XEW AND KNOWN AUSTRALIAN SARCOPHAGID FLIES. 189 



Female. 

 This differs from the male in the following respects : — 

 Frontal stripe about as wide as parafrontals. A row of 

 eight frontals beside frontal stripe, three others outside 

 these and converging upon them above. Thorax as in male ; 

 apical scutellars absent ; scutellum not so elongated as in 

 male and possessing an almost semicircular shape. Abdomen 

 clothed with short black reclinate bristles and a few large 

 ones above ; hairless ventrally. General colour silvery, the 

 black markings very restricted and indistinct. Dorsal 

 median black stripe practically absent. 



Described from five imperfect specimens obtained from 

 "plague locusts" {Pachytylus australis Br. = Chortoicetes 

 tenmnifera Walker) from the following localities in New 

 South Wales: — Whitton, Wagga, Cooma, Corowa. (Skuse, 

 Ollitf, and Froggatt material.) 



The species was In-ietiy described by Skuse in 1891 in 

 an article by Olliff (Agric." Gaz., N.S.W., 1891), who adderl 

 figures of the entire fly, the antenna and puparium. It was 

 subsequently stated by Cocpiillet (1892) and by W. W. 

 Froggatt (1907) to be a Sarcophaga. To the latter autho'. 

 wo are nnich indebted for the opportunity to examine 

 Skuse 's type material (from Wagga and Corowa) which 

 is in his possession. 



The characters of the species, as given in the above 

 description, show that it cannot lie placed in the genus 

 Sarcophaga. We have not been able to assign it to any of 

 the other genera belonging to the family Sarcophagida». 

 We have accordingly erected for its reception the new 

 genus Locnstivora whose characters may be defined as 

 follows : — 



A small, but fairly robust dark grey and black species. 

 Thorax with the usual three longitudinal lines; the acces- 

 sory median lines more than usually distinct. Front in 

 male very narrow, eyes nearly four-fifths the height of 

 head ; but in the female the frons is considerably wider than 

 in the male. Third antennal segment only a little longer 

 than second. Arista plumose on proximal third only. 

 Epistomials and facials few in number. A single row of 

 weak parafrontal bristles. Legs devoid of hair, but moder- 

 ately well supplied with bristles. Cell 5R of wing almost 

 closed. Only vein R 4 -]- 5 hairy. Abdomen hairless.
