 8-10 millim. 



Hab. Mexico, San Bias in Jalisco (Schumann), Acaguizotla, Dos Arroyos, and 

 Tierra Colorada in Guerrero (H. H. Smith). 



Five specimens. 



7. Cyphomyia bicarinata, sp. n. 



2 . Front broader than in C. lasiophthalma, shining black ; on each side a prominent tuberculiform carina ; 

 lower part with white pile. Antennae wholly black, clothed with black pile proximally; first joint 

 elongate; the first two joints nearly equal in length to one-half that of the third joint ; eighth annulus a 

 little shorter than the seventh, which is a trifle longer than the sixth. Face clothed with long white 

 pile, which is less abundant in the middle. Thorax, except the yellow spines of the scutellum, wholly
