 Exoprosopa beckeri sp. nov. 



?. Length (8 specimens) 14 to Is-.") mm.; width of head 4 to 5-2 mm.: width 

 of front at vertex 1 to 1-4 mm.; length of wing 16 to 21-5 mm. 



Larf/e, saml-coloiired .yiec/rs, /r/f/i pair, parti-coloured wings, tips ami liivd 

 borders of a'hich are milliij : Iiead and hodij clothed excliisiveli/ with yellowish cream- 

 coloured hairs and scales, bristles on post-alar calli and hind border of scutellum also 

 yellowish ; antennal style elongate, often as long or almost as lonq as third joint of 

 antennae ; wings irith all posterior marginal cells open, and submar(/inal transverse 

 vein (recurrent vein) sinuate, not at right angles to second longitudinal vein. 



Head : Ground-colour ochraceons-rufons, lower portion of sides of face yellowish 

 horn-colonred, a spot or blotch on vertex, also jowls and basi-occipital region, and 

 sunken portion of occiput slate-coloured or blackish slate-coloured ; face only bluntly 

 conical below, not especially prominent ; horizontal portion o^ proljoscis, from orio-in 

 of palpi to tip, 4 to 4-7o mm. in length ; palpi dark brown on outer surface, and 

 clothed with yellowish hair; first and second joints of antennae ochraceous-rnfous, 

 third joint clove-brown or black. 



Thorax: Ground-colour of main portion clove-brown or blackish slate, that of 

 scutellum and ])Ost-ahir calli ciunanion-rufous or chestnut, an ill-defined roughly 

 triangular area on himl border of main portion of dorsum likewise reddish in some 

 sjiecimcns, extreme base of scutellnm occasionally blackish slate-coloured ; hair 

 on collar and u[)per part of pleurae long and dense, ground-colour of dorsum in 

 undenuded specimens entirely concealed by hair and scales. 



Abdomen : Ground-colour (which in undenuded specimens is completely con- 

 cealed in same way as that of dorsum of thorax) sometimes same as that of 

 scutellnm, except that tergites of first three or four segments each have a median, 

 transverse, iilackisli slate-coloured blotch at base ; in other cases ground-colour of 

 dorsum is mainly blackish slate, but the hind borders of the second to the sixth 

 tergites inclusive, as well as the lateral extremities of the second and third, or 

 second, third, and fourth tergites are cinnamon-rnfons. while the hind border of the 

 last tergite is ochraceons-butf, and the venter is cinnamon-rufous, with a greyish 

 clove-brown transverse band, more or less widely interrupted in the middle line, at 

 tlie base of each ventral scute, commencing with the second ; in yet other specimens 

 ground-colour is clove-brown or blacd<ish slate, but posterior angles of second and 

 tliird tergites, hind borders of third and following tergites, and tliose of all ventral 

 scutes iir(' ociiraceous-buff or bull'. 



Wings: Anterior two-thirds, from base; of wing to end of first longitudinal 

 vein, buir or cream-buff (i)roximal third or two-thirds of marginal cell, proximal 

 two-thirds or three-fourths of second basal cell, and proximal half of anal cell paler); 

 this coloured area bounded distally liy an irregular, lighter or darker, mummy- 

 brown or sepia-coloured (ilili(|ni' band, starting from anal cell just beyond middle 

 (or from axillary cell close to median i)ortion of sixth longitudinal vein), filling 

 more or less com]iIetely bases of tliird and fourth jiosterior cidls (usually o('cupying 

 a larger portion of fourth than of third jiosterior cell), occujiying jiroxiiind half or 

 rather more than proximal liall'of discal cell, forming a border along posterior side
