74 HOMOPTERA 



short, not reaching the apices of the tegmina. The head is subquadrate, more than twice as broad as 

 high, with the inferior margin very much truncate and the clypeus not extending below the genffi; the 

 ocelli are small and very close together. The tegmina are long, narrow, hyaHne or smoky, with five 

 apical and three discoidal cells and are about half covered by the sides of the pronotum. However, 

 even though the tegmina are partly covered, the costal area is well enough exposed to show the three 

 longitudinal veins of the corium with the forked radius which is an important character for the group of 

 genera to which Ochrolomia belongs. The colors of these insects are various shades of brown, yellow 

 and black in rather striking combinations. 



Type suiuralis Germar. 



Geographical distribution : So far as is nowknown, this genus is limited to South America, 

 the three described species having been reported as follows : 



1. suturalis Germar, Rev. Silb. HI : 25o. 2 (i835). Brazil. 



2. tricinda Burmeister, Rev. Silb. IV : 172. 6 (i836).— Pl. 3, fig. 28. Brazil, Peru. 



3. virescens Butler, Cist. Ent, H : 338. 4 (1878). Brazil, Ecuador. 



31. Genus HEBETICA Stal 



Hebetica Stal, Hem. Fabr. H : 32 (1869). 



Characters : This was one of the seven subgenera into which Stal divided his genus Darnis 

 in 1869. All of these subgenera have since been raised to generic rank on the basis of his characters 

 which seem natural, constant and usable. The genus Hebetica was particularly distinguished by Stal by 

 the two forked longitudinal veins of the tegmina, the large anterior and very small interior discoidal cells 

 of the corium,the pubescent head and thorax and by the fact that the tegmina are almost entirely cover- 

 ed by the sides of the pronotum. In general appearance the insects are practically identical with the 

 representatives of the genera Darnis, Hebelicoides, Ochrolomia and Stictopelta. The pronotum is rather 

 rough and pubescent and is without dorsal, frontal or lateral horns or protuberances but just behind the 

 eye is a slight lobe. The posterior process is long and sharp, extending as far caudad as the tips of the 

 tegmina. The tegmina are long, narrow, hyahne, with two longitudinal veins, both forked near the 

 center of the corium. Unfortunately, so little of the tegmen projects below the lateral margins of the 

 pronotum that it must be pulied out before this important character can be seen. The head is broad, 

 with the ocelli about equidistant from each other and from the eyes. 



Type limacodes Burmeister. 



Geographieal distribution : According to present records, the genus is represented only in 



South .'\merica by the following species : 



1. apicalis Fairmaire, Rev. Memb. 483. 23 (1846). Brazil. 



2. arechavelata Goding, Ent. News XXV : 400 (1929). Uruguay. 



3. coiwoluta Fabricius, Spec. Ins. II : 3i8. 14 (1781). Brazil. 



flavicincta Germar, Mag. Ent. IV : 12. 2 (1821). 

 atomaria Germar, Mag. Ent. IV : 12. .S (1821). 

 cuneata Butler, Cist. Ent. II : 341. 2 (1878). 



4. limacodes 'B\ixme\ster , Rev. Silb. IV: 12. I75(i836). Brazil, Colombia.
