Orthoirhaplia hrachycera. 



clypeus sliort; prol)Oscis very shoit; laJjrum aiici hypopharynx short 

 and small, the first semitubular, the latter rudiinontary: the laliella 

 lii'oad, protnidiiig somowhat forwards, generally of wliitish colour; 

 when spread out they form a disc : there are only small basal pieces 

 of the maxillæ and small , one-jointed or indistinctly Iwo-jointed 

 maxiilary palpi. Tliorax is longisli, broadest behind; scutellum without 

 spines. Abdomen is long and rather narrow, at the base narrower 

 than the thorax, broadest behind; it consists of live segments. The 

 male genitalia have a pair of small styles in the middle and a thick 

 lateral lamella on each side; the female genitalia show^ apair of small, 

 two-jointed styli. Wings rather long and broad; radial vein present 

 cubital vein forked, from the discai and second basal cell rise four 

 veins, the fourth being Ihe anterior branch of the postical vein, thus 

 there are five posterior cells; between the discai cell and the postical 

 vein there is a postical cross-vein. In rest the wings lie parallel over 

 the abdomen. 



The larvæ are elongate with nearly parallel sides, not tapering 

 behind, tlattened; the head is conical and not distinctly cleft in lobes. 

 it has a somewhat bulbous swelling with an eye on each side towards 

 the base; the segments are much broader than long, the last segment 

 is rounded behind, it is somewhat flat above with a 

 sliield-sliaped impression, the incisure between the two 

 last segments is curved ; the last segment liears the 

 anus on the under surface as a longitudinal split. 

 The segments bear a transvorse row of about six 

 ralher long bristles on each surface, and besides a 

 few l)ristles at the margin; the last segment bears 

 sonie bristles on the margin, and the head and pro- 

 thorax bear several bristles. There are prothoracic 

 and soven pairs of abdominal spiracles, i)nt they are 

 extremely small: I could dctecl no nietathoracic 

 spiracles; above al the apex of the last .segment there 

 is a transverse split with terminal spiracles. 



The larvæ live in dung, in the earlli in gardens 

 Fig. ^4. Larva of and upou the wliole in rich soil; they hibernate and

The species of Sargus are more lively than most of the other 

 Stratiomyids, and they fly often and hower in the sunshine; they 

 occur nearly everyvvhere and are often seen in gardens, howering 

 around flowers and in bushes. 



Of the genus 13 species are known from the palæarctic region of 

 which 3 hithertho have been found in Denmark.
