88 HOMOPTERA 



cephalic margin of the metopidium; eyes large and glassy; ocelli minute, located in the upper outer 

 angles of the head, very close to the base and to the eyes; inferior margins of the genas projecting down- 

 ward in lobes on each side; clypeus very long and narrow and projecting for two-thirds its length below 

 the inferior margins of the genae ; the extended cl}'peus and the lobes of the gense giving the head a tri- 

 lobed appearance. Pronotum rounded above the shoulders and extended forward in a long, slender anter- 

 ior process which is strongly curved upward and ends in a slightly dilated and bifurcate tip; humeral 

 angles very weak, obtuse and triangular; median carina percurrent; posterior process long, slender, 

 tricarinate, decurved, tip acuminate and extending just to the tips of the tegmina; scutellum entirely 

 concealed. Tegmina long, navrow, entirely free, opaque but with veins raised and prominent; five api- 

 cal and three discoidal cells; median apical cell truncate at base ; apical hmbus well developed. Legs 

 simple and very slender ; hind tarsi the longest. 



Geographical distribution : Known only from the following single species from the West 

 Indies :

51. GENUS HEMIPTYCHA GERMAR 



Hemiptycha Germar, Rev. Silb. I : 177 (i833). 

 Hypseletropis Stal, Hem. Fabr. II : 26 (1869). 

 Gelastophara Kirkaldy, Ent. XXXVII : 279(1904). 



Characters : This genus has had a rather strange and troubled history and is here included only 

 because the type species, which is now the only species remaining in the genus, still remains as the lone 

 representative, with characters which seem to distinguish it from related forms. The meager characters, 

 as described for the genus by Germar, have been subject to many interpretations, and doubtless to many 

 misinterpretations, so that species have been assigned to the genus and afterwards removed to other 

 genera in a fashion which is most confusing. At one time or another, sixty four difFerent species have 

 been placed in Hemiptycha; now only one remains. Moreover, at least two synonyms are known for 

 the genus; five or six new genera have been split off from these groups; a number of the old species 

 have been positively shown to belong to other subfamilies; and the synonymy of many other species, 

 formerly placed in Hemiptycha, is questionable. 



The chief character which may validate the genus is the position of the pronotal hom far back 

 on the pronotum and arising from behind the humeral angles. The only other diagnostic characters 

 seem to be the very weak humeral angles which are not produced into spines, the straight anterior 

 process and the truncate median apical cell of the corium, and these characters have therefore been used 

 to identify the genus in the preceding synoptic key. 



Type obtecta Fabricius. 



Geographical distribution : The single species now remaining in the genus was described 

 froni some unidentified locality in South America. We have never seen this insect and we know of 

 no one who has recognized it since Stal used it as the type of Hypselotropis (which we beheve to be a 

 synonym of Hemiptycha) in i86g.
