OF WASHINGTON. 449 



Egg- Cup-shaped, rounded below, flattened and a little hollowed above, 

 with a. central, rather large pit at the micropyle. Pale violaceous, very 

 minutely reticulate. A series of strongly raised white lumps, somewhat 

 crested, largest about the upper rim, smaller below, smallest on the flat 

 tened upper surface, connected by a series of raised white lines, six to eight 

 radiating from each lump and passing up the bases of these prominences 

 for a short distance, thus forming areas between the prominences. Di 

 ameter .5 mrn. 



Food plants : Guilandina bonducella, Pithecolobium guad- 

 aloupense. 



PlERID^E. 



Callidryas eubule Linn. Frequent in 1890, less common in 

 1900. I did not find the larvae. 



Callidryas agarithe Bd. Somewhat less common in 1900 

 than in 1899. Several examples were seen, however, flying on 

 the warmer bright days. The larva feeds on the young tender 

 leaves of Pithecolobium guadaloupense. (See Ent. News., xj, 

 6 1 8, 1900). 



Callidryas statira Cram. Rare in 1890 ; not seen in 1900, 

 I think. It would be necessary to net all the yellow Callidryas to 

 be sure there were no statira, as they greatly resemble eubule 

 on the wing. 



Tacky r is ilaire Godt. Very abundant in 1890; only a few 

 examples in 1900, but these were fresh. 



Pieris monuste'Lmn. Common in 1890, entirely absent in 1900. 

 The food plant, Bursa, was growing commonly on waste land, 

 but no trace of this larva in the latter year.* 



Terias lisa Bd.-Lec. Several examples seen in 1900. I do 

 not recall the species in 1890, though it was common then further 

 north. 



HESPERIID^E. 



Pamphila accius Sm. and Abb. A few examples. 



Pamphyla osyka Edw. Less common than the preceding. 



Pholisora hayhurstit Edw. Very common in 1890; the larvae 

 on Alternanthera flavescens (see Ins. Life, 111,389). Compar 

 atively few examples in 1900, and no larvae found. 



Erycidesbatabano Lef. Larvae not uncommon on the mangrove 

 in 1890 a few imagines seen. None in 1900, but some signs of 

 the larval houses on the leaves. (Larva described Can Ent xxii, 



211). 



Megathymus yuccce Bd.-Lec. Mrs. Slosson took two in 1900. 



*In the following May, Mr. Kinzel sent me the larvae feeding on Cup- 

 part cynophalophora.
