1902,] NEW HARVEST-SPIDERS, 407 



internal tubercular spines ; tibia and tarsus with three pairs of 

 long and strong spines. 



Legs with coxte tubercular, that of the 1st with about three 

 strong blunt spines ; coxae of 2nd and 4th pairs tubercular above ; 

 trochanter tubercularly spinous, that of the 4th with two longish 

 superior spines ; femur of 1st with three spines in its proximal 

 half below, of the 3rd with spinous tubercles posteriorly. Tai'sal 

 segments of 1st leg 5, of 2nd 13-15, of 3rd and 4th 4. 



$ . Smaller and more thickly granular ; ocular tubercle less 

 tubercular ; dorsal scute without the anterior three pairs of spines, 

 the long spines shorter than in the male and preceded by a pair 

 of low tubercular spines ; no long spines on the free tergites, but 

 the tubercles all longer and more spiniform than in the male 

 (text-fig. 82, B). Pcdpi shorter, but otherwise similar to those of 

 male. Distal protarsal segment of \st leg thickened but strongly 

 excavated below. 



Measurements in nnn. : — S • Total length of body 7 ; of palp 

 about 12; 1st leg abovit 15, of 2nd about 25, of 3ixl 27, of 

 4th 24. 



Log. Madagascar : Ambohimitombo, in the Tanala district (C /. 

 Forsyth Major, type S ) ; also Betsileo (Deans Cotoan). 



The specimens from Betsileo are three in number, an adult and 

 two subadult females, the latter diffei'ing from the former in the 

 absence of the emargination at the extremity of the protarsus of 

 the 1st leg. They are distinguished from the typical examples 

 from Ambohimitombo by the shortness of the dorsal spines and 

 tubercles, which are only about half as long as those of the female 

 of the typical form of A . rostrata. I propose therefore to regard 

 the Betsileo form as a subspecies which may be called A. o'ostrata 

 subsp. Gowani nov. 



A. rostrata certainly differs from A. armata Loman in the 

 spine-armature of the dorsal surface, the dissimilarity between 

 the sexes with regard to spine-armature, &c. 



■ It is noticeable that Loman makes no mention of the modifi- 

 cation of the distal end of the protarsus of the 1st leg in eithei- 

 of the sexes of A. armata. 



Judging, too, by the measurements given of the appendages, 

 A. armata is a much shorter- legged form than either of the 

 species hei'e described. The following are the leg-lengths in 

 millim. of A. armata: — 1st leg 7*5, 2nd 11, 3rd 8-5, 4th 12. 



AcuMONTiA MAJORi, sp. n. (Text-fig. 83, A, p. 408.) 



S ? Coloiijr more ruddy brown than the foregoing. 



Dorsal sciote sparsely granular ; ocular tubercle as high as in 

 A . rostrata, but thicker at the base and less tubercular than in 

 the male of that species ; a pair of small spines on each side 

 of the carapace near its fore border, in addition to the three 

 projecting between and outside the mandibles ; posterior area 

 less elevated than in A. rostrata, and armed with two pairs of 

 spines, the posterior long, the anterior short, directed obliquely
