MonophlebincE. 433 



tion was drawn up from specimens received from Ceylon. It appears that the 

 type specimen is ex coll. Gumming, whose collection was purchased partly 

 from Fortune (whose material was gathered in North China) and partly from 

 Thwaites (from Ceylon). It seems possible, therefore, that there may have 

 been some confusion in the registered locality of this particular type. However, 

 there is nothing impossible— or even improbable — in the same species ranging 

 from Ceylon to China. I feel convinced, at least, that my specimens are 

 equivalent to contrahens as determined by Signoret. 



MONOPHLEBUS FURCATUS, sp. nov. 

 (Plate CLXXVII.) 



Adult male [fig. i) dull brick-red, pruinose ; notal plates darker ; scutellum 

 pale reddish brown. Wings ample, dull black, with a greyish bloom ; costal 

 nervure pale brown, second nervure deep black, the interneural folds white ; 

 minutely rugose between the nervures (see j^. 4). Halteres ( y'^^i'. 5, 6) with 

 six (rarely five only) stout hooked bristles at the distal extremity. Antennas 

 dark brown ; ten-jointed ; basal joint short (see fig. 7), with scattered short 

 hairs ; second joint approximately twice as long as the first, with scattered long 

 hairs ; other joints elongate, tri-nodose, with a whorl of long hairs on each 

 node. Compound eyes black, moruliform {fig. 8), the facets large {fig- 9) ; a 

 prominent simple ocellus above the inner edge of each eye. Legs reddish 

 brown ; tarsus straight or slightly curved {fig. 3), with a sharply demarked 

 triangular segment at its base ; rather les^ than half the length of the tibia ; 

 ungual digitules long and slender, simple. Caudal appendages (one on each 

 side) wrinkled ; with comparatively short hairs. Dermal pores {fig. 10) with a 

 central orifice surrounded byfour or five large translucent cells. Length (without 

 appendages) 4*5 to 6 mm. Expanse of wings 10 to 13 mm. Length of antennas 

 4'5 to 5 mm. Length of caudal processes i to r5 mm. 



Taken at high elevations only : Pattipola, Pundaluoya, Maskeliya. 



It is possible that this insect may be identical with Moii. atripennis of Bur- 

 meister from Java. 



MONOPHLEBUS VARIEGATUS, sp. 7iov. 

 (Plate CLXXVII I.) 



Adult male {fig. i) ; head and thorax yellow, eyes crimson ; mesonotal 

 plates shining black, with a large, lunate, clear, central space ; posterior 

 segments of abdomen dull crimson ; legs and antennae black ; wings deep slaty 

 black, dull, the interneural folds whitish. The abdomen is narrowed at the base, 

 widening posteriorly (see fig. 2) ; the extremity with two elongate, wrinkled, 

 hairy, fleshy appendages on each side. Antennas ten-jointed ; the basal joint
