538 FAMILY XIX. — REDUVIHLE. 



dd. Ocelli placed in front of a transverse line connecting the hind 



margins of the eyes; second joint of antennae composed of many 



small segments united. Subfamily VII. Hammacerin^e, p. 562. 



cc. Elytra with a quadrangular or discoidal cell at the base of the 



membrane; front and middle tibiae without a terminal plate. 



g. Ocelli farther apart than are the eyes; apical halves of front and 



middle tibiae swollen and grooved to receive the retractile tarsi ; 



form oval, robust, the sides of abdomen curved. 



Subfamily VIII. Apiomerin^e, p. 564. 



gg. Ocelli not as far apart as are the eyes; apical halves of front and 



middle tibiae not swollen or grooved ; form slender, ovoidal or 



oblong, the sides usually subparallel. 



h. Front lobe of head longer than hind one; anal area of membrane 



not extending as far forward as does the costal cell; basal 



joint of antennae thickened, and in repose porrect, the other 



joints usually very slender, folding back beneath it and the 



head. Subfamily III. Stenopodin^e, p. 542. 



hh. Front lobe of head (except in Rhynocoris) not longer than hind 



one; anal area of membrane extending farther forward than 



does the costal cell; basal joint of antennae slender, rarely if 



ever porrect. Subfamily IX. Zelin^e, p. 566. 



Subfamily I. CARTHASIN^ subfam. nov. 



Small slender spindle-shaped species having the front lobe 

 of head subcylindrical, much prolonged in front of eyes, hind 

 lobe oblong, its sides subparallel; ocelli wanting; pronotum 

 unarmed, its front lobe subcylindrical, much longer than wide ; 

 front coxae nearly one-half the length of femora ; tibise all end- 

 ing in a short lobe at apex which is spongy beneath ; tarsi 1- 

 jointed, the claws simple, divergent. 



This subfamily is founded to receive the genus Carthasis 

 Champ. (1900, 305) and its synonym, Orthometrops Uhl. (1901, 

 508). Champion placed his genus in the family Nabidse, from 

 which it differs widely in its form of body, lack of ocelli, pres- 

 ence of a transverse groove between the eyes, short stout 

 curved beak, form of pronotum, long front coxse and 1-jointed 

 tarsi. Its beak, which is 3-jointed, not 4-jointed as stated by 

 Champion, the form of body and the interocular groove are 

 Reduviid-like in character, while the lack of ocelli, long front 

 coxae and 1-jointed tarsi ally it with the Ploiariidae. It is, in 

 my opinion, a sort of connecting link between these two fam- 

 ilies and Uhler was much nearer right when he placed his 

 Orthometrops in the Saicida (subfamily Saicinae of the Reduvii- 

 dae) than was Champion in referring his genus to the Nabidae. 

 In this placement Uhler was followed by Fracker (1913, 225).
