(26. Micrathena reduviana. 
Acrosoma reduviana, Walck. Ins. Apt. ii. p. 201 (¢)'; Abbot, Georgian Spiders, no. 49 ( ¢ ) *

Walckenaer (loc. cit.) says that M. reduviana is “armé de huit épines,” which is 
confirmed by Abbot's figure, and it is difficult therefore to understand how McCook 
came to identify it with Jf. mitrata (Hentz). The species is included here for the 
sake of clearing up its characteristics and settling its identity. |

Type, 2, in coll. Godman & Salvin. Total length 11 millim. 
Characters as in M. sagittata, except that the femora of the legs are less granulose, the sternum is not 
markedly convex in the centre, and the patella of the legs are more decidedly dilate in the middle 
posteriorly. Abdomen elongate-oval, without anterior or lateral marginal spines or cusps, but with a 
broad deeply bifid prolongation behind, the two branches closely adjacent to each other, coniform, 
bearing a short sharp spine at their apex.

The females received of this species are, so far as I can make out, quite immature, 
and the males obviously so. If the females were adult, it is hardly likely that they 
would be of the same length as immature males of the same species. It appears to me 
to be possible that both sexes are the young of M. schreibersi. 
The following species are unknown to me :—
