294 r - A. L. SMITS V. PATRGST, A MINUTE HYMENOPTERON 



Forewing long, submarginal and marginal veins subequal 

 in length ; stigmal short, situated at half the wing length 

 and exactly opposite to the termination of thickening of 

 hinder margin of wing, this being also the widest point of 

 the wing ; cilia of wing surface rather sparse, a clear rounded 

 space immediately below the stigma ; marginal vein bristly 

 (6 to 7 bristles); marginal cilia ven* long, longer than wing 

 width, those on costal margin just beyond stigma nearly as 

 long as those on hind margin. Hindwings with long marginal 

 cilia and but one row of discal cilia on outer third. 



Legs somewhat slender, terminated by 5-jointed tarsi with 

 enlarged pulvillus ; femora not thickened ; tibiae spinose, 

 spur of middle tibiae very slender, as long as the first 

 tarsal joint. 



Head nigrescent ; vertex and frons bright flavous, ocelli 

 brillanti)' red ; eyes dark ; temples rufescent. Antennae 

 nigrescent, basali)' rufescent. Thorax fuscous, mesoscutum 

 and scutellum pale flavous. Wings with marginal vein fuscous 

 and broad fuscous band extending directly across wing from 

 marginal vein as a base. Abdomen, as far as the spiracles, 

 parti)' brillanti)' dark violet, towards the apex nigrescent. 

 Legs pale with fuscous markings. 



This very distinct species is certainly related to a remark- 

 able degree with Aspidiotiphagus citrinus Craw., the only 

 representant of the genus Aspidiotiphagus, but differs, beyond 

 its colouration, in man)' salient structural characters. 



HOWARD gives a description of Aspidiotiphagus citrinus 

 in „ Insect Life", bulletin of the U. S. Departement of Agri- 

 culture Vol. VI, No. 3, Washington 1894, which is reported 

 to have been bred from various scale-insects. It was reared 

 in the U. S. from Aspidiotus aurantii Maskell, var. citrinus, 

 from Diaspis bromeliae KERN, on Ananasa sativa and from 

 Aspidiotus ficus, and in Italy it was bred from an Aspidiotus 

 on Acacia longifolia and from Diaspis rosae. 



In the in glycerin-gelatin mounted specimens the curious 

 internal structure of the Aphelininae, which is called by 

 BUGNION in his „Développement, etc., de l'Encyrtus fusci- 

 collis", the ,,mesophragma", is seen to extend far back 

 into the abdomen, much farther than with BuGNlON's
