28o HOMOPTERA 



the base of the head. Head subquadrate, wider than long, not tuberculate; base lightly arcuate and 

 weakly sinuate, smooth; eyes large and ovate; ocelli large, prominent, equidistant from each other and 

 from the eyes and situated about on a line drawn through centers of eyes; inferior margins of genae 

 sloping and rounded; clypeus much deflexed, extending for two-thirds its length below inferior margins 

 of genae, weakly trilobed with the median lobe much the largest, tip pointed. Pronotum low and 

 convex, unarmed; metopidium sloping, broader than high; median carina percurrent; no suprahumeral 

 horns; humeral angles heavy, broad and blunt; posterior process straight, tricarinate, tectiform, arising 

 from upper posterior margin of pronotum and extending backward close to scutellum and tegmina but 

 not touching either, tip acuminate and reaching to the internal angles of the tegmina; scutellum entirely 

 exposed, triangular, hirsute, broader than long, tip broadly bifurcate. Tegmina long, narrow and 

 subhyaline; base narrowly coriaceous and punctate; veins very heavy ; five apical and two discoidal 

 cells; apical limbus well developed. Legs short and stout ; hind tarsi longest. 



Type monianus Jacobi.

279. Genus OCCATOR Distant 



Occator Distant, Faun. Brit. Ind. App. 174 (1916). 



Characters ; If this genus is to be separated from the preceding genus, it must be done solely 

 on the basis of the upturned end of the posterior process, a very dangerous character on which to 

 establish a genus, since such a character might so easily represent a mutilation ordeformity, conditions 

 which are very commonly seen in the family particularly in the posterior process. Every other character 

 which Distant gives for the genus is common to many of the genera of the tribe. It is to be noted, also, 

 that the geiius is established on a single species and, so far as is known, on a unique type specimen. 



We have never seen the one species which represents Occator but are tentatively accepting the 

 genus entirely on the authority of its author, quoting his description and reproducing his figure. 

 Distant's original description of the genus is as follows : 



« Scutellum complete; pronotum subglobose, lateral angles only obsoletely produced, the 

 posterior process moderately slender, well separated from the scutellum, the apical area strongly 

 upcurved, tricarinate, apex not passing the posterior angle of the inner tegminal margin, the 

 central carination percurrent throughout its entire length; tibiae not dilated; tegmina with the 

 apicalcells nearly straight; ocelli much nearer eyes than to each other; front with two tubercles 

 near its posterior margin. 



» In this enumeration allied to the genera Machaeroiypus and Detnanga, but distinct by the 

 shorter and peculiarly upturned posterior pronotal process. » 



Type erectus Distant.
