356 Mr, Bridgman's additions to T. A. MarshalVs 



have the hinder coxse greater part dark brown, Holm- 

 gren makes no mention of this, but says the male often 

 has the hind coxae black above, and the face is not 

 entirely yellow, but has the clypeus that colour, and a 

 broadish band is continued upwards on either side of the 

 face by the eyes. 



Mesoleptus sciitellatus, n. s. 



This insect belongs to Holmgren's division B. **, but 

 differs from any I can find described in having the 

 scutellum and post-scutellum yellow. 



Niger, abdominis medio, pedibusque rufis, coxis iiitermediis et 

 posticis nigris, scutello post-scutelloque flavo. 



Head transverse, sides oblique, slightly rounded ; clypeus widely 

 rotundate ; face finely punctate, as is the forehead ; vertex almost 

 smooth, with only rather scattered hair-pits ; antennas longer than 

 the body. Parapsides distinct ; central lobe with fine rather scat- 

 tered punctures ; lateral lobes almost smooth ; metathorax smooth 

 and shining, with no trace of areas. Spiracles of 1st segment of 

 abdomen situated in the middle, about as long or a little longer 

 than the hmd coxiE and trochanters ; 2nd and 3rd segments longer 

 than wide ; 5th the widest ; abdoiuen subclavate, about three times 

 as long as the width of the apex. Legs thicker than usual, more 

 like a Tryphon ; last joint of hind tarsi twice as long as the 4th. 

 Transverse anal nervure of wings, post-furcal, divided above the 

 middle ; the external radial slightly incurved ; areolet petiolated ; 

 recurrent nervure received almost at the apex. 



Black; mouth, clypeus, and face yellow, the latter with a 

 triangular black central mark on the upper part ; autennaj red ; 

 scape below yellow, fuscous above ; tegula- and tubercles whitish ; 

 scutellum and post-scutelluixi yellow ; 2nd, ord, and 4tli segments 

 of abdomen red ; legs red ; trochanters yellow ; coxse black, the 

 front ones yellow at the apex ; base of wings yellow ; stigma dilute 

 fuscous. Female. Length, 8*5 mm. 



I took this insect at Horning Ferry, Norfolk, on June 

 29th, 1882. By the stoutness of the legs it might pass 

 for a Trtjplion, but the 1st segment of the abdomen is 

 too slender.
