by Redtenbacher to separate his closely related Philippine S. punc- 

 tipes, are not valid. In the present material the spines of the 

 caudal femora are blackish brown, tinged at their bases with the 

 same color, while the dorso-internal margins of the median tibiae 

 are armed with from two to four spines, sometimes in the same 

 specimen. The ovipositor is straight, not weakly curved, but this 

 again does not appear to constitute a safe specific character in the 

 genus. 



We recognize punctipes as valid due to the female subgenital 

 plate, described as "triangularis, elongata, acuminata, apice 

 incisa, lobis angustis acuminatis." In the females here recorded 

 this plate is short, the lateral margins strongly convergent and 

 rounding into the apex, which is weakly rotundato -trigonal emar- 

 ginate, in this respect agreeing more closely with S. unicolor 

 Redtenbacher, from Pelew Island. 



The heavy blackish brown suffusion on the dorsal half of the 

 internal face of the caudal femora proximad is a striking feature 

 in the material at hand. Ventral femoral margins showing the 

 following range of spines in the series. Cephalic internal to 1, 

 cephalic external 0, median internal 0, median external 0, caudal 

 internal 7 to 9, caudal external 8 to 14.

Segestes frater new species. Plate XVI, figure 2. 



This insect shows a most remarkable general resemblance to 

 Segestidea soror, here described from the same locality. That 

 species is particularly distinguished by the more evidently rugulose 

 pronotum with shallower lateral lobes, tegmina which are slightly 

 broader distad and there run to a point at the sutural margin, 

 heavier and fewer dark spots on the tegmina, dark internal suffusion 

 of the caudal femora and presence of a small spine disto-dorsad 

 on the external surface of the cephalic tibiae. These differences 

 would appear to make confusion impossible, but, were the specimens 

 not carefully examined, their general resemblance is so decided 

 that one might easily fail to recognize the presence of two species. 



The present insect is nearest the decidedly smaller S. unicolor 

 Redtenbacher, described from Pelew Island. It differs further in
