ing a little ovate, extend around the margin of the eyes, while 

 straight across the head is a waving, uncertain line of the 

 golden scales. Caudad to this are black curved and a few 

 black forked scales. The occiput is often quite naked and 

 shows the black integument. All the curved scales are very 

 closely appressed, so as to seem unusually straight, and there 

 is a tendency to bright golden reflection in some of the dark 

 curved scales, so that under the compound microscope the 

 bright golden line extends indefinitely, sometimes even to the 

 vertex, leaving two sub-median dark oval spots, but under the 

 hand lens there is merely an uncertain wavy line across the 

 head. There are some black bristles around the eyes. The 

 antennae are brown, verticels and pubescence brown, the inter- 

 nodes with unusually long hairs, sometimes nearly as long as 

 the verticels ; proboscis black, swollen on the apical third, 

 which has many short hairs, labellse a little lighter, also hairy ; 

 palpi short, about one-sixth the length of the proboscis, and 

 with many short hairs near and at the apex; clypeus black, 

 median portion nude, apical and lateral portions with fine white 

 pruinosity approaching a tomentum; eyes black. 



Thorax : prothoracic lobes brown, well separated, sparsely 

 covered with black bristles. Mesonotum shows a dark brown 

 integument with a slightly paler broad median stripe, covered 

 with small narrow, almost hair-like brown curved scales and 

 heavy black bristles on the margin, at the wing-joints, and on 

 either side of the ante-scutellar space; scutellum brown, mark- 

 edly trilobed, covered with small slender brown curved scales 

 like those on the mesonotum, black bristles on each lobe ; 

 metanotum dark brown, nude, shining; pleura light greenish 

 brown with a few brown bristles. 



Abdomen truncate and hairy at the apex, entirely dark 

 brown scaled and except for very small dirty white basal lat- 

 eral spots on the third, fourth, fifth and sixth segments, that 

 on the fifth segment being the largest, but all are very small. 

 Venter mostly dark-scaled, but some specimens show tiny 

 white basal spots on a few of the segments. In considering 

 the marking, it is to be remembered that the specimens are
