MR. F. F. LATDLAW ON 



to E. cuGullata Selys. I have examined a series of specimens ( rj ) 

 from Lio Main and Tatau. 



126. RiiiNOCYPHA sp. B. (Text-fig. 2.) 



The i"emarls:s made on the pi'evious sj^ecies refer also to the 

 present one, wliieh appears to he allied to R. mouUoni. 1 have 

 seen 5 specimens from Mt. Batu Lawi, all males.

Lateral view of colour-pattern of abdomen of Rhinocyi^ha sp. B. 



[The primitive marking of the abdomen of the genus RMno- 

 cypha, and perhaps of Microvierus, is probably a series of paired 

 dor.sal marks, and outside these on either side a series of lateral 

 markings, the latter originally possibly a line extending along 

 the length of the segment, but now in many cases broken up into 

 anterior and posterior spots. 



The species which in this paper I refer to as Rhinocyjyha sp. A 

 seems to preserve the primitive colouiing to a faiily typical 

 extent ; this is also the case in R. onotdio'iii and in Rkmocypha 

 sp. B. Other species show various modifications of the colour- 

 pattern, which, it may be noted, may be either blue, orange, red, 

 or yellow, Thvis, in R. cucullata for example, in the males only 

 the lateral colour-marks are retained, save on segments 8 to 9, 

 which have also dorsal markings. In R. aurulevtus Fbi'ster 

 from Buru only the lateral marks are retained ; whilst in the 

 exquisite R. iridea Selys from Burma only marks belonging to 

 the dorsal series are to be seen. Lastly, in some presumably 

 specialized forms — e. g., R. stygia Forster — these markings have 

 disappeared altogethei-.]
