ORDER RHYNCHOTA (HEMIPTERA) : BUGS 209 



India and is known to "bite" man, is Conorhinus rubrofas- 

 ciatus, De Geer, which hardly differs from C. megistus, being of 

 a dull dark-brown colour, with the markings on the pronotum, 

 elytra, and connexivum dusky yellow, or brick-red. It has 

 been suggested by Donovan that Conorhinus rubrofasciatus 

 is interposed in the developmental cycle of the kila-azdr 

 piroplasma. According to Distant this bug has a very wide 

 range, being found in India and the whole Oriental Region. 



Among the Reduviidae known to attack man in Africa is 

 Phonergates bicoloripes, which also has once been observed — 

 the incident is recorded by Austen — to seize and feed upon 

 an Ornithrodorus moubata — the tick that carries the spirillum 

 of African relapsing fever. It is not known, however, 

 whether this is a habit ; and even if it be a habit the issue of 

 it, so far as any possible benefit to man is concerned, may be 

 considered doubtful. Some small species of Reduviidce have 

 large transparent wings and rather resemble gnats ; among 

 them is one Asiatic species that attacks man. 



4. Family Aradid^. The bugs of this family are broad 

 and more than ordinary flat ; the connexivum is very broad

and thin ; the antenna consists of 4 segments, and the beak 

 of 3 ; the scutellum is comparatively short, and the elytra 

 have no cuneus ; the legs are of the ordinary form, and the 

 tarsi are composed of 2 segments. The Aradida are found 

 in most parts of the world living under bark and lichen, etc. 

 One large South American species, Dysodius lunatus, Fabr. 

 (Fig. 93), known in the vernacular as the " Pito " bug, is said 

 to frequent houses and to bite severely. Certain other plant
