that it is so, I am rather inclined to believe that this locality h 
neous, and that the insect is, in reality, Indian. It is allied to tu 
latus and inquinatus (the next described species), differing froi 
former in its larger sige, broader aspect, and in the lineated sub- 
area; its differences from inqxdnatus are noted in the following, 
parative diagnosis. ^ 
OSMYLUS INQUINATUS, n. sp. 
^ O. interlineato similis ; sed alls sine punctis discalibus, antii 
area suh-eostali, areaque inter sub-costam et radium, fasciis duabus 
bus transversaUbus,puncto inter fascias, strigisque duabus apicem v 
sordide aureis, mow distinguitur.

In Mus. Brit. 
This species, collected in Ceram, by Mr. Wallace, has the foi 
tnterhneatus, but is apparently abundantly distinct in consequer 
the dull golden markings of the anterior wings. 
O. tuberculatus, interlineatus, and inquinatus, are no doubt cl 
allied ; yet I cannot consider them as only forms of one species 
doubt not that more extensive materials will prove their specific v 
Possibly also the raised spot of the wings, and somewhat diff, 
general appearance, may eventually cause them to be generically i 
rated from the other species of Osmylus. The claws in O. tubercu 
are distmctly bifid at the apex, and the same character doubtless ob 
m the two others ; but the single specimens of each of these are n, 
a condition for minute examination.

This genus is formed for the reception of Osmylus pundipen 
Walker, and differs especially from Osmylus (as here restricted) in 
costal veinlets being united so as to form several irregular rows of se 
cellules.
