lateral margins converging evenly to the acute apex; ventral 

 surface convex, rugulose, showing an indication of medio-longi- 

 tudinal angulation, basal spine prominent, slender, with apex 

 rounded, separated from frontal fastigium by a space greater than 

 its width, which in lateral aspect is rounded. Head with occiput 

 and genae weakly rugulose, face more strongly so. Pronotum 

 heavily rugulose, disk flattened and separated from lateral lobes by 

 heavy and blunt lateral carinae. Tegmina and wings fully de- 

 veloped, the former rounding rather sharply at apex. Mesosternal 

 lobes acute-angulate produced. Subgenital plate acute-angulate 

 emarginate meso-distad, the lateral portions thus formed truncate 

 distad, each surmounted by an elongate, straight, very slender, 

 cylindrical style, nearly five times as long as its greatest width. 

 Femora with dorsal surfaces all showing low, rounded, very broad, 

 transverse rugae. Caudal femora very slender. Ventral femoral 

 margins armed as follows. Cephalic internal 4 and 5, cephalic 

 external 6 and 7, median internal 5 and 6 (some of these minute), 

 median external 5 and 6, caudal internal 12, caudal external 13. 



General coloration tawny olive, finely mottled with brown and 

 immaculate, except for a blackish line on proximal portion of the 

 ventro-external margins of the caudal femora, a fleck of the same 

 at the distal extremity of each auditory foramen of the cephalic 

 tibiae and a number of dark brown flecks on the tegmina. 



Length of body 39, length of fastigium of vertex 4.8, length of 

 pronotum 9.9, caudal width of pronotum 6.2, length of tegmen 49, 

 length of cephalic femur 10.3, length of caudal femur 22, greatest 

 width of caudal femur 2.4 mm. 



The type is unique. It constitutes the first record for the genus, 

 as at present limited, from the Philippines. 



EUCONOCEPHALUS Karny

 pp. 4 and 39. 



Karny proposed this name as of subgeneric rank, but it has 

 subsequently been given full generic recognition. Here we find 

 an array of species, some of which are extremely plastic and many 

 of which are exceedingly close in relationship. The treatment by 

 Redtenbacher in his "Monographie der Conocephalidarum" is 

 superficial, dogmatic and confusing. The work of several earlier 

 authors was ignored and a multitude of species described, the 

 validity of many being more than doubtful. Even the characters 

 used are in many cases of questionable value, particularly those of 

 coloration. 



It is much to be regretted that Karny, in his "Revisio Cono- 

 cephalidarum," made no effort to clear up the numerous Redten- 

 bacherian errors. Though insufficient material of Eueonocephalus
