pointed processes can be observed, it is very probable, that they are used 

 for penetrating the two membranes which close the larval tunnel. Behind 

 the head the funnel-like protruding thoracical stigmata can be seen. Shortly 

 before emergence of the imago the wing sheaths and legs are coloured black, 

 the thorax brown and the abdomen red. For a description of the imago can 

 be referred to the preceding paper. 



Parasite (Chalcidid), Plate XII, fig. 6 and 7.- 



In one case the pupa of this parasite was found in a gall near the empty 

 pupal skin of the gall midge; in another case a white, rather large egg of a 

 parasite was found near a pupa. 



These facts give some evidence as to the character of the parasite, which 

 very likely attacks the pupa. 



The chalcidid parasite was bred from the galls several times and is the 

 most effectual ennemy of Trishormomya. 



A description of both male and female follows hereunder. 



The name of this, very likely new species shall be mentioned later. 



Male. (fig. 6). 



Length 3 to 3,5 m.M. Head metallic b/ight green, eyes brownish red 

 mouth parts pale brown; antennae: scapus yellow, other parts brown; ocelli 

 brownish black or black. Antennae consisting of scapus, pedicellus, 

 anellus and 8 funicular joints, the last one large and consisting out of three 

 parts. 



Thorax metallic green with honeycomblike sculpture; mesopleurae black. 

 Legs pale yellow (nearly white) excepting two thirds basal of 'the posterior 

 coxae which are metallic green with blue iridescence, canaliculate. 



White hairs are scattered all over the thorax and are also seen on the 

 posterior coxae. Wings hyaline, pubescent. 



Abdomen: first segment entirely and second segment partly yellow, rest 

 of second and other segments black and dark brown with faint greenish 

 iridescence. 



Female, (fig. 7). 



Size 3,5 to 4 m.M., terebra 3 m.M. Colour like the male, excepting the 

 abdomen on which the black colour is limited to the dorsal area of the apical 

 half. Terebra piceous. 



In another case other smaller parasitical larvae were found but this 

 species has not been bred by me.
