picke, but not to the Bombylidae. The almost complete oblitera- 

 tion of the first section of the fourth vein finds its parallel in the 

 Empid genus Syndyas, but so far as I am aware, is not known to 

 occur in any Bombylid genus. The course of the second vein, 

 closing the marginal cell, is a character not known to me as oc- 

 curring in either of the above-mentioned families. Still, this 

 character, as well as the other neurational ones, cannot be con- 

 sidered of sufficient importance to exclude the present form from 

 the Empidae, and it will best be located in the subfamily Hybotinae. 

 The following is- a description of this new form: 



MYTHICOMYIA n. gen. 



Body destitute of macrochsetae. Head globular, attached to a 

 distinct neck. Antennae porrect, two-thirds as long as head; 

 first joint very short, the second as broad as long; third joint 

 broadly lanceolate, not annulate, nearly three times as long as 

 the second; style terminal, nearly half as long, and one-third as 

 broad as the third joint, very densely pubescent. Eyes of the 

 male contiguous, and with an area of enlarged facets above. 

 Three widely separated, equidistant ocelli present. Proboscis 

 rigid, nearly as long as heighth of head, projecting obliquely 

 forward, destitute of labellae; palpi minute. Thorax greatly 

 arched, in profile higher than long. Wings having the marginal 

 cell closed; onfy one submarginal and four posterior cells, all of 

 them open, as is also the anal cell; first section of the fourth vein 

 colorless, the last, or seventh vein, very weak. Neuration as 



shown in the accompanying figure. 



Legs rather robust, but none of the 

 parts dilated, destitute of bristles, spines 

 and other processes ; front coxae less 

 than half as long as their femora; pul- 



MVTHICOMVIA RILEVI. vilH well-developed , empoclium bristle- 

 like. (Name from the Greek Muthikos, legendary, and mnia, a 

 fly.) 



Mythic comyia rileyin. sp. Black, the frontal triangle, face, humeri, base 

 of the first and apices of the otlu-r abdominal segments excepting the last, 

 apex of femora, tibia- wholly, and tin- halt<-rrs white, the short, sparse 

 hairs also white; occiput, thorax and abdomen gray pollinose, the hypo- 

 pygium shining, one and one-third times as high as long, shorter than, 

 but projecting one-fourth its height above the eighth abdominal segment. 

 Wings uhnllx hyaline. Length ,?..s mm.
