254 ME. C. J. WITH OX SOUTH-AMERICAN CHELTFEEIN^ 



curved backwards in the middle, are present ; the second tergite is longitudinally 

 divided similarly to the abdominal ones. The cephalothorax is distinctly granular all 

 over, or, more correctly, is covered with a mosaic of small rounded plates at least on 

 the head and first tergite. A large number (about 100) very short, distinctly clavate 

 hairs are found, of which four somewhat longer are placed along the front margin and 

 about 20 along the hinder margin of the cephalothorax. 



Aldomen. — The abdomen is broad and flattened and has all the tergites longi- 

 tudinally divided ; the sclerites are minutely granular^ and bear a very large number 

 of rather short distinctly clavate hairs along the hindmost margin, viz. about 20 in the 

 first segments, 30 in the median, and 24 in the tenth ; in addition to these the median 

 and posterior segments possess two lateral hairs in front of the row and three more median 

 hairs in each half, the number varying somewhat, as it is not always easy to realise the 

 position of a hair. No " tactile " hairs seem to be present on the eleventh segment. 

 The genital area is not very conspicuous ; the anterior plate is granular, with a 

 number of hairs, of almost equal length to those of the posterior plate, with many hairs 

 in front. 



Antennae. — The terminal hair extends very much beyond the short and clumsy 

 attenuated galea, which shows traces of a few terminal teeth [cf. Balzan, lo. fig. 9 c). 

 1\xe Jiagellu7n in the examined specimen consisted of only two long hairs, of which 

 the anterior was marginally serrated, but it was probably imperfect. 



Palps [cf. PI. XXX. figs. 10 a-b, d-e). — The maxillce, which, as shown in the figure, 

 are almost triangular, are almost smooth. The palps show a mosaic of small plates 

 similar to the cephalothorax, which is, however, rather indistinct beneath and on the 

 hand and is completely wanting in the fingers. Numerous very short hairs are found, 

 which vary in form from distinctly clavate on the trochanter to very slightly clavate on 

 the hand. The trochanter, which has a very short, well-defined stalk, is 1'3 as long as 

 wide ; its anterior outline beyond the stalk is almost circular, while ventrally the 

 posterior surface is produced into a short somewhat conical protuberance, and the 

 dorsal into a larger more rounded one, giving a bigibbose appearance. 'YiiQ femur has 

 a short, very well-defined stalk, beyond which it is suddenly widened out and then 

 distinctly attenuated towards the end. It is basally much wider than the trochanter 

 and terminally only slightly so, and is 1*9 as long as wide ; the anterior outline just 

 beyond the stalk is suddenly produced into a somewhat triangular process, which 

 merges gradually into the almost straight more distal portion ; the posterior surface 

 beyond the stalk is very distinctly and almost perpendicularly raised, then almost 

 straight, and at last slightly convex. The tibia, which has a rather short, but 

 exceedingly well-marked stalk, is scarcely longer, but distinctly wider than the femur, 

 and is 1-8 as long as broad ; the anterior outline is first, just beyond the stalk, 

 strongly convex and then distally almost straight ; posteriorly, beyond the basal 

 elevation, which is scarcely marked off' distally but basally is separated by a deep
