in 2 5 fl'i't, with linear (loewii) or diverging (przewalsJci/i) sides ; 

 three ocelli. Eyes small, bare, facets of uniform size, with a very 

 di.stincfc shining smooth margin round lower half. Anteimai 

 small ; 1st joint hardly visible, 2nd bowl-shaped, broader above 

 than below, rather irregular ; 3rd joint llatly biconvex, oval heart- 

 shaped, irregularly sinuate in outline ; arista thickened basally, 

 ratlier long, bare, placed on the sunken, lenticular flattened space 

 on the outer side of the 3rd joint (loewii), or on tiie inner side of 

 the outer part of the 3rd joint {przewalskyi) *. Face triangular, 

 flat, not projecting beyond base of antennae; cheeks greatly 

 developed, wrinkled, extending downwards to a distance fully 

 equal to height of eyes, distinctly sunken in middle, jjrojecting a 

 little hindwards on lower part. Mouth-opening small, triangular ; 

 proboscis and palpi rudimentary. Thorax very thick, weil curved, 

 almost broader than long, much narrowed in front ; scutellum of 

 medium size, semicircular. Abdomen shortly-ovate, as broad as 

 thorax, thick, well curved, 4-segmeuted (loewii) or o-segmented 

 {j>rzewalslcyi) ; genitalia concealed. Legs moderately long and 

 strong, hind pair rather longer; all femora thickened at base 

 {loewii) or hind pair only (przavalshyi) ; hind tibiae narrowed at 

 base. TI7/(/ys : 1st longitudinal vein ending a little beyond 

 auxiliary vein ; 2nd long, parallel to and rather approximate to 

 3rd, ending a little before the apex of the latter (which in its turn 

 ends appreciably before the wing-tip), very slightly curved. 

 Anterior cross-vein opposite apex of auxiliary vein (pi-zewalski/i) 

 or distinctly beyond it (loeivii), and at middle of discal cell ; 1st 

 posterior cell closed on wing-border (loewii) or shortly petiolate, 

 its outer side nearly parallel with the hind margin of the wing ; 

 2nd basal and anal cells subequal, sliort ; 5th vein reaching margin 

 of wing; 6th becoming very weak in its last section but attaining 

 the wing-margin. All the veins distinct except the 6th. Alulae 

 small, with rounded tips ; alar squamae small, thoracic squamic 

 mucli larger, both pairs with a distinct margin, the latter pair dis- 

 tinctly wrinkled.

Lifc-histori/ unknown . 



This genus was established by Schnabl for Microeej>haliisi loewii, 

 a new species from the neighbourhood of Jenisseisk, West Siberia, 

 and he noted its affinity to Ilj/poderma. Since the generic name 

 was preoccupied in Reptilia, C'oleoplera and Diptera, the genus 

 Avas renamed by Semenov. Brauer considers the genus f to be 

 related to Hypoderma, Cepludomyia Viwii Gastropldlus. Five species 

 are known.
