British Hymenoptera. 163 



short hairs, the apical margin of each segment narrowly piceous, 

 and clothed with a band of pale ochreous decumbent hairs, that of 

 the basal segment interrupted, that of the 5th and 6th segments 

 golden ; 5th segment simple ; 6th with the dorsal valve triangular, 

 its margins narrowly raised ; beneath punctured, apical margin of 

 the segments pale and clothed with pale hairs. Legs clothed with 

 golden hairs ; intermediate calcaria very long and pale, inwardly 

 serrate ; apical joints of the tarsi testaceous. Length, 9 mm. 



The (? has not yet occurred in this country, but may 

 be at once recognised by its pale antennae and the s|)ines 

 on its 6th ventral segment (for genitalia, &c., see PL V., 

 figs. 3— 36^). 



Hab. Guestling, near Hastings. Two specimens 

 taken by the Kev. E. N. Bloomfield, to whom I am 

 greatly indebted for the specimen from which this de- 

 scrij^tion is drawn up. The ? very closely resembles 

 an HaUctus, but its wings, which have only two sub- 

 marginal cells, its long narrow tongue, and simple 5th 

 dorsal segment, i.e., without the central rima, will at 

 once distinguish it.

 Very like a small Panurgtos, but with the S' narrower than the

 shorter than 2nd ; wings with two submarginal cells ; six ventral 

 segments and the tip of the 8th visible in the (J ; 7th ventral seg- 

 ment of the (J deeply cleft ; 8th very narrow and elongate ; species
