STEARODEA.—ASAGENA. 37 
~T 
STEARODEA. 
Stearodea, F. P.-Cambridge, Ann. & Mag. Nat. Hist. (7) ix. p. 18 (1902). 
Type S. bipunctata (Linn.). Europe. 
The chief difference which separates this genus from others of the group lies in the 
great size of the anterior central eyes. The margin of the chitinous ridge on the 
anterior portion of the abdomen in the male is toothed as in the other allied genera. 
One species only occurs in the collection before me, which may readily be recognized by 
the form of the vulva. 
1. Stearodea americana, sp.n. (Tab. XXXV. figg. 12, 124, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 5 millim. 
Lab. Mexico, Omilteme in Guerrero (/7. H. Smith). 
This species resembles our European S. d/punctata in general appearance, but the 
form of the vulva is quite different. 
ASAGENA. 
Asagena, Sundevall, Consp. Arachn. p. 19 (1833). 
Type .A. phalerata (Panzer). Europe. 
The type-species of this genus can readily be distinguished from that of Lithyphantes 
by the rugulosity of the sternum and the greater comparative height of. the clypeus ; 
but I very much doubt if these characters will prove to be constant. ‘The same remark 
applies to the absence of any chitinous division between cox iv.; but for the present 
I keep the two genera separate. 
The species known to me may be recognized by the following characters :— 
Males. 
a. Embolus of palpal bulb long, conspicuous, filiform, encircling 
the face ofthe bulb. . . . . . . 1 ww. .  . alticeps, Keyserl. 
b. Embolus of palpal bulb very short. . . . . . . . . . guadrimaculata, O. P.-Cambr. 
1. Asagena alticeps. (Tab. XXXV. figg. 16, 16a, ¢.) 
Asagena alticeps, Keyserl. Spinn. Amer., Therid. ii. p. 4, t. 11. figg. 186, 136 a-e (3). 
Lithyphantes letus, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 181, t. 22. figg. 12, 
12a-f(s)*. 
Type, d; of A. alticeps, in Mus. Brit., total length 3°7 millim.; that of Z. lwetus, g, in coll. Godman & Salvin, 
total length 3°75 millim. 
Hab. Costa Rica (Sarg *).—Co.omsta '. 
Having carefully compared the types of the two forms described, I can find no real 
difference in the shape of the processes of the palpal bulb.
