TIPULINJB. 287 



antennae normally not pectinate,* the nagellar 



joints always verticillate ; legs normally long 



and slender ; abdomen elongate, cylindrical, 



seldom widened towards or at the tip, unless 



due to the genitalia, which are generally 



large and complex in Tipula, less so in some 



other genera. Body colours mainly brownish 

 . and yellowish ; brighter in Pachyrhwa .... TIPULINI. 

 Legs of excessive length and slenderness, more so 

 than in the normal Tipulid forms ; the 2nd longi- 

 tudinal vein normally not forked (Dolichopeza), 

 if so, the anterior branch either obsolete or perpen- 

 dicular, thus making the rhomboid cell more or 

 less square ; nasus normally absent t DOLICIIOPEZIXI. 



It must be remembered that probably not one of the characters 

 herein employed is absolutely consistent throughout anv particular 

 section, the nearest approach to stability perhaps being the verti- 

 cillate nature of the flagelluin in TIPULIXI. 



Section CTENOPHOEINI. 



In addition to the genera with typically pectinate antennae in 

 the males, this section contains several others in which this 

 character is less fully developed or even entirely absent. Yet as 

 the group is represented in the East by practically one genus only 

 (Pselliophora), there is no need to enumerate the peculiarities of 

 the exotic forms. Apart from PsdliopTiora, a species of Prionota 

 has been described by Van der "VVulp from Java (P. ni;/riceps).^ 



All the species described by the older authors correctly belonging 

 to Pselliophora were placed in CtenopTiora, but they have now all 

 been satisfactorily referred to the former genus with one exception >. 

 C. xanihomelana, Walk., of which only^the female was originally 

 described, and the species not having been seen since, it is im- 

 possible to decide where it should be placed, the probability being 

 that it too is really a Pselliophora. It comes from " East India." 



As descriptive of the section, little can be added to the char- 

 acters given in the table above, so far as the Oriental genera are 

 concerned. The pectinate antennae in the males, the shorter, 

 stouter legs, the usually bright and sharply denned colours that 

 distinguish most of the species, make them easily recognisable. 



* Exceptions occur, but not in Eastern genera ; one, for example, Ozodicera, 

 comes from South America, which is practically a Tiputa with pectinate male 

 antennae. 



t Absent in Dolichopcza, but present iu frcamboneura and Mcgistocera, both 

 Oriental genera. 



J Prionota may be described briefly as having the appearance of a Pachyrkina 

 or Tipula, the venation of a Ctenophora, and antennae markedly serrate on the 

 lower side in both sexes, owing to the emargination of the base of each joint of 

 the flagelluin except the last one. P. iiignceps, Wulp, the only known species, 

 has an orange-yellow thorax, an abdomen yellowish on the basal half, blackish 

 on the apical half, with the legs yellowish, blackish at the joints. It is 16 mm. 

 iu length.
