3. Chthnniiis ciirindigilatiis') Sim. 



1899. E. Simon. (15.) p. 122. 

 Two pair of eyes which are "subcontigui", removed from front margin a 

 distance only half their diameter. Céphalothorax distinctly longer than broad, 

 "antice recte seclus, sed in medio leviter depressus" ; the skin is delicately coria- 

 ceous and a few short hairs are present. Antennae as usual. Tibia of the palps 

 rather long; the hand is a trifle longer, but scarcely broader than the tibia, and a 

 little shorter than the fingers, which are slightly curved. Sumatra. M. Simon 

 writes about this species, that it "deviendra sans doute, dans la suite, le type d'un 

 genre special", on account of "les doigts de sa patte-màchoire légèrement courbes, 

 ses yeux de chaque côté presque contigus et ses téguments finement coriaces, 

 garnis de soies assez courtes". On account of this possibility I have not changed 

 its name. 



Megathis Sleek. 



1875. A. Stecker (4.) p. 519. 

 If the front margin of the céphalothorax is really prolonged into a median 

 tooth, as represented in Steckers figures (taf. Ill, fig. 2 a) , the genus must be 

 regarded as natural. If this median prolongation by future students, is demon- 

 strated to be of a similar nature as the eminence in f. inst. C. W'lassicsi Dad., 

 Megathis Kochi Stk. at least must be regarded as a typical Chthonius C. K.; but M. 

 desiderata Steck, is always sure to be referred to another genus than the majority 

 of the Chthoniinae Dad. on account of the granulation of the palps and their clavale 

 hairs, under the supposition that these among the Hemictenodaclijli unitjue characters 

 are real, not chimeric 



4. Megathis Kochi Steck. 



1875. A. Stecker (4.) p. 521, taf. Ill, figs. 1—6. 

 Two gigantic eyes, well separated from the front margin. Céphalothorax is 

 distinctly longer than broad; front margin prolonged into a prominent median 

 tooth. The femurs of the palps are smooth and the hairs simple and pointed; the 

 hand is much longer and broader than the tibia. Fingers with five marginal teeth 

 Indian Region. 



5. Megathis disiderata Steck. 



1875. A. Stecker (4.) p. 522, taf. IV, figs. 1—4. 

 This species differs from the jjreceding by the clavate hairs of the abdomen 

 and palps and by the large granulations of the femora of these. India.

') This name has been used previously by Balzan for a Soutli-American species (1890 46. p. 449).
