62 THE KNTOMOLOGIST. 



3. Ventral surface dark. India : Kurseong 3. compar (White). 

 3a. Ventral surface pale ....... 4. 



4. Base of pronotum practically uninterruptedly black, 



straight ; anterior femora not incrassate ; first ven- 

 tral "genital" segment not visible above. South 

 Africa ....... 4. distanti, n. sp. 



4a. Pronotum black, with a "C3" on each side pallid; 

 femora subincrassate ; first "genital" (ventral) 

 segment visible above. India, Ceylon . 5. stall (Dohrn). 



The pattern in both sexes is very similar. 



1. M. Utitratiis (Stal). — The colours in the female are brighter 

 and more distinct than in the male. The type is in the Stockholm 

 Museum, and was from Wampoa ; I have it from Hongkong. 



2. histrio (^V^hite). — This species I know only by White's 

 description. I believe the type is in the British Museum. 



3. compar (White). — This was recorded by White from " India." 

 Through the kindness of my friend Mr. G. Severin I have seen 

 some examples in the Brussels Museum, from Kurseong. I 

 believe the type is with M. histrio. 



4. stali (Dohrn). — Of this I have seen specimens, both 

 macropterous and apterous, sent to me by my friend Mr. E. E. 

 Green from Ceylon (Pundaluoya), from sheltered pools in rocky 

 streams ; my friend Mr. M. Burr has also given me examples 

 from Assam, Chenapunghi (Khasia Hills). The type appears to 

 be lost. 



5. distanti, n, sp. — This species may be best described by 

 comparison with M. stali. As I believe Mr. Distant will describe 

 in detail and figure it, I need only point out the salient cha- 

 racters. 



The colouring and pattern in these two species is almost 

 identical, except that the pallid markings on the mesonotum are 

 more rounded exteriorly in stali, more angular in distanti. The 

 base of the pronotum in distanti is practically uninterruptedly 

 pale, while in stali there are two rounded pale markings ; the 

 pale marks are also redder in the former. The form of the 

 "genital" segment is also very different ; in distanti it is sub- 

 triangular, while in stali it is subrotundate ; in the latter the 

 apex of the " sixth" is almost truncate, and of the " seventh " is 

 widely bisinuate ; in the former the apex of the "sixth" is 

 apico-laterally produced subrotundately, obtuse-angularly, and 

 the " seventh " is truncate.
