Pupn-cdxi'. — Size, about 0.88 mm. by 0.0 mm.; moasured within the 

 marginal rim. the dorsum is o.T mm. b^'O.-t*} mm. : the outside measure- 

 ment are variable and not exact, as the ani>-l(» ut which the rim bends 

 varies continually; shape of dorsum oval, prolonged caudad until it is 

 lobe-like at end, dorsal and ventral secretion wanting; lateral fringe, 

 flat upon the leaf, made up of transparent wax rods, coalesced nearl}" 

 to the distal ends and about the width of case. Dorsum with a sharp 

 keel extending its entire length; within the ridge formed })y marginal 

 rim there is a sunken line extending around case; al)dominal segments 

 conspicuously set off to this sunken space; cephalo-thoracic region 

 deeply sculptured. Color, shining black by transmitted light, with 

 golden brown colorations; of these there is a continuous line around 

 dorsal ridge of marginal rim; three pairs of transverse portions of 

 case on the thoraco-cephalic region, occupying almost the entire space; 

 latero-cephalad of the most cephalic of these and adjacent to marginal 

 rim is a large pair of conspicuous wedge-shaped places; near cephalic 

 end of case, on each side of the dorso-median suture, there are two 

 small circular places; caudad of these and nearer the suture there is 

 a pair of short oblique lines on each side, caudad of these is a pair 

 of small circular places, caudad of these is a l)roken oblique line on 

 each side of the suture; on the abdomen, caudad of each suture, is a 

 narrow space; cephalad of the vasiform orifice is a large crescent- 

 shaped place the central portion of which is contiiuied to the vasiform 

 orifice, and the vasiform oritice is of the same color. This coloration 

 is probably due to unequal chitinization of the case. Bod}" segmenta- 

 tion distinct; median and thoraco-abdominal sutures conspicuous, the 

 latter very sinuate and extending- to the marginal ridge. The dorsal 

 disk is slighth' larger than the ventral, and they are connected by 

 the marginal wax tubes, which are bent downward and iuAvard. thus 

 making an oblique rim. Crenulations of margin deep and round, as 

 wide as long; mesad of the end of each wax tube is a large pore. 

 The usual caudal hairs are long and delicate, the latero-caudal i)uir 

 shorter. Vasiform oritice small, tubercled, subcircular; operculum 

 relativeh' the same shape, filling the orifice; lingula minute, strap- 

 shaped, obscured bv the operculum. There are a pair of pores latero- 

 cephalad of orifice, which are probat)ly the follicles of the hairs 

 usually present at this place. E3^e-spots black, situated mesad of the 

 wedge-shaped transparent spot on cephalo-dorsum.
