PSYCHE. 



[March 1894. 



pale, sutures margined with brown ; coxae 

 pale, with brownish bristles, palpi grayish 

 with the tips of the second and third joints 

 brownish; legs brownish, the trochanters 

 pale, base and a ring near tip of femora, tips 

 of the patellae and tibiae whitish, also a few 

 white spots on the tarsi and metatarsi. The 

 basal joint of the mandibles of the male is 

 much prolonged above, the tip curving for- 

 ward and bearing short black hairs. The 

 eye tubercle is more prominent than in 

 P. cavicoleus. The basal segment of the 

 abdomen bears a row of spines, the median 

 pair being much the largest; the next four 

 segments have each a pair of humps crowned 

 with stiff hairs. Third joint of palpi about 

 equal to the fourth, the last joint more 

 swollen than in P. cavicoleus. The palpi, 

 as a whole, shorter than in that species.

Phlegmacera cavicoleus Pack. [Sabacon 

 spi?iosns Weed, Amer. nat. June, 1893). 



Described from Bat Cave, Kentucky (Pack- 

 ard) and New Hampshire (Weed). I have 

 collected at Ithaca, N. Y., under rotten logs 

 in a deep gorge, what I take to be the same 

 species. The female agrees with Packard's 

 description and figure ; the male has the 

 fourth joint of the palpi less enlarged than in 

 the female, the basal joint of the mandibles 

 is prolonged upward in a horn, and there 

 are stiff bristles on the abdominal ridges. 



Nemastojna crassipalpis Koch ( Ara- 

 chniden aus Sibirien und Novaja 

 Semlja) belongs to this genus. 



Of Nemastoma there are three species. 



Fourth joint of palpi less than twice as 

 long as the fifth. . . . N. innps. 



Fourtli joint of palpi twice as long as the 

 fifth. 



Dorsum with some spines. N. modesta. 

 Dorsum without spines. N. troglodytes. 



Nemastoma inops Pack. Bat Cave, Ken- 

 tucky. 



Nemastoma troglodytes Pack. Clinton's 

 Cave, Utah. 



Nemastoma jfiodesta n. sp. Length, 1.2 

 mm. ; gravid female, 2 mm. The color of the 

 dorsum is dark red-brown ; the femora, 

 patellae, and tibiae of the legs brownish, the 

 other parts of appendages yellowish. The 

 dorsum is granulated; the eye tubercle quite 

 wide, and the eyes look upward; from each 

 side of the hind margin of the eye tubercle 

 there extends toward the posterior angles of 

 the dorsal shield a curved row of peculiar 

 tubercles, which have their summits enlarged, 

 lengthened and flattened ; at about the region 

 where the cephalothorax and abdomen are 

 united there is a curved transverse row of 

 these tubercles, connecting the two longi- 

 tudinal rows; this connecting row has, 

 behind, two short branch rows of a few tuber- 

 cles; behind these short rows are two diverg- 

 ing rows of four curved spines. The 

 abdominal segments behind the dorsal shield 

 are usually crowded together, but in the 

 gravid female they are widely separated with 

 a snow'-white connecting membrane. The 

 hard parts of the venter are red-brown, the 

 stigmata black, all granulated and furnished 

 with bristles. The trochanters are yellow, 

 somewhat globular and with bristles; the 

 other joints of the legs have fine hairs and a 

 few bristles. The femora are small at base, 

 gradually enlarging toward the tip ; patellae 

 same; tibiae more equal, the metatarsi with 

 parallel sides. Second pair of legs longest. 

 First joint of the palpi is small at base and 

 larger near the tip, the second much longer, 

 the third a little longer than the second, the 

 fourth a little shorter than the third, the 

 fifth about one-third the length of the fourth ; 

 all with bristles, most numerous on joints 

 four and five. 



California and Washington State (Trevor 

 Kincaid). Evidently not uncommon.
