shorter than head and pronotum together, first joint a little pass- 

 ing apex of head, second and third joints gradually somewhat 

 inerassated from base to apex, subequal in length or third 

 slightly shorter, fourth much longer than third. Rostrum reach- 

 ing fore coxse. Pronotum in the male with the greatest width 

 before the middle and with the lateral margins more or less 

 strongly rounded except near base, where they are straight and 

 subparallel, in the female with the greatest width behind the 

 middle, subparallel from base to middle, then rather strongly 

 narrowed (but scarcely rounded) to apex, in both sexes im- 

 punctate, finely palely pubescent, the transverse impression al- 

 utaceous, the anterior lobe in the middle with two fine impressed 

 longitudinal lines placed very near each other, the basal margin 

 broadly but not deeply sinuate. Scutellum with a smooth me- 

 dian keel in the apical half. Elytra usually reaching base of 

 last dorsal segment, sometimes a little shorter. Mesostemum 

 convex, without a median impression. Orificia straight, directed 

 a little obliquely forward, reaching middle of metapleura. Abdo- 

 men alutaceous, fourth ventral segment of female extremely 

 short in the middle. Front femora in the male more inerassated 

 and more spinous beneath than in the female ; hind femora some- 

 times obsoletely spinous beneath. 



Length, male and female, 5.6 to 7 millimeters. 



Luzon, Laguna, Los Baiios and Mount Maquiling. 



Readily recognized by the structure and the sculpture of the 

 pronotum and the distinct, well-defined white markings of the 

 black elytra. 



Pirkimerus parviceps sp. nov. 



Narrow, linear, shining, piceous-black ; basal border of pro- 

 notum often dark testaceous, elytra opaque, dark brown with 

 blackish veins; commissure of clavus, an oblong subbasal costal 

 spot to corium, an oblong spot at exterior basal angle of mem- 

 brane, and a similar more or less distinct spot opposite at in- 

 terior margin of membrane luteous; antennae (except the fus- 

 cous apical joint), rostrum, and front legs testaceous, middle 

 legs brownish testaceous, hind legs piceous. Head smooth, longer 

 than broad, as broad as half the basal width of pronotum, eyes 

 moderately prominent, seen from above much longer than broad, 

 ocelli subcontiguous to eyes, antennae as long as head and half 

 the pronotum together, first joint linear, slightly passing apex of 

 head, second and third somewhat inerassated from base to apex, 

 subequal in length, each distinctly longer than first, fourth as 

 long as first and second together and thicker than the others.
