398 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.51. 



Adult female. — Similar in color to the male. The hindwings some- 

 times have transparent patches. Length 0.96 mm.; forewing 0.848 

 mm. The females, as in the males, lack the antennae. 



Described from pupa cases, males and females in balsam mounts, 

 and pupa cases dry on foUage. 



Type.— Ca.t. No. 19204, U.S.N.M. 



The adults of this species arc very similar in many ways to those 

 of Aleurocantlius citriperdus. The red color met with in this species 

 as against the yellow color in citriperdus is not always a good distinc- 

 tion. In citriperdus, however, the claspers of the male possess fewer 

 spines, and are less curved at their distal extremities. 



ALEUROPLATUS (ALEUROPLATUS) VALmUS, new species. 



Plate 61, fig. 1; plate 59, figs. 5-7. 



This species was received from Prof. S. F. Ashby on April 30, 

 1914, marked Hope, Kingston, Jamaica, host unknown. It is more 

 nearly related to quercus-aquaticae than to any other species of the 

 genus, but may be distinguished from it by the presence of promment 

 dorsal thoracic spines and by the character of the suture between 

 the thorax and abdomen. 



Pupa case (pi. 61, fig. 1). — Size 0.96 by 0.72 mm. Shape almost 

 elliptical, with a slight constriction across the thorax at the region 

 of the thoracic folds. Color brown, sometimes with a darker pig- 

 mentation along median area and around suture separating thorax 

 and abdomen. Eyespots irregular, smaller than in quercus-aquaticae; 

 extremities of thoracic folds not heavily pigmented. Form flat, the 

 abdominal segments distinct only on the median dorsal area. Suture 

 separating thorax and abdomen curved cephalad almost to the mar- 

 ginal extremities of the thoracic folds. In this character the species 

 is similar to quercus-aquaticae. The suture is cui-ved as far cephalad 

 as in the type-species, but after leaving the median suture it is not 

 curved as much caudad before its cephalic recurve as in that form. 

 Thorax with two pairs of prominent clubbed spmes, one pair on the 

 median portion of each of the two caudal segments. Pores of the 

 submarginal area arranged in groups very similar to those of quercus- 

 aquaticae. Comb of the thoracic fold (pL .59, fig. 7) anned with 

 usually four teeth, which are very little larger than the other mar- 

 ginal teeth (pi. 59, fig. 5). Vasiform orifice (pi. 59, fig. 6) usual, 

 if anything shghtly more elongate than in quercus-aquaticae. Other 

 characters, including waxy secretion, quite similar to those of that 



Adults. — Unknown. 



Described from pupa cases in balsam mounts.
