1902.] DRAGOXPLIES OF THE "SKEAT EXPEDITION." 77 



species, at Kwala Aring in September 1899. The male is very 



young. 



6. ?. 



Length of abdomen (without appendages). 36 mm. 37"5 mm. 



Hind wing 32 34 



Pterostigma 2 2 



c? . Antenodal nervures of fore wing 14, postnodal 7, 3. Ante- 

 nodal nervures of hind wing 11, postnodal 7, 8. Supra-triangular 

 nervures of fore wing 3 or 4, of hind wing 2. Nerves of median 

 space of fore wing 6, of hind wing 4. 



The head in this specimen is badly shrivelled, and it is difficult 

 to make out the characters for the most part ; the yellow ' nasus ' 

 is obvious. 



Prothorax dull brown. Thorax iridescent brown, with three 

 yellow lines on each side. The antehumeral band begins at the 

 base of the coxse of the first pair of legs and runs about halfway 

 up the thorax. The middle line commences behind the middle 

 pair of legs and runs up to behind the front pair of wings, running 

 right across the back to join that of the other side. The hinder 

 stripe runs along the hinder outer margin of the abdomen, 

 starting from behind the last pair of legs. The coxje of the 

 first pair of legs are yellow, as also the hinder surface of those of 

 the second and third pairs. 



The abdomen is dull brown ; segments 1-3 and 7-10 a little 

 expanded. It has yellow markings as follows : — base of the first 

 segment shading gradually into duU brown at its hinder end, 

 second segment has a yellow ring covering its anterior half ; 

 third segment has two very small dorsal spots lying very close 

 together just behind the middle of the segment ; seventh seg- 

 ment with a transverse dorsal band taking up the anterior fifth 

 of the segment. 



Anal appendages subequal, or the inferior a very little larger 

 than the two upper, about 3 mm. long, as long as the last two 

 segments. The upper pair have each at about two-thirds of their 

 length a small tooth on the outer side. 



2 . Head and thorax as in the male, but the iridescent brown 

 is replaced in the more adult female by rich metallic green. The 

 wings have a number of vague brown marks on their outer 

 halves. 



Abdomen. Segments 1-6 metallic black, 7-10 dull black. 

 Yellow markings as follows : — second segment a long spot on 

 either side, a transverse line along its anterior margin dorsally, 

 two small dorsal spots at about the middle of the segment ; 3 with 

 a line on either side along its lateral anterior margin not reaching 

 the dorsal surface ; 7 as in the male, bvit the yellow mark is 

 broader, covering about one-fourth of the segment. 



As Kriiger has pointed out [loc. cit.), M. gerstaeckeri difiers 

 from its allies in its smaller size ; and in the position of the small 

 second tooth of the superior anal appendages of the male from the
