124 Rev. T. A. Marshall's monograph of 



darker iu the ? , with a ciirved whitish streak behind the stigma ; 

 hind wings nearly hyaline ; squamulae black ; stigma, eosta, and 

 nervures fuscous, only the parastigma and praebrachial nervure 

 testaceous ; radial areolet short, broader than the stigma ; 3d 

 abscissa of the radius curved ; radius of the hind wings sinuated. 

 Head and thorax rather shining, the former finely and irregularly 

 rugulose, reticulated, partly striato-rugulose, beset with pale hairs, 

 especially on the face, which is also tranversely striated ; clypeus 

 shining, densely punctulate, discrete, the punctiform basal fovese 

 very minute ; vertex transverse, narrowed behind the eyes, cheeks 

 not dilated ; frontal fovea shining, deep, geminated. Antennae c^ 

 as long as the body, 33 — 34-jointed ; of the J shorter, 28 — 33- 

 jointed, incrassated for about f of their length, afterwards slightly 

 and gradually decreasing. Mesothorax shining, uneven, with 

 coarse irregular scattered punctures in front, striated and sub- 

 reticulated towards the scutellum, which is shining and sparingly 

 punctulate. Post-scutellum not dentiform. Metathorax short, 

 very transverse, quadridenticulate, shining, coarsely reticulated, 

 with traces of a medial carina. Abdomen dull, pubescent at the 

 apex, as long as the head and thorax, without basal carinse, 

 depresso-cylindrical, reticulated and striato-rugose at the base, the 

 striae becoming shorter and finer posteriorly, leaving the apex 

 punctulate and somewhat shining. Abdomen S obtuse and im- 

 perforate at the apex; of the ? ovate, less bluntly rounded behind; 

 terebra concealed. <? ? . Length, 1| — 2 ; wings, 3 — 3^ lin. 



Described from two males and two females. One pair 

 ■was taken by Billups, the ? is ticketed " Margate." 

 Bignell captured a t? in Devonshire, and the remaining 

 $ is in Fitch's collection. A ^ with 34-jointed antennae 

 is among some Andalusian insects brought by Sharp 

 from the Sierra Nevada. 



Having failed to clear up the obscurity surrounding 

 C. annulatus, Nees, and annidipes, Wesm., I am forced 

 to impose a new name, and probably to make a synonym, 

 for which some excuse may perhaps be found in the 

 following considerations : — 



C. annulatus, Nees, $ (wrongly called ? , and accord- 

 ing to Eeinhard =fencstratus, Nees, $ ) has 33- {i.e., 32-) 

 jointed antenna3, and is the only Neesian species to 

 which this could be referred. The femora are rufous, 

 the hind tibiae black with a white ring, and the abdomen 

 is bimaculated with yellow. It is also out of the question 

 through being coupled by Picinhard with a ? whose 

 antennae are 16-jointed, viz., fenestratus, Nees. Of
