lines, and pink lateral edges. Anterior border of pronotum with a 

 short pink spine on each side. Corium dark brown with some pink 

 at the base ; membrane light brown. Connexivum brown with light 

 pink stripes extending for a short distance round to the ventral

The egg of sanguisugus is similar to that of nibrofasciatus. The 

 early stages, which have been described and figured by Kimball and 

 Marlatt, are very similar to those of the Oriental species. In America 

 the adult insect is called ' the blood-sucking Cone nose ' or sometimes 

 the 'Texas bed bug.' It conies into houses, but its normal food appears 

 to be the body juices of other insects ; it has been seen feeding on the 

 bed bug, Cimex lectularius. Kimball found it in poultry houses and 

 horse stalls. Marlatt states that the bite of this bug often causes severe 

 constitutional symptoms. In a recent paper Morrill states that in many 

 parts of Arizona sanguisugus takes the place of Cimex lectularius and is 

 common in houses. 



Neiva records a variety ambigua from Florida, U.S.A., which is smaller 

 and paler than the type ; the stripes on the connexivum are more of 

 an ochraceous colour. 



Conorhinus uhleri, Neiva. General colour dark mahogany. Head, 

 including proboscis and antennae, of the same colour. Pronotum dark 

 brown, lighter on the tubercles and sides ; there are two admedian 

 raised lines on the pronotum which diverge posteriorly. Scutellum 

 dark brown, apex light. Corium dark brown with light markings at 

 the base. Connexivum with dark spots not reaching to the edge. 

 Ventral surface of the body dark brown ; legs light brown. In the 

 male the spots on the connexivum are not so well marked as in the 

 female, and its general colour is much lighter. 



This species is found in Texas, Arizona ; Tugson, Oracle, Hot- 

 spring Sta. Catalinia, California ; San Diego. New Mexico, Messila 

 Park. It is said to frequent human houses and to suck blood. 



Conorhinus neotomae, Neiva. Proboscis reddish brown ; antennae 

 dark brown, last segment light. Anterior lobe of pronotum a little 

 accentuated ; the posterior angles with light spots ; median portion with 

 two raised ridges diverging posteriorly. Scutellum dark brown through- 

 out. Corium dark brown with a red spot in the middle, and another 

 situated at the apex ; membrane dark. Connexivum with black dots 

 and light reddish brown streaks. Femora light brown with a reddish 

 tinge ; the tarsi the same.
