vein with the discal cell by means of the anterior cross- vein, a singularity 

 occurring with extreme rarity in Tipulidae, and normally in only one 

 oriental genus, Amalopis. It is by no means certain that a new genus 

 should not be set up for the present species.

The Elephantomyia group. 



The two or three genera with enormously produced rostrums, up to 

 nearly or quite as long as the body, may be considered separately from 

 the rest of the sub-family though they do not necessarily form a separate 

 group. Though they possess this character in common they vary in 

 important other characters, in the presence or absence of the submarginal 

 cell, and in the number of the antennal joints. The genera concerned 

 are Toxorhina, Loew ; Elephantomyia Os. Sac. ; Limnobiorhynchus, 

 Westw., and a new genus Conithorax. 



Whether the two first are synonymous I have no means of determin- 

 ing but it seems probable, judging from Osten Sacken's remarks in his 

 Monograj)h of the North American Tipulidae, since he referred Loew's 

 three fossil species of Toxorhina to his own genus Elephantomyia. In 

 the event of synonymity, Toxorhina takes precedence. The exact 

 application of the name Toxorhina is discussed further on. 



If the claim of Toxorhina to stand for the fossil species be admitted 

 there remains the question of a name for fragilis and its allies, and Ber- 

 groth would resuscitate Limnobiorhynchus, Westw. for these. The 

 justness of this seems obvious, although the name is applicable only to 

 the $ of Westwood's genotype brasiliensis for which latter a new specific 

 name will now be required, since the name brasiliensis must be retained 

 for the ^, now referred to Geranomyia. I therefore propose westwoodi 

 for the $ of Westwood's brasiliensis, and it will of course be the type 

 species of Limnobiorhynchus. 



The respective characters of the genera in question may be tabulated 

 thus : — 



A. Submarginal cell absent. (Antennae 12-jointecl ; long 



hairs on last two joints only ; pronotum distinctly 



produced over neck ; submarginal cell absent ; 



posterior cross vein at base of discal cell ; (itli 



vein very close to 5th for basal third of its length) Limnohiorhij nchus, 



Westw. 

 AA. Submarginal cell present.
