gives the appearance of three minute red tufts. Clypeus black with 

 white hairs. Abdomen black with an encircHng white band and a 

 central, longitudinal, rufus band which varies greatly in length and . 

 breadth, upon which are some variable white marks, which usually 

 consist of two short, obKque lines near the base, a triangle in the mid- 

 dle, and a series of chevrons near the apex. Falces dark testaceous 

 with sparse short white hairs; maxillee and labium brown; sternum 

 dark with black and white hairs; venter black with rufus hairs, 

 palpi and legs barred with black and rufus excepting the proximal 

 ends of the femoral joints which are pale. 9 . Cephalothoras 

 covered with brown, black and rufus hairs, with a grayish band 

 behind dorsal eyes, which passes downward and forward on the 

 sides to the lateral eyes; clypeus covered with white hairs. Ab- 

 domen rufus or light brown with a grayish basal band, behind which 

 is a curved black band; there are several other curved black bands 

 near the apex, and a central, longitudinal black line. Falces, 

 mouthparts and sternum brown; j^alpus pale with hair which is 

 light brown excej)ting at the extremity, where it is white; legs, first 

 pair dark; the others brown with black hairs. 



Habitat: Pennsylvania, New York, Wisconsin. 



Since describing hoyi and pinus as two species (1883) we have satisfied 



ourselves that pimts is the female of lioyi. 



HABROCESTUM (E. Simon), 1876. 



Cephalothorax rather short, one-fourth to one-third longer than wide, mod- 

 erately high to very high: thoracic part often convex, but slightly 

 dilated on the sides, which are somewhat rounded, only a third the 

 longer. CeiDhalic part a little convex, inclined, limited by a faint 

 depression. Quadrangle of ej'^es one-tliird wider than long, and equally 

 wide in front and behind, or a little wider behind. Anterior row of 

 eyes rather unequal — middle about twice lateral — middle but little 

 separated, lateral by not more than one-third their diameter, forming 

 a line straight or sliglitly curved upward. Second row small, and 

 nearly half way between the first and third rows. Dorsal eyes equal 

 to or a little larger or smaller than the anterior lateral, forming'a row 

 about as wide as the cephalothorax at that place, and almost equally 

 distant from each other and from the lateral borders. Clypeus varies 

 from one-half to two-thirds the large middle eyes. Sternum 

 one-half longer than wide, often truncated in front and contracted 

 behind, produced between the anterior coxse, which are separated by 

 a little more or less than the width of labiuni at its base. Labium 

 as wide as long ^ and less than one-half the maxillae. Falces weak 



1 This is true at least in the American species.
