moderately arched. Frontal stripe greyish yellow, but with a blackish 

 sheen on the vertex, moderately contracting from . the vertex to the 

 lYontal eye-ang'es and about four times as long as its broadest part or 

 about eight times as long as its' narrowest part ; pubescence on the 

 frontal stripe deep golden yellow, dense, partly depressed, and partly 

 sloping; lower frontal callus somewhat quadrate long, not touching the 

 eyfes, moderately elevated, dark brown to brownish black, shining ; 

 upper frontal callus very narrow and long, very slightly raised, almost 

 always quite separated from the lower callus but in denuded specimens 

 sometimes connected with the latter by a fine line, black and shining ; 

 frontal triangle shining dull yellow, but almost always with very narrow 

 lateral margins dusted with yellow, and with pale yellow dusted double 

 crescent just above the antennal pits, in the middle there is a fine but 

 distinct longitudinal furrow from the lower frontal callus to the fine 

 edge between the antennal pits ; vertex with no ocelligerous tubercle, 

 bearing numerous pubescence which is quite similar to that on the 

 frons but a little longer. Face broad, with slightly puffed out cheeks 

 a.nd with somewhat prominent yellow epistoma, which is subquadrate 

 anil contracts at the middle where the lateral pits exist, and which 

 bear distinct yellow pubescence ; cheeks yellow but slightly paler and 

 about half as wide as the epistoma, bearing rather short and not very 

 abundant yellow pubescence which becomes longer and denser about 

 the jowls ; all along below the eyes and up all the back of the head 

 to the vertex is a comparatively wide dull yellow bare rim, behind 

 which is a rather short though rather crowded ciliation of yellow or 

 yellowish brown hairs which extend on the occiput and which become 

 slightly longer below to the jowls ; back of the head distinctly hollow- 

 ed out, all oale yellow (sometimes ashy grey in paler specimens), 

 and bearing some scattered long pale hairs. Proboscis deep reddish 

 yellow, shorter than the depth of the head, rather stout, with very 

 long yellow hairs behind the stalk, and with slightly shorter but 

 stouter yellowish brown hairs below the brownish black sticker-flaps
