Paracorotoca; a considerable quantity in the imago- 

 Term itomimus and a moderately large quantity in the 

 imago Paracorotoca. 



(6) The exudatory structures for producing an agreeable 

 scent or for the passage of fluid licked up by the termites 

 vary in the different forms. In the larva Paracorotoca 

 they consist of paired lateral outgrowths of certain abdominal 

 segments. In imago Paracorotoca there are (1) abilobed, 

 median dorsal outgrowth from the front end of prothorax ; 

 (2) median swelling of dorsal surface of abdominal segment 

 VIII; (3) paired, backwardly directed swellings from the 

 posterior surface of metathorax. Some similar swellings 

 occur in Termitomimus, but (2) is not obviously present 

 and (3) are less strongly developed ; Tragardh believes that 

 fluid also exudes from the ventral, lateral and posterior parts 

 of the rounded, hinder portion of the body. 



For the present it cannot be stated whether the inter- 

 segmental glands and eversible anal organ of the larva and 

 the tergal glands of the imago are adaptations to a termito- 

 philous life. 



(7) In the female imago Paracorotoca there is a long 

 convoluted vagina into which open two thin-walled oviducts 

 bearing a number of ovarian tubes. The ovarian tubes are 

 exceptionally short both in Paracorotoca and Termito- 

 mimus, each tube consisting of about two pairs of elements 

 in the former and usually of only one pair in the latter. The 

 ova grow to a great size and are richly supplied with large 

 yolk-globules. From analogy with Corotoca, the absence 

 of any egg-shell and the strong muscular nature of the 

 vagina, it may be concluded that Paracorotoca is vivi- 

 parous. In the male two extremely large follicular testes 

 communicate by means of two short, narrow vasa deferentia 

 with a median, straight, muscular ejaculatory duct ; opening 

 into these vasa deferentia are two accessory glands and two 

 large, branched vesiculre seminales. 



Associated Avith the fact that there is no obvious bursa 

 copulatiix in the female the virgal tube ends in a small.
