Genus CHALCERINYS Perkins. 



Differs froui Echthrogonatopus Perkins in the metallic scutellum which is sculptured 

 nearly like the scutum. Marginal vein somewhat longer than wide, the stigmal a little longer 

 than it, the postmai'ginal hardly developed. The front between the eyes is wider than is the 

 ease with the genus named. Differs princii)ally from Echthrogonatopus in the relative lengths 

 •of the marginal and stigmal veins. Axillic sliglitly separated, the eyes sparsely hairy. 



The male has the first funicle .ioint longest, much longer than the pedicel, joint G next 

 longest to 1; the club solid. Also, the eyes are very widely separated. 



1. CHALCERINYS EXIMIA Perkins. Female; male. Genotype. 



Length, 0.7.5-1 mm. 



Metallic green, in places yellowish-brassy, the mesopleura and abdomen black, at most 

 slightly metallic, the antenna? testaceous, more or less sordid, the legs yellow except tips of tarsi. 

 Head densely and minutely sculptured and with evident traces of larger, very feeble punctures. 

 Caudal ocelli nearer to the eye margins than to one another. Thorax with very dense, minute 

 sculpture, the scutum and scutellum with similar and inconspicuous pale pubescence, the scutellum 

 smoother and more shining apically. Abdomen subtriangular. depressed. 



The male is the same but the antennae are long, the scape and funicle 1 distinctly 

 marked with black, the club slender and elongate, dark or largely so. 



Uahitaf: New South Wales — Sydney; (Queensland — Childers and Bundaberg. Parasitic 

 upon (loiiatopiis or an ally. 



Type: Query. 



Gexus SAKAX(.)TL'M Perkins. 



Rather slender and elongate; head (cephalic asi>ect) subelongate, the eyes moderate in 

 size and diverging apically, the front with dense, liiicroscopic sculpture and sometimes also 

 with very faint punctures. Ocelli in an isosceles triangle, the caudal ones near the eyes 

 and nearer to each other than to the cephalic one. Antenmse gradually clavate, the scape simple, 

 elongate, the proximal joints of funicle much narrower than the distal ones, the club small, 

 the i)edicel shorter than funicle 1. Maxillary palpi with a very long distal joint which is 

 subequal to the other three united. Labial palpi short, the middle joint extremely short. 

 Scutum with appressed, white pubescence, the scutellum with an erect tuft of bristles. Wings 

 infuscated at distal half or more, the submarginal vein much decurved before reaching the 

 marginal, the latter long, the stigmal rather short, the postmarginal little developed. Proximal 

 third of fore wing nearly naked; oblique hairless line present. Caudal legs long, slender. 

 Abdomen rather elongate, depressed, the ovipositor barely extruded. 



The male is not known. 



Ajiiiarently allied with Chfiloiiciinis Westunoil ililfering in the longer head, the elongate 

 form and the solid club. Compare Em^cmionclla.
