length, seven iu width and four and a half millimeters in 

 height. The cephalothorax, or forward part of the body, is dark 

 grayish brown, with a lighter yellowish wedge-shaped baud in 

 the middle, extending nearly the entire length ; in old speci- 

 mens the whole he.vd portion is nearly uniform light, gray . The 

 middle pair of eyes (for there are three rows) are encircled with 

 yellow hair, the extreme front being of the same color. The ab- 

 domen in old specimens is yellowish brown, obscurely marked. 

 A median narrow dark baud, visible for nearly the first half, 

 joins a darker facing in front and gives off laterally a diagonal 

 stripe, followed with a lighter interrupted stripe in the same 

 direction ; the middle baud shades imperceptibly behind, with 

 a broad, indistinct baud covering the whole remaining upper 

 surface, becoming narrower and terminating at a point at the 

 end of the abdomen ; frequently this band shows indications 

 of being divided transversely by tive faint dark yellow thiu 

 stripes ; its lateral margins are circumscribed by lighter spaces 

 between the almost obscured stripes. Specimens just arriving 

 at maturity have the abdomen a rich, dark brown ; the nar- 

 row stripe in front on the abdomen is lighter, the broad baud 

 is wanting ; five thin, transverse yellowish gray stripes divide 

 the abdomen backwards, commencing with the most conspicu- 

 ous one a little in advance of the middle. The abdomen often 

 appears very dark at first glance, the markings upon it not being- 

 apparent. In the adult underneath the abdomen is pinkish 

 yelloAv, the sternum is light and the lip darker. The legs in- 

 crease slightly in thickness, also becoming lighter colored from 

 the fourth to the first pair ; the first legs are light gray, yel- 

 lowish toward the body, densely clothed with a few scattered 

 long dark hairs, and the hind legs are dark or yellow, with 

 black isli spines. The first and second legs have the last three 

 joints tibia, metatarsus and tarsus black beneath ; near the 

 body these legs are lighter, the femurs are yellowish olive. 

 The mandibles are covered with yellow hair on the front. 



I have recently examined a male specimen of /,//rosv/ ///W//V.r. 

 Marx, kindly sent to me by Mr. Xathan Hanks. The speci- 

 men, I am informed, has similar castle-building habits such 

 as described in ENTOMOLOGICAL XHWS, February, ls>9. The 

 type of n/V'7' .' has not been recovered in the Marx collection, 

 but Mr. Banks sent rue the above specimen, taking it to be
