454 MR. H. E. HOGG ON SPIDEBS 



Group Tetragnathese. 



Genus Tetragnatha Latr. 

 Tetragnatha rubeiventeis. 



Tetragnatha rubrivenlris Dolescliall, Nat. Tijd. v. Nederl. Ind. vol. xiii. 1857, p. 40. 



One male. 



M. Simon, Hist. Nat. des Ar. vol. i. 1892, p. 718, gives drawings of the mandibles, 

 lip and maxillse, and male palp of T. ruhriventris DoL, which agree exactly with the 

 same parts of this specimen, 



Doleschall's description {loc. cit.) agrees well enough with this, except that he 

 calls the underside of the abdomen "purple-coloured" and gives the length as 4 mm. 

 only, while in this one it is 9 mm. and the abdomen is dark grey underneath. 

 Thorell {loc. cit.) makes the length of his specimen 14| mm. and says the abdomen 

 is golden-red, which this male is on the upperside. 



Prof. Kulczynski records T. rubrimntris Dol., and then describes T. plKBodactyla 

 Avith a drawing of the mandible which seems the same, and his coloration is the same 

 as this, with the exception of yellow spots on the abdomen and a dark ring on the 

 tarsi and metatarsi i. and ii., the length being 7 "47 mm. If not the same, the two 

 species would seem to be merely varieties. 



Tetragnatha ? leptognatha. 



Tetragnatha leptognatha Thorell, Ragni di Selebes, 1877, p. 101. 



One female. 



Both in coloration and proportions this example seems to agree with Thorell's 

 description of the above-named species, but his specimens are slightly larger. The 

 mandibular teeth and shape of fang are the same, and I have not much doubt but that 

 it must be ascribed to Thorell's species. 



I make the measurements (in millimetres) as follows : —
