Amboina (D. latieeps). As Dr. Semper's collection contains two species 

 of the same genus, I avail myself of the opportunity for characterizing 

 it more completely. 



Closely allied to Damalis, but easily distinguisted by the structure 

 of the third antennal Joint, which is much longer than broad, lamelli- 

 form, sublinear, and bears an arista at the tip, which is a little shorter 

 than the Joint itself; the joints of the scapus are short, bristle-bearing, 

 the second subglobular. 



Minor differences from the five asiatic species of Damalis which 

 I bave before me consist in the following: the anterior crossvein is 

 about the middle of the discal cell, and not beyond it; ^) the fifth pos- 

 terior cell is not in contact with the discal; the proximal end of the 

 first submarginal cell is distinctly more proximal than the proximal end 

 of the discal cell; the swelling of the lower part of the face is more 

 abrupt, and the mystax consists of a greater number of bristles, The 

 cilia of the posterior orbit, although very weak, are a little more 

 developed here than in Damalis; the trochanters of the bind legs are 

 less developed, the bind femora less stout and unarmed. The venation 

 is very like that of Solopogon. 



D. latieeps Dol., of which I possess an excellent colored drawing, 

 agrees in the generic characters with the two species described below. 

 In the specific characters, it seems to hold the middle between them, 

 as it has the brownish thorax of D. Semperi and the metallic-blue 

 abdomen of D. cyanella. My specimen of the latter shows a remarkable 

 peculiarity in its venation: it has only four posterior cells, instead of 

 five, because there are only two veins issuing from the end of the dis- 

 cal cell, instead of three. As I have only a single specimen, and as 

 that specimen has only one wing left, I am not sure whether this 

 peculiarity is not an accidental abnormity. Should it even prove a 

 permanent character, it would not be a sufficient one for the formation 

 of a new genus, as, in other respects, the agreement with C. Semperi 

 is perfect. 



I do not find Damalina mentioned in any of Dr. Schiners lists; 

 it seems to have been overlooked since its publication. 



Damalina Semperi n. sp, $. Antennae black; arista reddish; 

 head clothed with a fulvous pollen; thorax clothed with a fulvous poUen, 

 or rather a microscopic fulvous pubescence; mesonotum dark brown in 

 the middle, the outline of which color represents the usual thoracic, 



^) Damalis marginata v. d. Wulp, Tijdschr. etc. XV, 142 shares 

 this character with Damalina.
