228 Mr. J. O. Westwood's Descriptions 



Megischus annulator, Brulle, Hist. Nat. Ins. Hym. iv. p. 539. 



pi. 40, fig. 5. 



Niger, alis subhyalinis, abdominis segmento 2do toto laevigata, 

 terebrae valvulis ante apicem annulo albo. 



Long. corp. 0,0i0 ; long, oviduct. 0,055. 



Habitat unknown. Coll. Mus. Hist. Nat. Paris. 



The cheeks of this species are marked with a red spot ; the 

 mandibles in part ferruginous, as well as the anterior part of the 

 prothorax. The scutellar region is entirely smooth ; the meta- 

 thorax marked with some large punctures, transversely strigose 

 behind, and slightly so in the middle; the first segment of the 

 abdomen is very finely strigose transversely, the remainder are 

 smooth, the second alone presenting one or two strigae at the 

 base. The figure of this species is very unsatisfactory, not repre- 

 senting the white bar of the valves of the ovipositor, and giving 

 four joints to the posterior tarsi.

Hym. iv. p. 539? 

 I have been obliged to add a query to the last citation, as M. 

 Brulle describes the insect thus : " Niger, alis fere fuscis, abdominis 

 segmento 2ndo laevigata, valvulis terebrae nigris. Long. corp. 

 0,030 ; long. ovid. 0,040. Cette espece ressemble beaucoup a la 

 precedente. Elle n'en difFere, pour ainsi dire, que par sa taille 

 moindre, par la couleur plus foncee de ses ailes, et par les valves 

 de sa tarriere, qui sont plus greles, sans anneau blanc, et dont 

 l'extremite n'est pas lanceolee comme dans le M. annulator." In 

 the original description in the Encyclopedic Methodique, as well as 

 in Guerin's figure, the valves of the terebra are however marked 

 with a white bar near the tip, so that either M. Brulle has de- 

 scribed another distinct species, (which seems improbable, as he 

 refers to M. Serville's cabinet,) or the specimen must have had 

 the extremity of the valves of the terebra broken off, and this 

 seems the more probable from what M. Brulle says respecting 

 their tips not being lanceolate. M. Brulle also describes the 

 cheeks as being marked with a red spot, and the mandibles as 

 ferruginous at the base.
