ascertain with certainty its identity with T. immisericors. There is nothing in 

 Doleschall's inadequate description o£ 31. subulifer to separate it from T. 

 immisericors, and if this species is found to occur in Amboina the older name 

 subulifer will have to be used for it. Doleschall, however, described quite a 

 different species (M. amboinensis) which he afterwards considered to be the male 

 of his M. subulifer ; if his opinion was correct, M. subulifer is distinct from T. 

 immisericors, and on account of this possibility the name under which this species 

 is now widely known is retained for the present.

 If Theobald had seen Leicester's work he could hardly have failed to recognise 

 that he was redescribing T. quasiferox. The only difference discoverable in the 

 descriptions is doubtless due either to slight inaccuracy in Theobald's observa- 

 tions, or to fading after death. The caudal tuft of T. javaensis is described as 

 follows : " apical segment with a dense tuft of bright orange chaetae, some short 

 black ones at the sides of the previous one and some orange ones on the next." 

 In T. quasiferox the black hairs on the penultimate segment are quite as long as 

 the orange ones, and there are orange hairs at the base of this segment, not on the 

 apex of the sixth. The basal abdominal segments of the British Museum 

 specimens of T. quasiferox have faded to an "apple-green" as in T. javaensis. 

 There are a number of small but constant differences (e.g. the white tip to the 

 front tibiae), which need not be here enumerated, between this species and T. 

 immisericors. 



5. Toxorhynchites magnificus (Leic). 



Teromyia magnijicus, Leic, Cul. of Malaya, p. 54 (1908). 



Teromyia funestus, Leic, Cul. of Malaya, p. 58 (1908). 

 An examination of the type male of T. funestus, presented by Dr. Leicester 

 to the British Museum, shows that his description was slightly inaccurate. 

 According to this description " all the legs [apart from the coxae, are] brilliant 

 purple, the only attempt at banding being an imperfect band on the first [i.e. 

 second] tarsal joint of the hind legs." In the type there are however distinct 

 traces of white marks on the under sides of the hind tibia and metatarsus in 

 exactly the same positions as in T. maan'ificus. In addition to this, the scales of 

 the mesonotum and first abdominal segment now appear coppery and not greenish, 

 but this is doubtless due to post mortem changes ; all the specimens of T. magnifi- 

 cus have these scales metallic greenish, as described both for this species and for 

 T. funestus. I therefore conclude that the specimen described as T. funestus is 

 really only a dark form of T. magnijicus. The commencement of the 

 caudal tuft is white in both.
