Habitat : Indien. 



M u Lachlan, loc. cit. : 



Atr.i subnitida; capite infra in medio poulo rufescente. Antennae 24-articulatae, nigrae; articulis 

 5-6 ultimis flavidis, ultimo parvulo. Pedes nign, fusco-pilosi, tarsis subtestaeeis. Alae nigro-fuscae, albido 

 4-striatae; venis plerumque nigris. Long. corp. 10 ' _.""". Exp. alar. [8 mm . 



Habitat : in India Orientali. 



Deep black, somewhat shining. Head elongate with a large, nearly circular, shallow depression on the 

 disk above; eves large, beneath the portion below the labium, joining mi to the neck, is redaish. Antennae 

 black, with black hai'rs, 24-jointed, the tsl Joint large but short, 2nd very small, ;rd nearly as Ions as the 

 tst aml 2nd united, the sueeeeding two or three joints rather short; but afterwards they became elongate; 

 dually decreasing in length near the apex, the apical five joints yellowish, and the 6th from the apex also 

 tmged with yellow, the terminal Joint small and obtuse : in length the antennae nearly equal the head and 

 thoras united. Maxillary palpi stout. the last two joints longer than the others. Pronotum much narrowe«! in 

 front, nearly twice as long as broad. Meso- and metanota nearly equal. Legs black, with blackish Hairs; 

 knees and tarsi somewhat testaeeous. Abdomen black, with black hairs; caudal processes long, bul verj 

 asymmetrical, black, with black hairs; the righthas the basal Joint very broad, nearly quadrate; whereas in 

 the left it is -lender and lullv twice as long; a slender process with pieeous apex projeets from the baseol the 

 right; ventrally is a large triangulär proiection of the last segment, coneave above. Wings narrow, dark 

 smoky fuscous^ the membrane transversely rugose (but not visibly tuberculate); the costal margin appears 

 darkei in consequence ol the thick, black', coalescent subcosta and radius; the oblique postcostal vein also 

 thickened and deep black; the sectoi deep black and strong, the other veins fine and inconspieuous ; 

 4-; evident pale costal veinlets, and three veinlets in both pairs between the radius and the uppei bran< h ol 

 the sector; but there are no other transverse veinlets; hence the discoidal cell is open; four very narrow 

 whitish longitudinal lines A well-grown Iarva is i2 mm long. The antennae much shorter than in the imago. 

 The colours generally lurid-fuscous rather than in the imago. The colours generally lurid-fuscous rather than 

 blackish, with the posterior portion of the head, the whole prothorax, and the legs more oi leFS testaeeous; 

 and the whole underside is pale; the abdominal segments above with a brownish tinge, clothedwith sparse 

 yellow ish hairs ; the caudal appendages present ; just the same asymmetry as in the imago. 



A starved « nymph » is only 9""" long. The colours similar to those of the Iarva : and the form also 

 nerally similai ; bul tne legs are more slender (as in the imago), the asymmetry in the caudal appendaj 

 striking (is it ol the same sex ?). The rudimentary wings elongate oval, with evident neuration, characte 

 ristic of the genus; the anterior extenting to the posterior margin ol tue metanotum, Tue posterior to the 

 posterior margin ol the second dorsal abdominal segment. 



flu- is the species alluded to at the commencemenl of this paper, found by Mr. Michaej in one ol 

 bis hothouses among plants of Saccolabium retusum imported from India. In its wing-strueture it agri 

 generically with O. Saundersi, «mich is also an Indian species. »
