BORNEAN DRAGONFLIES. 69 



Wings of a smoky tint, without any basal colour. 



Front of head entirely russet-brown, with metallic-green reflex 

 above ;. occiput black. Prothorax dark brown. Thorax brown 

 with a faint metallic-green reflex, antealar sinus bright brown. 

 The lateral stripe is of a pale brown colour, and is bordered on 

 either side with more richly metallic colouring. 



Abdomen entirely bronze-black, except for a square yellow 

 mark on the base of segment 7 occupying not quite a tbii'd of the 

 length of the segment. The first four segments have a strong- 

 metallic lufstre, the rest are duller. 



Legs black, slender. 



In the present specimen the span of the fully extended fore 

 wings is 125 mm. 



5. Macromia cincta Ramb. 

 1 d" . Baram. 



Length of abdomen 49 mm., of hind wing 45 mm. 



This specimen agrees exactly with de Selys's account of 

 M. cincta, save that segments 6 and 7 of the abdomen are 

 entirely black. 



[iVo^e.— -The large female Macromia described above has 

 certainly a very close resemblance to M. westtooodi, especially in 

 the colouring and in the absence of a basal mark to the wings. 

 De Selys described M. westwoodi $ as having "deux large bandes 

 antehumerales fauves," a description which would scarcely apply 

 to the specimen I have described. It is further very considerably 

 larger, but the range of size in species of this genus is not well 

 known so far as Oriental species go, so that whilst I incline to 

 believe that Mr. Moulton's specimen represents an undescribed 

 species, I feel bound to await further material before describing 

 it.] 



M. gerstaeckeri is readily distinguished from other Bornean 

 species by its relatively small size (span about 70 mm. in the 

 male, 80 mm. in the female), by the possession of a narrow yellow 

 antemedial line, incomplete above, and by the position of the 

 external tooth on the ujDper anal appendages of the male, nearly 

 at the extremities of the appendages instead of being at their 

 middles, as in the other Bornean species so far as is known. 

 Further, it has a yellow band across, the nasus. I confess that 

 the position of M. horneensis Kriiger seems to me a little 

 doubtful, it certainly comes very near M. cincta. It is im- 

 possible, however, to study these species satisfactorily without 

 the advantages of having a good series before one. M. cingidata 

 Ramb., with much yellow on the face and abdomen, is very 

 distinct. 



Genus Epophthalmia. 



6. Epophthalmia austealts Hagen. 



I have examined a young male of this species, collected by
