275. GENUS MESOCENTRUS Funkhouser 



Mesocentrus r^unkhouser. Phil. Journ. Sci, XVIII : 68i (1921). 



Characters : A single specimen, coUected by the late C.F. Baker of Los Banos, Philippine 

 Islands, and deposited in his collection, furnished the type for this genus which is represented only b}' 

 the one species. The genus is unique in showing a pyramidal dorsal crest which immediately distin- 

 guishes it from all other genera of the tribe. Head subquadrate, broader than long, roughly sculptured; 

 base strongly sinuate; eyes globnlar; ocelli small, pearly, inconspicuous, farther from each other than 

 from tlie e^-es and situated well above a Hne drawn through centers of eyes; inferior margins of gena 

 curved, edges produced forward in a slight flange; clypeus broad, extending for half its length below 

 inferior margins of genae, tip semicircular. Pronotum elevated into a single, pj-ramidal, lateralh'- 

 flattened, subtriangular dorsal crest, without branches or extensions of an}' kind; metopidium sloping, 

 strongly convex, broader than high ; median carina percurrent, only faintly indicated on metopidium 

 but very sharp on posterior process; no suprahumeral horns; humeral angles broad, heavy and blunt; 

 posterior process heavy, slightly curved, impinging on tegmina, the tip bearing a sharp, narrow, carinate 

 projection or keel on the undersurface, tip just reaching the internal angles of the tegmina; scutellum 

 present but entirely concealed by the sides of the pronotum. Tegmina subhyaline; basal and costal 

 areas coriaceous and punctate; veins prominent and strongl}' pilose; fiveapical and three discoidal cells; 

 apical limbus broad and wrinkled. Hind wings with four apical cells. Legs simple and strongly pilose; 

 hind trochanters unarmed; hind tarsi longest. 



Type pyramidatus Funkhouser. 



Geographical distribution : This genus is known only from the type species from the 

 Philippine Islands.

276. Genus DEMANGA DISTANT 



Demanga Distant, Faun. Brit. Ind. 69 (1907). 



Characters : This genus, except for the absence of suprahumeral horns bears a strong superficial 

 resemblance to the genus Teliugana Distant, but of course the absence of suprahumerals places it in an 

 entirely different tribe. It diff^ers from the other genera of the tribe Uroxiphini in having the posterior 

 process not touching the scutellum or tegmina and arising high above the base of the pronotum. Head 

 subquadrate, strongly deflexed, twice as broad as high; base nearly straight ; eyes small and globular; 

 ocelli large, prominent, about equidistant from each other and from the eyes and situated a little above 

 a Une drawn through centers of eyes; inferior margins of gense nearly horizontal and slightly curved ; 

 clypeus long, narrow, extending for more than half its length below inferior margins of gena;. tip feebly 

 bifurcate. Pronotum convex, rounded, unarmed; metopidium vertical, broader than high; median 

 carina strongly percurrent; no suprahumeral horns; humeral angles strong, conical and sharp; posterior 

 process arising high on the pronotum above the scutellum, tricarinate, heavy, gradually curving 

 downward so that the tip almost touches the tegmina, tip acuminate and reaching just bej^ond the internal 

 angles of the tegmina, about to the tip of the abdomen; scutellum entirely exposed, as broad as long.
