The wings are somewhat bent down at the tips. The antennae 

 extended forward. 



The full-grown larva (Plate III, Fig. 3) is about 15 to 18 mm. 

 long, dull dirty white ; finely pubescent, except head and segment 

 two ; head and cervical shield blackish-brown ; tubercles slightly 

 infuscated, especially those of segments two to four ; tubercles 

 i and ii in a straight longitudinal line, iii separated into two 

 above the spiracle, iv and v below spiracle and about as far 

 apart as iiia and iiib above ; spiracles pale with black margins. 

 Like Erciiiictis larvae, they are of slow growth; the length of 

 larval period has not been definitely determined. 



The pupa (Plate III, Fig. 2) is 6-6.5 "i"^- i" length; nearly 

 uniform light brown, paler below, darker at extreme anterior 

 end ; fine hairs are situated where they were on the caterpillar ; 

 head bluntl}-, triangularly produced in front near ventral side : 

 all of the al)dominal segments miovable, except first and second ; 

 near basal dorsal margin of segments four to eight is a slight 

 transverse ridge armed with a row of numerous siiort spines, 

 which assist in emerging from the cocoon at the time the moth 

 emierges : cremaster has two short, stout spines on dorsum and 

 slightly curved forward, two slight conical protuberances on 

 ventral side ; antenna- wing- and leg-cases extend to near middle 

 of eighth abdominal segment, free beyond third segment. 



The pupa is formed in a compact cocoon made in the place 

 where the larva has fed. The cocoon is about 8 mm. long by 

 2.5 mm. in diameter, rounded at the ends and covered with frass 

 and other debris, few fibers of the cane or leaves, etc. ; at each 

 end, a strip of white silk extends out about 5 mm. onto the sur- 

 face of whatever the cocoon is attached to. About ten days are 

 passed in the pupal stage. 



Opogoiia apicalis n. sp. 

 (Plate HI, Figs. 4 and 5.) 



Antennae ochreous-brown, banded above with fuscous, basal segment 

 fuscous-brown above; palpi brownish-ochreous, darker on outer side, a 

 few large bristles on outer side of median segment ; head tufted above 

 with ochreous-brown hairs, smooth-scaled in front, ochreous ; back of 

 head, thorax, and patagia, dark fuscous-brown ; forewings fuscous-brown 

 mixed with a few ochreous scales, an ochreous spot on dorsum near base,
