Mimomyia hispida, Theo. (figs. 11, 12). 



The larvae are grey in colour in life, and while resembling the larvae of M. inimomyia- 

 formis in configuration, are of a much lighter colour. 



The head is large, the antennae having a similar peculiar outwardly directed 

 appendage to that possessed by the lan^a of M. mimomijiaformis ; this portion is 

 much lighter in colour than the basal portion and the spicules which cover the base 

 are absent. Two long bristles occur at the junction of the apical with the basal part.

The hair-tuft is situated at about three-fifths of the length of the basal portion of the 

 antenna and is formed of plumose hairs. All the frontal hairs are markedly plumose 

 and there is a bifurcated subplumose hair of considerable size projecting laterally 

 from the head in front of the eye. The palp is large. The long thoracic and abdo- 

 minal hairs are strongly plumose. The comb is formed of two rows of spines in 

 arched lines, the posterior row consisting of 5-7 large, the anterior of about twenty 

 small spines. The subsiphonal plume is composed of plumose hairs, the hairs of the 

 siphonal and the anal plumes being pubescent. There are many stellate hairs on the 

 abdominal segments. The siphon is six times the length of its diameter at the base, 

 there being three or four feebly developed spines in a horizontal row at its base 

 ventrally and a strong tuft of simple hairs inserted well before the middle. The 

 anal segment is longer dorsally than ventrally and its posterior edge is markedly 

 spinose. The dorsal hairs are collected into strong tufts, while the ventral beard is 

 feebly developed, and there is laterally a long subplumose hair. The anal papillae 

 are about as long as the anal segment.
