( clxii ) 



produced forwards into a longisli horn — this may be analagous 

 to the furca in the Lepidoptera. 



Dexiosoma caninum 



has very insignificant arniatiire : tlie tegumen is merely a 

 small horn-like iincal projection, on each side of which is a 

 similar-shaped sclerite somewhat larger, whilst the ventral 

 pads are much reduced in size. 



Panzeria rudis 



follows the same line of structure : the tegumen is largish 

 and finely cuneate, below it are a pair of large, prominent, 

 somewhat cone-shaped sclerites ; the tedceagal ring is furnished 

 with a pair of cm-ved apophyses, rounded at the apex at 

 its upper margin, and a pair of tusk-like apophyses, the small 

 axlceagus protruding between the two ; the ventral pads on 

 the terminal abdominal somite are three in number, one on 

 the venter and one on each side of it. they are small but well 

 developed. 



Eudoromyia magn korn is 



differs in some particulars ; the largish tegumen has the 

 long uncal projection terminating in a line hook, below it 

 are a pair of large cheeks with an arm-like process bent round 

 their fore edge ; the sedoeagal ring is of moderate size, and the 

 ventral pads are fairly prominent. 



Fliorocera caesifrons 



has a different type of armature ; the tegumen is large, 

 being a very prominent hollowed pallate process curved into 

 a rounded apex ; directly below it at the hinder edge are two 

 somewhat rounded cheeks with a fine digitate process emanat- 

 ing from them, whilst the jedoeagal ring has apophyses of 

 quite small dimensions. 



Sarcophaga coniaria. 



In this genus the external organs consist of little more 

 than the tegumen, which in its uncal apophysis is semi- 

 cylindrical, the front apex being excised and tapered off into 

 two cuneate apices; immediately below the tegumen are
