Two type slides of this species received under different dates are 

 in the Bureau of Entomology collection. The species is also in the 

 collection from Matanzas, Cuba, and was collected by N. L. Britton 

 and Percy Wilson, September 9, 1903, and forwarded by Prof. F. S. 

 Earle. It was taken on Nectandra. 



Pupa case. — Size 1.056 by 0.832 mm. Shape oval, broadest 

 across the abdomen. Abdomen distinctly marked off from the 

 thorax, the suture separating them not curving distinctly cephalad, 

 as in some other members of the subgenus. Abdominal segments 

 flat. Color under microscope brownish black, with a pair of small, 

 clear, circular eyespots on the cephalic portion of the case. Dorsum 

 of case with a number of minute clear circular pores arranged as 

 shown in the figure. The submarginal row of these pores is a con- 

 siderable distance from the margin (0.096 mm.) and in this char- 

 acter is distmct from the two other closely related forms, oculireni- 

 formis and oculiminutus. The submarginal area between this 

 row of pores and the margin of the case is marked with a series of 

 lines and checks (pi. 59, fig. 14). The outer part of this fined area 

 is more than twice the width of the inner, while on the cephafic 

 portion of case there is sometimes part of a third series. Mesad 

 of this submarginal row of pores there is no checked area as in ocu- 

 lireniformis. The margin itseff is armed with a closely appressed 

 series of evenly rounded shallow teeth, and the teeth of the comb at 

 the ending of the thoracic folds are scarcely distinguishable from the 

 remainder of the margin (pi. 59, fig. 13). Vasiform orifice (pi. 59, fig. 

 12) usual, more elongate than that of the type. 



Adults. — Unknown. 



Type.~Cat. No. 19207, U.S.N.M. 



Orchamus, new subgenus. 



Pupa case flat, thoracic and caudal folds more or less distinct; vasi- 

 form orifice rounded, and armed with a series of teeth on its inner, 

 caudo-lateral margin. Shape of case usually elliptical, not twice as 

 long as broad. 



Type. — Aleuroplatus (Orchamus) mammaeferus Quaintance and 

 Baker.

This species is represented in the bureau collection by only one lot 

 of material taken on Codiaeum variegatum Linnaeus in January, 1911, 

 by R. S. Woglum. It was collected at the Botanical Gardens, Buiten-
