HEBMETIA.. EUJDMETA. 41 



These insects bear no history and were named " cerioides, Walk." 

 (I do not know by whom) ; and from the set I selected one as 

 Iceta, Meij., and recorded it in my first paper on STRATIOMYID^E, 

 referring the remaining specimens to cerioides, Walk. A closer 

 examination reveals them all to be Iceta, as they agree with the 

 description exactly.* 



Osten-Sa^ken notes that fresh specimens of cerioides, "Walk., 

 have green (as recorded by Walker) instead of the yellow spots in 

 dried ones, but this change after death is frequent in this family. 

 H, cerioides, Walk., differs by the legs being (presumably) black, 

 with lurid knees and white tarsi, by its blackish-brown wings, and 

 the absence of the single spot on the 5th abdominal segment. 



Genus EUDMETA, Wied. 



Eudmeta, Wiedemann, Auss. Zweifl. ii, p. 43 (1830). 

 Toxocera, Macquart, Dipt. Exot. Supp. iv, p. 44 (1849). 



GENOTYPE, Hermetia marginata, F. ; by original designation. 



Head about as broad as widest part of thorax, rather more 

 than semicircular; eyes very large, bare, contiguous in <3 for a 

 considerable distance ; upper facets larger than lower in c? of 

 uniform size in $ . Antennae inserted below middle line of head ; 

 1st and 2nd joints subequal, normal, short ; 3rd longer than 

 head, cylindrical, of eight indistinct annulations. Proboscis short ; 

 palpi small, cylindrical. Thorax rather elongate, oval in front, 

 broader behind, moderately arched; scutellum subtriangular, 

 rounded at tip, unspined. Abdomen elliptical, comparatively 

 broad at base, as long as or a little longer than thorax, flattened, 

 depressed towards tip ; genitalia in tf distinct, small. Legs 

 moderately long, thin, simple ; tarsi long. Wings with normal 

 venation ; discal cell triangular. 



Range. The Orient. 



Wiedemaun describes the anteniue as 5-jointed and Macquart 

 follows suit, both illustrating these organs ; but it seems only a 

 question of the distinctness or otherwise of the annulations of the 

 3rd joint, which is not infrequently an individual matter, some 

 specimens showing them clearly and others very indistinctly. 

 The same occurs in many individuals and species in this family. 



Table of Species. 



Shorter, brownish-yellow species ; abdomen distinctly 

 broader than thorax; 3rd antennal joint as long as 



half width of head favida, Brun. 



Elongate blackish-brown species, abdomen no broader 

 than thorax ; 3rd anteimal joint nearly as long as 

 width of head. 

 Abdominal side-margins green (in life, yellow in dried 



specimens) marginata, F. 



Abdomen without differently coloured side-margins. . 6rMwe,Meij.

 betel-nut tree at Karimganj, vii. 1918.
