EXOPROSOPA. 205 



The spots in insulate stand out distinctly, especially those nearest 

 the wing-border ; they are black or blackish brown, and some of 

 them are placed elsewhere than on the cross-veins. The "spots" 

 in bengalensis are small, moderately light brown infuscations, and 

 occur only on the cross-veins, although the veius themselves are 

 often lightly infuscated for considerable distances. E. brahma 

 has distinct spots, apart from infuscations of cross-veins, and 

 should therefore in this character approximate to insulata, but 

 Schiner distinctly describes the anterior part of the wing as only 

 smoke-brown. Again, in brahma the scutellum and antennae are 

 reddish yellow or brownish, whereas in both Insulata and bengalensis 

 these parts are black. The presumption is that all three are good 

 species. 



153. Exoprosopa puerula, sp. nov. (PI. Ill, fig. 9.) 



Head with frons distinctly broader at level of antennae, where it 

 is one-third the width of the head, than at vertex ; both frons and 

 face blackish, former more or less cinereous grey towards vertex, 

 latter orange yellowish around the mouth ; the lower half, or rather 

 more, of the frons and the major part of the face covered with 

 closely-applied yellowish scales and a little fine black pubescence ; 

 some yellow hairs about the lower part of the face ; proboscis 

 blackish ; antennae blackish grey ; occiput blackish, with a con- 

 siderable amount of dirty white scales, closely applied. Thorax 

 blackish, thickly covered with very thin yellowish hair-like scales ; 

 anterior border with a fringe of long brownish-yellow scales ; 

 some long bristly black hairs on lower part of prothorax ; pleurae 

 with bristly scale-like brownish-yellow hairs ; scutellum black, 

 about the apical half reddish brown, the whole dorsum (apparently) 

 covered with short yellowish scales like those of the thorax. 

 Bristles of thorax normal. Abdomen blackish, dull ; hind border 

 of segments rather narrowly brownish yellow, the colour spreading 

 out considerably towards sides of 2nd and 3rd segments ; the 

 whole dorsum covered with black hairs and closely-applied small 

 brownish-yellow scales, which towards sides of 3rd segment are 

 whitish ; a bunch of elongate pale brownish-yellow scales at sides 

 of 2nd segment and a similar bunch of shorter small black scales 

 at sides of 3rd segment. Venter yellowish, marked here and there 

 with black, and mainly covered with small yellow scales. Legs 

 black ; femora and tibiae with yellowish scales and the usual bristly 

 hairs ; tarsi black. Wings clear, the dark oblique band running 

 diagonally from tip of auxiliary vein, crossing the centres of the 

 anal and axillary cells ; a loop extending from the middle of the 

 1st posterior cell, along the outer side of the discal cell ; the colour 

 also encroaches well into the base of the 4th posterior cell ; a pale 

 yellowish spot around the anterior cross-vein and base of 4th 

 posterior cell, a semi-hyaline small spot about the base of the 

 discal cell; halteres brown ; clubs dull yellow. 

 Z/ength. 4|-6 mm.
