and especially of new genera, has been of very infrequent occurrence. 

 Species have been received from all parts of the world, owing to the 

 extraordinary and world-wide development of interest in scale insects, 

 which are the principal hosts of the Aphelininse, yet nearly all of the 

 forms thus received have been species already described, which have been 

 carried with their hosts upon live plants to many different regions. It is, 

 therefore, interesting to discover a new genus, even from a country 

 like Chile, whose parasitic Hymenoptera are so little known. A most 

 interesting feature of the discovery is that the new genus was reared from 

 Aspidiotus hedercp. (nerii) together with three of the cosmopolitan forms, 

 namely, Aspidiotiphagus citrinus {(Zxd^s)\ Coccophagus imtnacuhitus, How., 

 and Prospalta aurantii, How. The writer is indebted to Mr. Edwyn C. 

 Reed, of Rancagua, Chile, for this sending, as well as for many other 



favours. 



Aphytis — New Genus. 



Female. — Resembles Aphelinus in the oblique hairless line extending 

 from the stigmal vein transversely to base of wing. It differs principally 

 from Aphelinus in the antennse, which are only 5-jointed, the first 

 ring-joint apparently being absent. The pedicel is nearly cylindrical ; the 

 the first funicle joint cubical; the second funicle joint long = oval, wider 

 than the first and more than twice as long ; club long, elliptical, longer 

 than pedicel and funicle together. The mesonotal sclerites resemble those 

 of Aphelinus, but the ovipositor is exserted to about one-third the length of 

 the abdomen, as with Centrodora ; hind thighs somewhat swollen; stigmal 

 vein is short and knobbed and the post-marginal vein is absent ; the 

 mandibles are tridentate ; the ocelli large and placed in the form of 

 an oblique angled triangle. 



Aphytis Chilensis, n. sp. 



Female. — Length to tip of ovipositor 0.94 mm.; expanse 1.8 mm.; 

 greatest width of fore wing 0.18 mm. General colour pale yellow, with 

 slight dusky tinge on the dorsum of the thorax ; the lateral margins of the 

 abdominal segments with dusky transverse stripes ; antennae fuscous ; 

 wings with a faint dusky cloud below stigmal vein. 



Described from i female, reared by Edwyn C Reed, from Aspidiotus 

 hederce, on ivy (presumably Hedera helix), Rancagua, Chile.
