occasionally they are found at tbe bottom of the tree. Though /J^yj 

 is a strong flyer, it does not appear to often go far from its birthplace. 

 The more lethargic female keeps the males near home. From its habit 

 of assembling, where one moth is found others are generally near the 

 spot. Sometimes I have taken four or five specimens from one small 

 tree, or eight or ten on a group of young trees close together. The 

 moths do not all emerge at one time. The first was taken this year 

 on May 12th ; I found three to-day, July Gth, and they were to be had 

 by searching any day between those dates, most plentifully the first 

 week in June. Where a moth is taken to-day. if no others are then 

 to be found, search the spot again to-morrow, and often three or four 

 others will be there. I have several times found a beautiful freshly- 

 emerged specimen on the same tree I had found one on about a month 

 before. "With the search confined mostly to the young trees, the 

 concentration of the broods, the assembling habits, the succession of 

 emergences, and the partial second brood in October, this species 

 should not be hard to obtain.

PLATE III. 

 PROSOPOPHORA, n. g. 



$ adult. Scale wholly waxen, base closed ; surface with granulose raised lines ; 

 no anal cleft or tubercles, anal orifice close to the margin ; margin entire, no fringe. 

 Antennae of eight joints. Mentum monomerous. Legs atrophied. Anal ring with 

 ten hairs. Last segment of the body deeply emarginate, with its lateral lobes not, 

 or scarcely, extending beyond the line of the circumference. 



(? adult. Scale of the same material and pattern as the ^ ; antennte of ten 

 joints. 



PrOSOPOPHORA DENDROBir, 11. Sp. 



$ adult. Scale (fig. 1) hard, dull, ashy-brown, broad-oval, slightly convex, disc 

 with a large ring parallel to the margin, composed of large, connected granules, the 

 space enclosed intersected lengthwise by a median carina, which extends fi'om the 

 anterior margin of the scale to the anal orifice, and is crossed by several (5 — 6) 

 raised granulose lines, of which the posterior are often indistinct or obsolete ; the 

 wide area between the ring and the margin also crossed by similai*, equidistant, 

 straight lines (8 — 9 on each side of the scale). All the raised portions are whitish, 

 and overlay pores through which the granulose matter was doubtless excreted in a 

 spumous state ; the edges of the oval anal orifice are also whitish. The waxen plate 

 closing the base of the scale yellowish, very thin and delicate, is attached to the
