sixth female segment slightly passing the center of the segment, 

 obtuse-angled at apex. Femora beneath with a longitudinal 

 groove terminated on each side by a row of spines, which in the 

 front femora is extended to the base, but in the mid and posterior 

 femora only reaches the middle, the spines gradually decreasing 

 in size toward the base. 



Length, female, 11.5 millimeters; humeral width, 3.5, 



Luzon, Laguna, Mount Banahao. 



This species is nearest to H. sugax Bredd., but is broader and 

 is readily distinguished by several structural characters. The 

 genus Homalocol'pura Bredd. is new to the Philippine Islands.

Body oblong, about or little more than four times longer than 

 broad. Head horizontal, anteocular part between eyes and anten- 

 nae and postocular part parallel-sided, a small fovea in front of 

 each ocellus and a short median longitudinal impression some- 

 what behind clypeus, the robust convex juga shortly conically 

 produced beyond clypeus, theii: inner margins almost meeting be- 

 fore clypeus, then strongly divaricate, forming a right-angled or 

 obtuse-angled sinuosity, apical half of clypeus vertical, strongly 

 widening at apex, eyes moderately prominent, seen from above 

 longer than broad, ocelli placed almost on a line with posterior 

 angles of eyes and as far from them as from one another, buc- 

 culse rather high, their anterior margin subtruncate, the inferior 

 apical angle subdentate, antennae about as long as the body, first 

 joint somewhat shorter than head and pronotum together, 

 cylindrical but elongately clavate at apex, second and third 

 joints linear, third shorter than second, fourth much the short- 

 est, rostrum reaching or a little passing base of venter, first 

 joint reaching base of head, second slightly shorter than first 

 and much shorter than third and fourth together, fourth some- 

 what longer than third. Pronotum slightly sloping from the 



' With the Leptocorixaria I unite Stal's division Micrelytraria. StS.1 

 separated them on account of the somewhat differently constructed rostrum; 

 but this character is of little importance and not constant, there being inter- 

 mediate forms that might be referred as well to one as to the other of these 

 divisions. Distant (Fauna Brit. India, Rhynch., 1, 405) has removed the 

 division Stenocephalaria from the subfamily Alydinse, regarding it as a 

 division of the Pseudophloeinae, but he gives no reasons for this absurd 

 innovation.
