SPILEEOPHTHALMA. 359 



covered with fulvous pubescence. The legs are ferruginous, the knees and tarsi 

 darker ; the tibial spines and the calcaria are black. 



This species bears a general resemblance to S. arachnoides, but it is larger ; the 

 colour of the pubescence all over the body is fulvous (not white) ; the second 

 abdominal segment is ferruginous, and while the form of the black mark is the same, 

 it has also on either side two fulvous marks ; and the legs are reddish, not black.

 Sphaerophthalma arachnoides, Blake, op. cit. xiii. p. 236, fig. 3 



Hab. Mexico 1 2 3 , Cordova (Edge), San Bias in Jalisco (Schumann), Venta de 

 Zopilote and Eincon in Guerrero (H. H. Smith). 



The pubescence is described by Smith and Blake as ochraceous, and that is the case 

 with most of the examples I have seen ; but in the two specimens from Venta de 

 Zopilote the pubescence is white, without a trace of ochraceous, and these examples 

 further appear to have the thorax more narrowed towards the apex. The antennae 

 may have the flagellum brownish beneath. In size the species varies considerably.

 Sphaerophthalma sumichrasti, Blake, op. cit. xiii. p. 222, fig. 3 



Hab. Mexico 2 3 (Sumichrast x ), Ventanas in Darango 2000 feet (Forrer), Dos Arroyos 

 in Guerrero 1000 feet (H. H. Smith), Oaxaca (Edge). 



This species varies in size from 12-14 millim. The black mark on the second 

 abdominal segment as figured by Blake differs from that of any specimen I have seen, 

 as well as from Saussure's figure. The latter, too, figures the second black mark as 

 incised at the base ; but in all our examples it is transverse at the base. The third 

 antennal joint is at least twice the length of the fourth.

This species may be easily known by the entire body being covered with very long moss- 

 like hair, which completely hides the colour (except in parts where it is reddish) and
