that it is so, I am rather inclined to believe that this locality is erro- 

 neous, and that the insect is, in reality, Indian. It is allied to tubercu- 

 latus and inguinatus (the next described species), differing from the 

 former in its larger sige, broader aspect, and in the lineated sub-costal 

 area ; its differences from inquinatus are noted in the following com- 

 parative diagnosis. 



OSMTLUS INQUINAT'DS, 71. sp. 



O. interlineato similis ; sed alis sine punctis discalibus, anticarum 

 area sub-costali, areaque inter sub-costam et radium, fasciis duabus brevi- 

 bus, transversalibus, puncto inter fascias, strigisque duabus apicem versus, 

 sordide aureis, mox distinguitur. 

 Long. eorp. 4'" ; exp. alar. 19'". Eldb. Ceram. 



In Mu8. Brit. 



This species, collected in Ceram, by Mr. "Wallace, has the form of 

 interlineatus, but is apparently abundantly distinct in consequence of 

 the dull golden markings of the anterior wings. 



O. tuberculatus, interlineatus, and inquinatus, are no doubt closely 

 allied ; yet I cannot consider them as only forms of one species, and 

 doubt not that more extensive materials will prove their specific value. 

 Possibly also the raised spot of the wings, and somewhat different 

 general appearance, may eventually cause them to be generically sepa- 

 rated from the other species of Osmylus. The claws in O. tuberculatus 

 are distinctly bifid at the apex, and the same character doubtless obtains 

 in the two others ; but the single specimens of each of these are not in 

 a condition for minute examination. 



Htposmtltjs, nov. gen. 



Caput parvum : antennce breves ; ocelli supra et inter antennarum bases 

 2oositi ; labrum paxdlo emarginatum ; palporum maxillarum articuli duo 

 basales breves, cceteri longiores, inter se cequales, tiltimo acuto. Prothorax 

 latitudine paullo longior. Pedes pilosi, unguibus crassis, valde curvatis, 

 plantidis simplicibus. Aloe amplce: anticarum ared costali laid; venuloe 

 costales furcatoe, venulis obliquis plurimis, series areolarum plurimas forman- 

 tibus, connectce ; sub-costd et radio ad apicem confluentibus ; area sub-costalis 

 venuld und ad basin solum instructa; sectore et radio parcdlelis ; areolis 

 discalibus per-numerosis ; venulis marginalibus furcatis ; ared p)ost-costali 

 midti-areolatd : posticce fere ut in anticis, sed area costalis angustata, serie 

 areolarum unicd. 



This genus is formed for the reception of Osmylus punctipennis, 

 "Walker, and differs especially from Osmylus (as here restricted) in the 

 costal veinlets being united so as to form several irregular rows of small 

 cellules.
