a very shining appearance ; the tergites are longitudinally divided with the exception 

 of the eleventh. All the tergites are strongly granular all over, and have along the 

 posterior margin about 12 long, strongly clavate hairs in addition to two lateral ones, 

 but they have scarcely any median hairs in front of the row. The " tactile " hairs of 

 the eleventh tergite are missing in the specimens examined. 



Antennce. — The terminal hair extends in a very high degree beyond the short galea, 

 which is rather clumsy, somewhat attenuated, with three short terminal teeth. 



Palps (PL XXX. fig. 16 a ; text-fig, 67).— The maxillw are granular, most distinctly 

 laterally ; the palps are distinctly granular above with the exception of the hand ; 

 the ventral side is less distinctly granular and the fingers are 

 smooth. The hairs of the femur and the trochanter, especially 

 anteriorly, are long, strongly clavate, somewhat curved, and directed 

 forwards ; the hairs of the two following joints increase in length 

 and slenderness towards the fingers, in which the pointed hairs are 

 completely simple or provided with one or several median teeth. 

 The trochanter, which is 1-5 as long as wide, is strongly convex 

 anteriorly, but posteriorly slightly produced ventrally ; dorsally it is 

 produced into a fairly high rounded protuberance. Tue femur has 

 a fairly long and well-defined stalk, beyond which it is widened out 

 to a point somewhat behind the tip and then is a little attenuated. 

 It is 2-7 as long as wide ; the anterior outline is very slightly convex 

 and then concave, while the posterior is gradually and moderately 

 convex beyond the stalk and then with a moderate concavity or even 

 incision, distally passing into a slightly marked convexity, which is 

 again terminally followed by a concavity. The tibia, which has a 

 long and fairly well-marked stalk, is almost as long as the femur, 

 but distinctly wider and 2-2 as long as Avide ; anteriorly, beyond 

 the stalk, it is fairly distinctly convex and terminally slightly 



concave, while the posterior outline beyond the fairly pronounced ^ ^■' f '

 which is about 2-5 as long as wide, is I'S wider than the trochanter 

 is long; the hand, which is almost as long as but 1-4 wider than tibia, is almost 1-6 

 longer than both wide and deep, a trifle wider than deep, and 1'4 as long as fingers, 

 which are a little longer than hand is broad ; the lateral outlines as well as the ventral 

 are moderately convex, while the dorsal one is very distinctly convex. The fingers 

 gape a trifle when closed, and each bears anteriorly two or three accessory teeth. 

 Posteriorly each finger has about eight accessory teeth. The number of the ''s;pots" 

 and the arrangement are a little variable in the specimen, but the arrangement in the 

 main is the same as that in the figures ; anteriorly the immovable finger has a single 

 " spot " behind the basal hair, four beyond and behind the median hair, and three in
