 The only species with which this can be confused is C. tigripes, which is larger, 

 and has an unhanded proboscis and more numerous spots on the legs ; the 

 thoracic scaling is also quite different. C. (juasigelidus has a very distinct 

 appearance, as might be supposed from £he fact that three genera have been 

 erected for its special benefit. One of these, Lasioconops, was founded on a 

 specimen which had a number of scales of some Lepidopteron adhering loosely 

 to its abdomen. Some specimens of Pseudoheptaphleboviyia sent to the British 

 Museum by Dr. Ventrillon are undoubtedly this species. In this and the two 

 following allied forms the jjale front two-thirds of the thorax is often more 

 marked in the c? than in the Q ,
