and find that the present form cannot possibly be associated 

 with it. Ipo presents a structure of head, clypeus, and lorse 

 very distinct from anything I have yet seen in the Philippine 

 fauna. The tegmina of Ipo are quite unique in the Idiocerini, 

 very short and broad, with supernumerary cells outlined in the 

 apical portion of costal area, with the appendix short and 

 broadly extended on to the clavus, and with the claval suture 

 callously thickened toward the apex. The vertex of Ipo con- 

 ferta is very remarkable, the length at eyes being twice that 

 at middle. Neither have I seen any idiocerine insect in the 

 Philippine fauna so large and with a head and pronotum pro- 

 portionately so broad — ^the width of the head being 3 millimeters.

In some respects Ipocerus strongly resembles Chunra as de- 

 scribed and figure by Distant, but is very distinct in some char- 

 acters of first importance.

Length, 4.4 mm. ; width of head, 1.8 mm. Straw-colored ; head, 

 pronotum, scutellum, and tibiae very finely reticulately mottled 

 with brownish. Scutellum with darker clouds at lateral angles, 

 at basal middle, at apex, and three at area of transverse impres- 

 sion. The tegmina are semitransparent, tinted with pale golden 

 brown; the veins are dark brown, and except the apical cross 

 veins, with numerous short white interruptions of varying 

 lengths; the costal vein with four large, rectangular white in-
