as that, slightly arched behind. Frontal stripe deep orange yellow or 

 .sometimes very slightly tinged with brownish, and somewhat paler at 

 the lower fourth or less, broad (not comparatively rather narrow) 

 parallel-sided but sometimes very slightly contracting below, covered 

 with dense short depressed pale brownish yellow or rich orange yellow 

 pubescence which grows sparse on the lower part at where it becomes 

 paler ; frontal callus blackish castaneous, slightly raised with a fine 

 inconspicuous median sulcus throughout, elongate triangular with the 

 lower margin nearly straight and with the tip sharply pointed but not 

 well prolonged above as Loew described, about twice as long as its 

 broadest lower margin, quite separated from the eye-margins by rather 

 narrow intervals ; vertex somewhat paler but obscured by short erect 

 blackish or brownish pubescence which at the lateral parts is intermixed 

 with some yellowish depressed hairs extended up from the forms, 

 behind that is a short brownish black fringe but not conspicuous nor 

 overlapping ; frontal triangle moderately raised, deep orange yellow or 

 pale brownish yellow, on the upper margin with a narrow brown or

 which is quite interrupted in the middle third or less or sometimes 

 more, and which does not usually touch to the frontal callus. Face 

 strongly convex, deep orange yellow and usually with a slight brownish 

 tinge especially about the mouth-edge and near the eye-margins ; epistoma 

 much broader than deep, almost bare but about the upper lateral corners 

 bearing numerous short erect light brownish yellow pubescence, the 

 lateral pits rather small and shallow ; cheeks narrow, about one-thirds 

 as wide as the epistoma and nearly equal width throughout, covered 

 with numerous rather dense short fine pale brownish yellow pubescence 

 which is rather inconspicuous and does not apparently grow longer 

 below but on the jowls it is rapidly lengthened and well conspicuous, 

 this long pubescence on the jowls somewhat extending up to the back 

 of the head which is shallow at the lower part and is hollowed out 

 above ; back of the head yellowish grey, furnished with numerous
