tarsal digitules rather stout, knobbed ; digitules of claw longer than the 

 claw and knobbed. Hairs on legs rather small and scanty. 



Anal lobes rather prominent, bearing a large seta 75 ji. long, and a 

 number of quite stout conical spines and spinnerets. Anal ring normal. 

 Female ovisac unknown. 



Eggs and larvne unknown. Male unknown; male sac white, elongate, 

 about 2 mm. long and 75 ram. wide. 



Habitat. — On a creeping vine. Collected by H. Caracciolo, Port of 

 Spain, Trinidad, W. I.; Jan. 27, 1894. 



Rem. — This is No. 6160 of the U. S. D. A. collection. The most 

 marked characteristic of this species is the peculiar arrangement of the 

 secretion described above. It seems to resemble R. filicico/a, Newst. 



A NEW SPECIES OF SINEA. 



BY A. N. CAUDELL, DEPT. OF AGRICULTURE, WASHINGTON, D. C. 



Si7tea complexa, n. sp. — Length, (^ , 8 to 9.5 mm., $, 9.5 to 11 

 m.m; width, ^, 3 mm., 9- 3-5 to 4.5 mm. General colour ranging 

 from a very dark brown to pale cinnamon. Head armed with three 

 pairs of anteocular spines, the posterior pair the longest, with smaller 

 ones interspersed. Behind the eyes, with several sharp spines, one near 

 each ocellus being almost as long as those of the posterior anteocular 

 pair. Neck spinose. Antennae som.ewhat pallid, with a slight rufous 

 cast at the distal ends of the segments. 



The anterior femora are m.uch swollen and armed with the usual 

 long, sharp, dorsal spine, and with ten spines beneath arranged in two 

 longitudinal rows. The last two spines of the inner row are much larger 

 and longer than the others, and the terminal one is out of alignment, so 

 that it is rather on the dorso-lateral surface. {Sanguisuga and some other 

 species also show this arrangement of spines on the anterior femora, but 

 in these cases there is no striking enlargement of the spines, and hence it 

 is not so noticeable. The nymphs of diadema, and probably other 

 species as well, have dorso-lateral spines on the anterior femora.) This 

 spine is almost as long as the dorsal one and, when the femora is viewed 

 from the front, is quite prominent. In this view the second spine also is 

 somewhat prominent. The anterior tibias have the usual double row of 

 three strong spines below. They are pale towards the tip, with the apex 

 black. The dorsal and two enlarged ventral spines of the rmt°rior
