enclosing a somewhat raised area. Second segment smooth, with 

 a transverse impression ; the following segments also smooth and 

 shining. Second cubital areolet petiolated, stirrup-shaped. Terebra 

 as long as the bodj'. ^ ? . Length, 2 ; wings, 3 j lin. 



Extremely like the preceding, but, besides the colour 

 of the legs, it may be known by the radial areolet, con- 

 tracted into a mere line, the curved radius following the 

 contour of the stigma ; the areolet is more distinctly 

 petiolated ; the squamulfe black ; the body shorter and 

 broader ; and the 1st abdominal segment rather narrower 

 at the base. 



Common ; generally found on Umbelliferse. Two 

 females are in Fitch's collection ; and I took a pair at 

 Niton, Isle of Wight, in 1884 ; several specimens formerly 

 in my collection have perished. 



According to Giraud bred by Fallou from Eapithecia 

 helveticaria, Boisd., found feeding upon juniper at 

 Fontainebleau.

 Black ; mandibles, palpi, mesothorax, anterior pleurae, fore and 

 middle legs, rufo-testaceous ; coxae black (anterior coxae of the ^ 

 rufo-testaceous) ; hind legs black, their femora tipped with rufous 

 and the base of their tibia; dirty white. Wings only shghtly in- 

 fumated, iridescent, with the usual hyaline streak, stigma and uer- 

 vures fuscous. Metathorax rugose. Segments 1 — 2 striolated, 

 2 with a transverse impressed hne, the apex and the reinaining 

 segments smooth and shining. Terebra as long as the thorax and 

 abdomen, c? ? , Length, 2^ — 3 lin. 



A typical species, the wings having no vestige of the 

 nervure dividing the 1st cubital areolet from the pra3- 

 discoidal. Ratzeburg says the antennae of the <? are 

 shorter than the body, but they are not so represented 

 by Curtis. Belly whitish at the base, and cariniform 

 throughout its length. Segment 1 narrowly edged with 

 pale colour at the sides and apex.
