of Nematus. The head is yellow, with black eyes, and a black spot 

 spreading out from the vertex to between the black antennae, and 

 extending to the eyes. The upper jaws are pale brown at the points. 

 Farther, the entire body is gamboge-yellow (not orange), with the fol- 

 lowing exceptions : — A large round shining black spot covering the 

 four lobes on the back of the mesothorax ; a transverse line below the 

 white cenchri on the metathorax ; a brownish black spot, sometimes 

 but faintly indicated, on the breast of the mesothorax before the place 

 of insertion of the intermediate pair of legs, the tips of the tibiae and 

 the tarsi of the last pair of legs. 



The wings are large and yellowish ; stigma black, as also the costal 

 nervure, except at the insertion, where it is yellow. The membrane 

 between the costal and postcostal nervures is brown ; the other nervures 

 are black, except the anal nervure, which is yellow. 



It appears from what has been said above that this insect produces 

 more than one generation in the year; it also appears that the last, 

 probably the third, is the most numerous. I have seen specimens from 

 Holland, Zealand, Utrecht, Gelderland and North Brabant: it appears 

 to be nowhere scarce. I am, as yet, unacquainted with its parasites. 



I have omitted any reference to the description contained in J. L. 

 Frisch's ' Beschreibung von allerlei Insecten Teutschland,' &c., 

 Part vi. No. 4, and Vol. iv., although it is probable that he partly 

 had our species in view ; and 1 have made this omission, in the first 

 place, because he appears to have confused it with Hylotoma Rosje, 

 and, in the second place, because his description is extremely in- 

 accurate, especially his representation of the nervures of the wing, 

 which cannot apply to this species or even to the genus Nematus.
