IIERMETIA.. — LUDMETA. 41 



These iusects bear no histoiy and were named " cerioides, AV'alk." 

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

 Iceta, Meij., and recortled it in my first paper on Stratiomyid^, 

 referring the remaining specimens to cerioides, Walk. A closer 

 examination reveals them all to be la^tn, as they agree with the 

 description exactly.* 



Osten-Saoken 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 kuees and white tarsi, by its blackish-brown wings, and 

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

Genotype, Hermefia marr/inata, F. ; by original designation. 



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

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

 considerable distance ; upper facets larger than lower in S , of 

 uniform size iu $ . Antennje inserted below middle line of head ; 

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

 head, cylindrical, of eight indistinct annulatious. Proboscis shoi-t ; 

 palpi small, cylindrical. Thorax rather elongate, oval iu 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 S distinct, small. Legs 

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

 venation ; discal cell triangular.

AViedemann describes the anteniioe as 5-jointed and Macquart 

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

 question of the distinctness or otherwise of the annulatious of the 

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

 specimens showing them clearly and others very indistinctly. 

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