BY OTTO H. SVVEZEY. 



Omiodes maia n. sp. 



Male, female, 28-30mm.; head, thorax and abdomen dark fuscous 

 much mixed with ferruginous scales, especially on the abdomen; api- 

 cal margins of abdominal segments ochreous; antennae fuscous above, 

 pale beneath, basal joint fuscous; palpi fuscous, whitish below with 

 a slight ferruginous tinge anteriorly; femora and tibiae fuscous large- 

 ly suffused with ferruginous; tarsi ochreous. Forewings dark fuscous 

 suffused with ferruginous on costa, and less densely so near termen, 

 a few ferruginous scales scattered in some other parts of wing; a 

 whitish ochreous dash in middle near base; first line ochreous, angu- 

 lated outwardly (nearly at right angles) at middle, upper portion in- 

 distinct, lower portion very distinct; rou-ndish black orbicular; two 

 blackish discal spots transversely placed (mostly contiguous) fol- 

 lowed by a few ochreous scales; second line ochreous, sinuate out- 

 wardly beneath costa. below middle forming an acute triangular pro- 

 jection outwards; both lines often ferruginous mixed; veins marked 

 with ochreous or ferruginous ochreous; cilia fuscous, darker at base. 

 Hind wings medium fuscous, a darker discal spot and terminal dark 

 fuscous line; a paler postmedian line with acute projection outwardly 

 below middle, a few pale ferruginous scales in its dorsal part, a few 

 also just before terminal dark fuscous line, which is usually inter- 

 rupted by pale ferruginous scales on the veins; cilia as in fore wings. 



Very similar to O. musicola, bttt the latter is paler ftiscous. 

 and has ochreous suffusions and markings where maia is fer- 

 ruginous. 



I bred a series of moths on three different occasions, from 

 caterpillars found on bananas growing in two different gulches 

 at the head of Manoa Valley: Jan. 23, March 10* and May 2*, 

 1909, respectively. In one of the gulches, I found the caterpil- 

 lars quite numerous. 



Full-grown caterpillars are just like those of musicola. Some 

 have darker markings than others : markings of head quite black, 

 and wider black margins to cervical shield, the 'longitudinal bh?ck 

 bar joining it in front and behind, which gives the cervical shield 

 a very blackish appearance. Caterpillars just hatched have 

 heads entirely black; those one-third grown have most of the 

 tubercles black. 



Pupa similar to musicola. 



* These observations were made after paper was presented to So- 

 ciety.
