suture being complete; the sclerite is covered with rather sparse 

 long hairs (see pi. 48, fig. 58) ; the pleurite bears three appendages, of 

 which the outermost is a long slender hook, incurved near its apex 

 and here strongly chitinizcd ; this appendage is clothed with scattered 

 hairs along its ventral and outer edge and with numerous zigzag 

 teeth on the inner dorsal margin (in some specimens the margin is 

 quite smooth and straight) ; the tips of these long hooks in a position 

 of rest, decussate. Inside of this long hook are two shorter append- 

 ages, the outer being the shortest and smallest, oval, pale, the tip 

 somewhat expanded, the entire appendage with numerous long pale 

 hahs (see pi. 48, fig. 59) ; the innermost appendage is a long, slender, 

 compressed arm with an enlarged compressed head, the cephalic or 

 dorsal side heavily chitinized, black, the remainder pale. 9th 

 sternite long and slender, its tip projecting far beyond the remainder 

 of the hypopygium in a long point (see pi. 48, fig. 60). 



Doctor Enderlein has erected the genus Tipulodina for this insect 

 but there seems to be no sufficient reason for retaining this name. 

 In the first place, the name was proposed under the mistaken suppo- 

 sition that the msect was a Limjiobine form. Secondly, none of the 

 characters of the genus seem to differ from those of other genera, 

 although, in some respects, the insect occupies a rather intermediate 

 position. The straight R^ and narrow cell 2nd A are characters 

 found in many species of Tipula; the short Rs is the common char- 

 acter of PacliyrUna; the shape of the cells in the median field of the 

 wing are those of Ctenacroscelis, etc. The powerful male hypopygium 

 and the unusual leg-coloration may offer generic differences, but until 

 the related forms (venusta Walker, inordinans Walker, cinctipes 

 de Meijere, gracillima Brunetti, patricia Brunetti, and others) are 

 studied it would be decidedly premature to recognize the genus 

 Tipulodina. 



The rather curious pupa of Tipula pedata has been described as 

 foUows by de Meijere:^ The remarkable pupa of T. ptedata found in a 

 pot of stagnant water with water-plants (Salatiga, Java, January, 

 van Leeuwen). The pupal sldn sent to me is 34 mm. long and 4 mm. 

 broad, of a blackish brown color. The very long and slender, seta- 

 ceous, arcuated breathing-horns are very remarkable; they measure 

 11 mm. in length, are of a blackish brown color, only the extreme 

 tip which is sliglitl}' expanded is yellow; elsewhere they are almost 

 uniform in diameter throughout except toward the base, where they 

 are a very httle enlarged. The dorsal abdominal segments bear a 

 cross-row of tooth-like projections before the caudal margin of each; 

 the ventral segments are quite similar, but here the median teeth on 

 the hmder segments are longer and with a pair of shoiter appendages 

 before them. The tip of the abdomen likewise presents a numl/cr
