basal angle, the outer vein in its basal part parallel to the basal 

 margin, then rotundately bent and proceeding to the apex, the 

 straight median vein arising from near base of outer vein. 



In Distant's figure of the type the membrane is represented 

 as having two basal cells. This is indubitably due to faulty 

 tracing of the veins, which are somewhat indistinct in certain 

 specimens. 



The front femora are usually armed with one or two spines 

 beneath, but this character cannot be relied on, as the spines 

 are often very feebly developed or wanting. 



Some of the distinctive characters of the six Philippine species 

 may be summarized thus: 



Key to the Philippine species of Sadoletus. 



a\ Corium entirely whitish, its apical margin but slightly shorter than the 

 claval suture, the uniseriately punctate basal part of the exocorium 

 much shorter than the remaining part. Femora whitish testaceous. 



valdezi sp. nov. 



a'. Corium not entirely whitish, its apical margin very distinctly shorter 



than the claval suture, the uniseriately punctate basal part of the 



exocorium subequal in length to the remaining part. Femora not, or 



not entirely, whitish testaceous. 



b\ Corium whitish, somewhat less than apical half black. Rostrum not 



reaching base of venter. 



c\ Pronotum not entirely black. Larger species (about 5 millimeters). 



d\ Posterior lobe of pronotum nearly twice the length of anterior 



lobe, tawny, brown-punctured. Scutellum black with tawny 



apical part and ochraceous median keel. Ground color of legs 



castaneous bakeri sp. nov. 



d'. Posterior lobe of pronotum cne-half longer than anterior lobe, 

 black with white basal margin. Scutellum entirely black. 



Ground color of legs black voluptarius sp. nov. 



c^ Pronotum entirely black. Small species (about 3 millimeters). 

 e\ The two pronotal lobes of equal length. Radial vein of corium 

 not dilated in its basal half. Femora pitchy brown, basal half 

 of the middle and hind pair whitish testaceous. 



montanellus sp. nov. 



e'\ Posterior pronotal lobe one-half longer than anterior lobe. Radial 



vein of corium gradually callosely dilated in its basal half. All 



femora entirely black montivagus sp. nov. 



b'. Corium black with three white spots. Rostrum passing base of venter. 



vulvatus sp. nov. 



Hyginus kinbergi Stal. 



Luzon, Laguna, Los Banos and Mount Maquiling; Tayabas, 

 Malinao. Mindanao, Butuan. 



This species (with which H. semperi Stal and consputus Stal 

 must be united) is common in the Philippines and is extremely 

 variable. The upper side of the head is more or less declivous
