from the Seychelles Islands and Rodrigues. 285 
base narrowly ringed with darker brown; 5 with the basal 
third yellow in the Silhouette specimens, but yellow-brown 
to light brown in most of those from Mahé. 
Head 2°6 times as long as broad ; eyes occupying 0°23 
and produced part about 0°14 the total length. Cheeks 
feebly arcuate in the basal half, genal spines few, one im-~ 
mediately behind eye and one near base somewhat stronger 
than the others and in some cases also a median pair ; 
faintly knobbed. Postocular bristles long, much longer 
than the length of the eye ; anteocular pair also long, 
brown. Eyes bulging, faintly facetted ; ocelli situated as in 
D. rex and others. Antenne about 1°6 times as long as the 
head ; joints 3 to 5 mildly claviform ; relative lengths of 
joints 3 to 8 approximately as follows :—68:60:49:37: 26:25. 
Pronotum medianly 04 the length of the head and about 
0°6 as long as broad; all setz very fully developed, yellowish- 
brown; the pair at posterior angles approximately 0°7 the 
length of the pronotum ; the inner posterior marginal pair 
longer, viz. 0°8 the length; the mid-lateral pair 0-6 and the 
pair at anterior angles 0°4 the length of the pronctum. 
Pteronotum very slightly broader than long. Wings 
faintly tinged with yellowish-brown, rather broad, reaching 
to about the seventh abdominal segment ; fore-wings about 
thirteen times as long as broad near middle and furnished 
with 27 to 388 duplicate cilia. Legs normal, fore-femur 
slightly incrassate, with a noticeable swelling at the apical 
third within and a long hair equal in length to the breadth 
of the femur near basal third within. 
Abdomen somewhat heavy, basally stouter than ptero- 
thorax, and narrowing from the third segment ; tube about 
or perhaps slightly more than 0°8 the length of the head, 
narrowing gently to distal third and thence more sharply to 
apex, where it is rather noticeably constricted and one-half, 
or less than one-half as broad as at base. Terminal hairs 
about 0°55 the length of the tube. Abdominal bristles much 
as in seychellensis, those on so. 9 nearly as long as the 
tube. 
3d .—Smaller and more slender with the tube only 0°65 to 
0-7 the length of the head. Fore-femur not strongly 
incrassate and with the swelling at distal third within 
noticeable; sickle-shaped spine stout in the only specimen 
in which it has been preserved; several sioutish spines on 
outer margin near base; segments 7 and 8 of abdomen 
practically subequal, the latter being slightly shorter upon 
measurement (12:11), and about 0°4 the length of the tube
