LoeaUty. — Mexico. 



Mr. Schaus has observed the hirva of this species at Jalapa, Mexico, 

 many years ago, and has taken the following from his notebook: 



""Sibine exienm. Schaus, larva. Length 1 inch, very stout, ratlier scjuare, l)eing flat- 

 tened dorsally and laterally. Head, which is small and lirown with l)lack markings, 

 is concealed under the second segment. This segment is brownish with posteriorly 

 a subdorsal black and white spot. Body pale green. On segment 3 are four little 

 green tubercles, covered with short spines. On segments 4 and 5, only two similar 

 tubercles, but somewhat larger. Segments 11 and 12 the same as 4 and 5. Seg- 

 ment 13 has two large velvety brown tubercles; dorsally and posteriorly to these, 

 two small green, spiny tubercles. Laterally on eleventh is another velvety brown 

 tubercle. Lower down on segments 3 to 13 is a single row of little green spiny 

 tubercles, above which ground color changes somewhat to yellow and there is a tine 

 black lateral line. Prolegs yellowish. Live together in large numbers, and when 

 about to form cocoons, collect together on the bark and after spining a thin hard 

 web, form underneath it their cocoons, which are round and very hard. 



"Feeds on the smiquil chiefly. 



"Remain in larval condition all winter, becoming pupseonly a few weeks 'before 

 emerging.''

 subbasal dot large. Wings of the female with depressed apices; hind 

 wings of the male dark chocolate brown, the disk whitish to margin, 

 the shape somewhat trigonate, recalling EpiHihine., but the outer 

 margin convex.

Locality. — One male, one female, Hio Janeiro, Brazil (W. Schaus
