OF WASHINGTON. 191 



abdomen whitish or grayish, sometimes with a basal spear-shaped mark. 

 Posterior eye-row procurved and longer than the anterior row, which is 

 straight; A. M. E. about as large as A. S. E. Legs 4, 1,2,3; tibia IV no 

 longer than tibia I, but the metatarsus IV much longer than that of leg I ; 

 spined most numerously toward the tips. Ventral furrow three times as 

 far from spinnerets as from the epigynum ; the latter shows a large 

 rounded depression, broader than long, open and with divaricate edges 

 behind, a little median cavity near the front part of depression. 



Several specimens from Shreveport, La., and Brazos County, 

 Texas. Readily distinguished from A. fallens Htz. by the 

 absence of markings. 



Gayenna parvula, n. sp. 



Length 9 5 mm. Cephalothorax yellowish, darker on the head; man 

 dibles and lip dark brown or black ; sternum yellowish ; legs pale, un 

 spotted ; abdomen brownish or dark grayish, in one specimen with a few 

 indistinct spots. Head quite broad, low ; mandibles prominent ; A. M. E. 

 smaller than A. S. E.; P.M. E. about twice their diameter apart; sternum 

 once and a third longer than broad, truncate in front, broadest at second 

 coxre; legs moderately short, 4, i, 2,3; abdomen about twice as long as 

 broad ; ventral furrow nearer to the spinnerets than to the epigynum ; the 

 latter shows an area broader than long, trilobate behind, the side lobes 

 pointed, the middle one larger and round, and from under each end of 

 which there projects a dark line or ridge backward and outward. 



Four examples from Shreveport, La., Kissimmee, Fla., and 

 Washington, D. C. 



Theridium australis, n. sp. 



Length 9 2.6 mm., femur I 1.6 mm. Both dark and light specimens 

 occur, dark ones with a reddish, light ones with a yellow cephalothorax, 

 in both the head has a very distinct black spot extending down on the 

 clypeus and usually a little pointed behind, the legs are yellowish without 

 bands; the sternum reddish or yellowish; the abdomen gray with the 

 serrated light stripe bordered with blackish which at each end is expanded 

 into a large spot. Sometimes the stripe is nearly absent, but the large 

 black spots, two above the spinnerets and one each side near base, remain 

 very distinct. The cephalothorax is quite broad, much narrowed in front; 

 the abdomen is sub-globose, and much more hairy than in the related 

 species ; the epigynum shows as a nearly straight transverse ridge, each 

 end recurved in a small circle, in front are two long, rather slender, 

 slightly curved dark marks. 



Several specimens from Shreveport, La.
