316 ME. C. J. WITH ON SOUTH-AMEEICAN CHBLIFERIN^ 



Material. — Of this species I have examined two specimens ( J ), the one found 

 beneath the elytra of a specimen of Acrocrinus longimanus from Brazil and the other 

 from Tobasis Kapa (Keyserling Coll.), both found in company with specimens of 

 Ch. macrochelatus Tom. EUingsen's specimen is from Brazil, found under exactly 

 the same circumstances as the former of the above-mentioned ; all other localities may, 

 as shown by Ellingsen {cf. i8. p. 5), be regarded as doubtful. 



Hemarks. — Well-developed specimens ( c? ) of this species can scarcely be confounded 

 with any other form of Chelonethi on account of its powerful palps, with the peculiar 

 shape of the dorsal tubercle of the trochanter and tibia, the long and slender stalks of 

 femur and tibia, as well as by its exceedingly deep hand with the gaping fingers ; but 

 perhaps smaller animals are less easily distinguished from very large specimens of 

 Ch. macrochelatus Tom., for instance that of which Balzan has given the measurements 

 (ii. p. 513) — perhaps Balzan has, like Daday {cf. 8. p. 173, and Ellingsen, 15. p. 154), 

 confounded the two species. As regards the relation of the South-American species to 

 Tomosvary's typical form from Dalmatia, I refer to EUingsen's discussion (18. pp. 5-6).

Male. 



Ce])halothovax. — Large ocular spots rather indistinct. The cephalothorax, which is 

 distinctly longer than broad, has two broad transverse stripes, of which the more 

 prominent anterior one is curved backwards in the middle, while the posterior almost 

 straight stripe is rather indistinct ; in the middle in front of the anterior stripe a 

 rather shallow longitudinal depression is observed. The integument of the head 

 appears polished and is very minutely granular, but is behind the median transverse 

 stripe smooth or almost so ; the hairs are rather short. 



Aldomen. — The fairly long and slender abdomen has all the tergites with the 

 exception of the eleventh longitudinally divided, the first three are wider, but distinctly 

 shorter than the following. The sclerites are almost smooth and the tergites bear 

 along the hindmost margin from 14 to 20 moderately long {%) hairs, and the median 

 tergites possess in addition to these two lateral and a single median hair in front of 

 the row on each side ; " tactile " hairs missing in examined specimen. The ventral 

 surface behind the genital area was distinctly keeled, the two sclerites of each sternite 

 making an acute angle with each other. 



Antennce (PI. XXXI. fig. 34 a). — The galea, which extends distinctly beyond the 

 terminal hair, is provided with a large number of branches as seen in figure. 



Palps (PI. XXXI. fig. 34 b ; text-fig. 82). — The palps are almost smooth except
