Genera of the Family Attidm. 301 



Spinnerets as usual, superior longer and more slender than the inferior ; 



with two joints, which are sub-cylindrical, about as long as wide. 

 Type : H. thoracica . 



This genus, says Thorell, agrees with Philaeus in the distance between 

 the middle and lateral eyes of the first row, but differs from it especially 

 in the form of the cephalothoi'ax; in the latter respect it approaches Bellus 

 (C. L. Koch) and Homalattus (WJiite), but differs from them since the 

 quadrangle of the eyes only occupies f, not -h, the length of the cepha- 

 lothorax.

Cejyhalothraax hut slightly elevated; thoracic p rt ve y strongly dilated 

 and rounded, at least a third the longer; cephalic part plane and in- 

 clined, not limited behind; a very short and fine longitudinal stria 

 between the dorsal eyes. 



Eyes of the face very unequal, forming a line slightly curved; the median 

 eyes not touching; the lateral eyes separated by an interval almost 

 as wide as their diameter. Dorsil eyes scarcely !■ mailer than the 

 lateral, much further apart, since the slides of the head diverge be- 

 hind; these eyes p ojecdng widely above; quairangl^ at least a 

 third wider than long; d /rsal eyes further from one another than 

 from th 3 literal borders. Clypeus about half the diameter of the mid- 

 dle eyes. 



Sternum elongate (5, contracted in frjnt; anterior thighs separated by the 

 width of the lip; the two anterior pairs (particularly the first), the 

 thickest; the fourth a lit le longer than the third. 



Legs ( 3 ) 1, 3, 4, 2; (?) 4, 3, 1, 2; first pair thfe most robust; femur com- 

 pressed and claviform; tibia and patella very thick and cylindrical, 

 male as long, female shorter than the cephaloihorax, male tibia a lit- 

 tle longer, female tibia and patella equal. Tibia and patella of the third 

 at least as 1 ing as patella and tibia of the fourth (only by thf greater 

 length of the patella). Tarsus a id metatarsus of the fourth a little 

 shorter than the tibia and patella. Tibia of the fourth cylindrical 

 and parallel. Short, robust, conical tibial and metatarsal spines 

 on the two first j airs, forming inferior rows; spines equally short, 

 more slender, and not serial on the posterior parts; meta'arsus of 

 the fourth provid-d with spines throughout the length.
