the Jig -insects of Ceylon. 379 



The insects described and figured by Dr. Coquerel are 

 four in number, three wingless and one winged individuals. 

 The winged Chalcis explorator, Coquerel, now proves to 

 be a female Sycophaga : the Sycocrypta cceca, Coq., is 

 the male of a species of Blastophaga : the Apoerypta 

 paradoxa, Coq., is the male of a Sycophaga, of which 

 the female is unquestionably the winged Chalcis ex- 

 plorator of Coquerel, agreeing with the female insect 

 figured by me in our ' Transactions ' (1882, Plate II., 

 fig- 2). 



The remaining wingless insect figured by Dr. Coquerel 

 under the name of Apoerypta perplexa (op. cit., p. 369, 

 PI. X., fig. 2) is smaller than A. paradoxa, "L. 4 a4|mil.," 

 being 3 to 3^- mm. long, and differs from the latter insect 

 (cf. Trans. Ent. Soc. Lond., 1882, PI. II., fig. 1) in several 

 important respects. It is comparatively much narrower, 

 more cylindrical, with short mandibles acute at the tip 

 but destitute of teeth on the inner margin ; the antennae 

 composed of three joints, of which the basal joint is not 

 dilated into a large oval plate ; the clypeus forms an 

 acute point between the insertion of the antennae. " La 

 levre inferieure presente une languette plus allongee que 

 dans 1' A. paradoxa. " The abdomen is not quite so long as 

 the thoracic segments, as wide as the posterior part of the 

 thorax at its base, and gradually dilated till it becomes 

 twice as broad as the head, " Ici les deux grandes trachees 

 laterales ne viennent pas aboutir a des lames membra- 

 neuses (as in A. paradoxa or Sycophaga, male) ; elles se 

 rendent a d'enormes stigmates qui sont situes sur la face 

 dorsale de l'avant-dernier anneau. Ces stigmates sont 

 munis, a leur partie superieure d'un bourrelet saillant. 

 L'extremite de P abdomen est muni d'une tariere semblable 

 a celle de l'espece precedente," and which "je suppose 

 etre la tariere qui sert a l'insecte a introduire les ceufs 

 dans les drupes dont est garni l'interieur des fruits." 



Among the numerous species of fig-insects forwarded 

 to me by Mr. Stainforth Green and Dr. Thwaites from 

 Ceylon, I found, as parasites upon Ficus glomerata, 

 specimens of what appear to me to be identical with the 

 three wingless insects figured and described by Dr. 

 Coquerel. And it is to the Apoerypta perplexa that I 

 now desire to call the attention of our Society ; and 

 which, with its various details, I have represented in 

 Plate XVI., figs. 2 — Zg. On comparing these with the 

 details of the male Sycophaga, given in Trans. Ent. Soc.
