greenish , rather than bluish ; there seems to be some yellow 

 on the venter. The comparison of a larger number of well- 

 preserved specimens would probably disclose other differences. 



Hah. Ajer Mantcior , Sumatra, August 1878 {Beccavi); one 

 c/', two 9 . 



Calobata lunaria n. sp. A little smaller than C. albimana. 

 Front metallic blue ; the round velvet-black spot is drawn out 

 posteriorly in a point, which includes the ocelli ; beyond this 

 point the vertex and occiput are metallic- blue, shining. Mentum 

 and palpi brown ; antennal scapus and base of the third joint 

 reddish , the rest brown (in one of the specimens the whole 

 antenna is nearly brown). Thorax blackish-blue , thinly whitish 

 hoary ; it is subopaque on the dorsum, where three longitudinal, 

 linear, blackish, opaque stripes are visible ; the pleurae are more 

 shining. The fan-like row of hairs above the middle coxae is 

 black. Halteres with a black knob. Abdomen , like the thorax , 

 of a blackish-blue and whitish hoary color ; a smoky black sub- 

 opaque crossband on the second segment , and a similar , but 

 broader crossband occupying a considerable portion of segments 

 3 and 4. Front coxae black, with a bluish reflection and whi- 

 tish lioary ; front legs dark brown ; tarsi white from the tip of 

 the first joint ; middle and hind femora dark brown ; both with 

 a narrow reddish ring a short distance before the tip ; the ex- 

 treme base of the hind femora is yellow. Wings with a brown 

 crossband between the tip of the anal cell and the anterior 

 crossvein ; it becomes evanescent before reaching the posterior 

 margin ; the remainder of the wing , soon beyond the anterior 

 crossvein , is brown , except a crescent-shaped hyaline spot , 

 which begins at the end of the second vein and does not quite 

 touch the posterior margin (at least in fully colored specimens) ; 

 this crescent thus cuts off a second , broader crossband , the 

 rounded sides of which impart to it a somewhat circular appea- 

 rance. The first posterior cell is closed , and even slightly pe- 

 tiolate. 



Hah. Ternate {Beccavi 1875) ; four specimens.
