502 Rey. T. A. Marshall’s monograph of 
rugose, without a medial carina. Forewings as long as the meta- 
thorax, subtriangular, furnished with a stigma near the extremity, 
3 nervures and 4 areolets (see Plate) ; hindwings nerveless, except 
a portion of the radial nervure visible towards the extremity. Legs 
red, rather stout and long. First abdominal segment nearly linear, 
hardly narrower at the base, deeply striate, the spiracles placed in 
the middle ; the following segments smooth and shining ; 2nd 
suture effaced ; apical segments very short. Terebra short, falcate, 
ascending. Length, 14 lin. 
This species was discovered to be British by Dr. 
Capron, who took several specimens in a sand-pit at 
Shiere in Surrey: the description is made from two of 
these, which he kindly gave me.

Forst., Verh. pr. Rheinl., 1862, p. 264. 
Palpi short, the number of joints differing in the two species. 
First joint of the flagellum longer than the second. Metathorax 
carinated. Radial areolet lanceolate, not reaching the tip of the 
wing ; radial nervure curved ; 2nd abscissa shorter than the 1st 
intercubital nervure ; 2nd cubital areolet not broader than long, 
measured along tbe cubital nervure ; anal nervure interstitial. 
The species are unknown to me; they are thus dis- 
tinguished by Haliday :—

Maxillary palpi short, dusky. Body deep black, shining ; man-

two smooth dorsal spaces. Wings dull hyaline ; squamule fuscous ; 
stigma blackish, narrow, emitting the radial nervure from its middle ; 
2nd discoidal areolet entirely open at the end ; hindwings very 
narrow, without a transverse vein or axillary areolet. Legs dull 
testaceous with the femora and tibie dusky, except the base of 
the latter. Abdomen oboval; 1st segment striolate, obconic.
