Saitis minusculus, sp. nov. 
Length, 9 2.3 mm., g 2 mm. Cephalothorax reddish brown, blackish in eye- 
region ; mandibles whitish ; legs pale, prominently banded with black, except the an¬ 
terior femora in the 9 which have a dark stripe each side, and the femora and an¬ 
terior tibiae of the g which are wholly dark; sternum brown; abdomen in the g 
black, above and below, in the 9 gray, with two rows of small, indistinct pale spots 
above; venter whitish with three parallel dark stripes; body mostly clothed with 
fine white hair; $ palpi snow white. Eye-region plainly less than thoracic region, 
broader in front than behind; legs short, third pair about as long as fourth; hind 
metatarsi spined at middle and tip; anterior coxae separated by more than width of 
labium. The epigynum shows two large, connate circular spots; the $ palpus has 
apparently no projection or a very small one, to the tibia, the bulb is large, trans¬ 
versely divided, part of the basal half dark colored, a short straight style at the end 
of the upper half. 
One <£, one $ , and one young $, under leaves, Sea Cliff, N. Y.,

pus of the $. 
A NEW SPECIES OF GOMPHUS. 
By Nathan Banks. 
Perhaps the first thing to do in describing a species of Gomphus as 
new is to apologize for doing so. Specimens of this species have been 
sent to me several times during the past few years, and I have been un¬ 
able to fit it to any of the numerous species. To several of them it is 
closely allied, yet appears to differ from them more than some of them 
differ from each other. 
The species of the genus Gomphus , as restricted, can be arranged 
in several groups. One, the one in which this new species would fall, 
may be characterized as follows : apex of $ abdomen not dilated, tenth 
segment black above; no spines on the vertex of the 9. In this sec¬ 
tion would fall G. parvulus , fluvialis , amnicola , lividus , albistylus , 
nczvius and brevis. The new species, which is from Ithaca, N. Y., is 
readily separated from G. parvulus by several characters, such as larger 
size, wholly pale front, the markings on thorax, etc. In G. fluvialis 
the ninth segment of the $ is nearly four times as long as the tenth; 
in the Ithaca species it is about twice as long ; G. fluvialis also differs 
in the shape of the front, in various markings, and in shape of the $ 
appendages. G. amnicola is compared to G. fluvialis. The append¬ 
ages are stated to be the same; no mention is made of a difference in 
the length of the tepth segment from that species; a longitudinal ridge
