nigro-annulata, Wulp, cf 5 . Morotai. A type cf in good 

 condition and two 9 9 in fair condition determined by the 

 author of the species are in the Ley den Museum.

Four species have been comparatively recently described by 

 Meijere^ from Java, the types being in the Amsterdam Museum. 

 These are dorsalis 9 , fallax & 9 , scurroides 9 , and dimidiata $ , 

 but fallax, as noted above, is now considered by its author 

 synonymous with doleschalli, Os. Sac. He describes the cf of 

 scurroides subsequently.^ 



N.B. — Although no species is definitely here sunk as a syno- 

 nym, it is possible that further study of this genus may reduce 

 their number. Many of the species are described from single 

 specimens, and nearly all of them seem likely to prove variable ; 

 in fact since working at the Oriental Tipulidae Pachyrhina has 

 always proved the most refractory genus of all. 



Pachyrhina doleschalli, Os. Sac. 



Tipula javensis, Dol. 

 Pachyrhina fasciata, Macq. 



I think there can be no doubt that three 9 9 in the Indian 

 Museum are this species and that it is very variable. Osten 

 Sacken surmised as much , noting the variability of the abdominal 

 marks and the spots on the pleurae ; whilst various remarks in the 

 three different descriptions of this species (Doleschall's, Macquart's 

 and Osten Sacken' s) support this view. The three examples 

 before me are distinctly /t^mo w-yellow, especially on the thorax, thus 

 agreeing with Doleschall's " citrino-flavo," Macquart's remark 

 that the metathorax is all yellow is probably an error for metano- 

 tum, which in one of the three specimens is ver}^ conspicuously 

 lemon-yellow, unmarked, in another bright lemon-yellow with an 

 orange hind border, and in the third orange with a blackish hind, 

 or rather lower margin. The scutellum also varies, being in two 

 specimens shining black, in the third shining brownish yellow, 

 sublucid. The abdominal marks are quite certainly very variable. 

 The first example has the basal segment black, a broad black band 

 on hind margins of 2nd and 3rd segment, a narrow one on 

 the 4th and 5th, the 6th being mainl}^ blackish. In the 

 second specimen the only black is the tips of the 2nd and 3rd 

 segments, the whole of the 6th and the base of the 7th. In the 

 third specimen the marks are similar, but narrower, and rather less 

 intense. The fore femora have a broad blackish central band 

 which is quite distinct in one specimen, much less so in the 

 second, the third having these legs missing. This character has
