than to any other species. Perhaps they are evidence of the 

 occurrence of 0. abbotii in Cuba. 

 Material examined. — 12 cases: 



Cuba: Havana, 12 cases, DEI. 



Case No. 5 

 Figure 142 



Case. — (Fig. 142.) Length main body of case 20-25 mm. ; diameter 

 approximately 6 mm., uniformly cylindrical throughout length. 

 Structm'e of case consisting of a tightly appressed covering of 10-12 

 elongate twigs, arranged longitudinally; a few twigs projecting con- 

 siderable distance posteriorally, total length more than 40 mm. 



Recorded hosts. — None. 



Discussion. — The two specimens described here already have been 

 mentioned under ^'Chalia" dispar, which they resemble very closely. 

 Since no adult males of either species are known, to make a specific 

 comparison is difficult, but probably they belong to the same genus, 

 if not to the same species. The proper generic name and position 

 for these two larval cases, like that of "CJialia" dispar, await the 

 discovery of the adult moth. 



Material examined.— 2 cases: 



Brazil: Rio de Janeiro, 2 cases, collected by R. Fischer, DEI. 



Case No. 6 

 Figure 143 



Case.— (Fig. 143.) Length 12-14 mm.; diameter 2-3 mm. Ex- 

 terior of bag usually covered with long, slender stems of grasses 

 and other herbaceous plants, applied longitudinally, frequently ex- 

 tending entire length of case, sometimes projecting in irregular fashion 

 beyond posterior end. A few specimens examined were nearly devoid 

 of larger stems, exposing underlying surface of case, which was densely 

 covered with minute plant fragments. 



Recorded hosts. — None. 



Discussion. — Of the species known to occur within the general 

 geographical area of this unidentified insect, "Clania" licheniphilus 

 most closely approximates it (at least in comparison with a few of 

 the above bags, which are nearly bare), but the two forms are beheved 

 to be specifically distinct. Structurally, these larval cases most 

 closely resemble those of Old World genera such as Fumaria and 

 Epichnopteryx. Eventually this unnamed series of cases may be 

 found to represent another example of the introduction of a Palearctic 

 psj'^chid into the New World. 



Material examined. — 8 cases: 



Haiti: Aux Cayes, 4 cases, March 15, 16, 18, AMNH. Petionville, 4 cases, 

 Jan. 26-28, 1922, 1500-3000 ft., AMNH.
