Latrodectus hasseltii Thor., 1870. 



Kongl. Svenska Akad. Forhandl, 1870, no. 4, p. 369. L. Koch, 

 Arach. Austr. 1871, p. 276. Hah. New Holland ; Rockhampton ; 

 Bowen (Port Denison). — This species is undoubtedly identical 

 with scelio Thor. 



Latrodectus hispidus (C. Koch), 1836. 



Die Arachniden, iii. p. 9, fig. 166. ^wh Meta. Hah. Greece. — 

 Probably identical with L. tredecvm-guttattbs (Rossi). • 



Latrodectus hystrix E. Simon, 1889. 



Ann. Soc. Ent. Fr. (6) x. p. 99 (1889). Hah. Yemen {Simon) ; 

 Aden {Yerhury). — A very distinct species, recognizable by its 

 straight posterior row of eyes, and abdomen clothed with short, 

 stiff bristles. 



Latrodectus indicus E. Simon, 1897. 



Mem. Soc. Zool. Fr. x. p. 252 (1897). (scelio, var. hidica.) 

 Hah. North Guzerath.— Bull. Mus. d'Hist. Nat. no. 7, p. 289 

 (1897). Hah. Mascat, Kurrachee. — Pocock, Arach. Ind. p. 23, 

 fig. 80 (1900). This is a variety of L. hasseltii = scelio Thor. 



Latrodectus intersector "Walck., 1837. 



Insectes Apteres, i. p. 649. Hah. America. — Undoubtedly a 

 varietj^ of L. m,actans Fabr. 



Latrodectus katipo Powell, 1870. 



Trans. New Zealand Institute, iii. p. 57. Hah. New Zealand. — 

 The relatively shorter legs of the first pair, and the straightness 

 of the posterior row of eyes, in the female (I have not seen the 

 male), would suggest at first that this is a distinct species and not 

 identical with hasseltii Thor. = scelio Thor., but I find that this 

 character is not by any means constant. The hairy clothing on 

 the abdomen furnishes, however, a very good distinctive chai-acter.

 ■the United States,' ed. Burgess, p. 153, pi. 17. fig. 3. Sub Theri-
