44- Orthorrhapha brachycera. 



jointed style). Legs more or less strong. Wings somewhat broad; 

 the subcostal ceil elosed; two cubital cells (rarely, in non-Danish 

 genera, three); between the discai cell and the upper branch of the 

 postical vein a postical cross-vein; the fourth posterior cell elosed at 

 some distance from the margin, the first sometimes narrowed, or (in 

 non-Danish genera as Andrenosoma, Hoplistomerus) elosed; anal cell 

 elosed. 

 Only one genus 7. Laphria. 



7. Laplipia Meig. 



Large or middle sized species of black colour, sometimes with 

 reddish markings; they are often strongly pilose and then the pile 

 may give rise to pale designs. Head narrower than, or as broad as, 

 thorax, broader than high; it is short and the posterior surface flat. 

 Face rather broad with a large cailus which does not reach the an- 

 tennæ; the epistomal beard occupies the whole cailus and there are 

 shorter hairs continuing up to the antennæ. Antennæ inserted near 

 to each other, considerably above the middle. Jowls a little descen- 

 ding below the eyes. A pair of ocellar bristles more or less distinct 

 among the other hairs on the vertex. Antennæ consisting of three 

 joints, the first about twice as long as the second, the third the 

 longest, slightly compressed, blunt at the apex without style or arista. 

 The eyes have the facets in the front part, from the inner margin 

 outwards, somewhat enlarged. The united stipites of the maxillæ 

 lie on the back of the head, below the occipital foramen, surrounded 

 by a connecting membrane. Glypeus distinctly marked off, rounded 

 upwards, and impressed. Proboscis about as long as the head 

 is high, directed forwards and a little downwards; labium rather 

 characteristic ; it is straight, at the base thick and swoUen but for 

 the rest it has the upper and lower margin parallel and is strongly 

 compressed ; the apex is trunctate ; the basal i)art is very short, much 

 shorter than the apical part, this latter shows no division into two 

 joints; there are long hairs below at the base and short hairs at the 

 apex. Labrum short, slightly longer than the basal part of the labium. 

 The maxillæ are long, pointed and slightly curved towards the apex; 

 the maxillary palpi are two-jointed. Hypopharynx rather long, 

 straight and pointed, it is densely beset with somewhat short hairs 

 above over more than the apical half. Maxillæ and hypopharynx 

 equal in length to the labium. Thorax rectangular, moderately high, 

 arched above. In some species no macrochætæ are discernible, in 

 others præsutural, supraalar and postalar bristles are present; the
