44 CLASSIFICATION OF THE ALEYRODID^. 



3. Submarginal area of pupa case without a band of small simple pores, 

 but just within the margin all around, one row of disk-like sim- 

 ple pores. Forewiug of adult with four more or less distinct 

 dusky areas, one within the radial fork, one on either side of 

 the union of radius i and radial sector, and one on the proximal 

 costal margin. Waxy secretion composed of distinct fine rods. 



tiHnidadensis. 



II. Pupa case with six pairs of compound wax pores, there being five pairs of 



abdominal pores, of which the caudal pair is reduced. 



A. Case with marginal row of large simple wax pores, bearing within several 



fine rods; margin itself entire and just within it a row of 

 prominent hairs. Compound wax pores with the spinnerets much 

 reduced and short; lingula spatulate, very long and large, being 

 about three times as long as the operculum, armed with four 

 stout hairs. Size of case 1 by 0.84 mm., shape broadly elliptical. 

 Length of forewing (female) 2 mm. Wings banded with dusky, 

 as shown in Plate XXII, figure 5 ornatus. 



B. Pupa case without a marginal row of large, simple wax pores, but the 



submarginal area covered with numerous very small pores; 

 margin entire; caudal margin of case with two large spines. 

 Compound wax pores with the central process about the same 

 height as the cup and the spinnerets not reduced and short, but 

 about two-thirds the length of the central process. Lingula very 

 long, spatulate, armed with four hairs. Caudal margin of 

 operculum with two spines or hairs situated near the center. 



jamaicensis. 



III. Pupa case with five pairs of compound wax pores, there being four 



abdominal and one cephalic pair, all of which are equally de- 

 veloped. Margin of case entire; just within it a row of large 

 simple pores; smaller pores similar to these are scattered OA-er 

 the entire dorsum; lingula very long, narrow, tapering, and 

 armed with four hairs. Size of case 1.25 by 0.S5 mm.; shape 

 elliptical; waxy secretion fairly abundant, semiflocculent or 

 cottony, and more or less hiding the insects beneath__c-occo/o&cc.
