ARRIIENOPHAGOIDEA new genus. 



1. ARRHENOPHAGOIDEA COLORIPES new species. Female. Genotype. 



Length, O.s.j nun. Ditiers Ircmi the gi'imtype of Ariliinopliaj/as Aurivillius in bearing 

 5-joiuted tarsi. The antenna:' are 5 jointed, ((uite .-is in Arrlunophngux — scape, pedicel and 

 3-jointed club, the proximal two joints of the Latter transverse linear, the third joint four 

 times their united length. Differs from Hhopoidciis Howard in the shorter form, the lack of 

 an oblique hairless line on the fore wing and in the short, thick antennae. The species is 

 similar in every respect to Arrhenophacius chionaspidis Aurivillius excepting that the legs are 

 all concolorous except the knees, tips of tibiio, tarsi, the intermediate legs and the cephalic 

 tibiie which are yellowish. Also the middle tibial spur is stouter. No yellow on body. 



Hahitat: Ingham, Queensland. February 17. 191o. 



Type: No. EyS071, Queensland Museum, Brisbane, the single female on a slide. 



The frons is broad, no substigmal spot but a marginal vein is indicated by a slight knot 

 or swelling, w-hich gives off a short, acute stigmal vein. The venation does not reach the costal 

 wing margin. Middle tibial spur distinctly siroUcii or thick as normal. Hairless line of fore 

 wing apparently absent. Type re-examined. 



A second species has been seen either from southern or western Queensland Ijut unfortu- 

 nately it was mislaid and I could not describe it from the parts mounted on a slide. The hind 

 tibia; were white, the fore wing with a more or less obscure hairless line and snbstigmal spot.

 1. ARRHENOPHAGUS CHIONASPIDIS Aurivillius. 



According to Schmidekneokt (U109) Ashmead records this widely distributed species 

 from Australia. I give its principal characteristics. 



Tarsi 4-jointed; antennse as in Arrhenophagoidca ; fori' wings without an oblique hairless 

 line, the marginal, postmarginal and stigmal veins absent ; marginal veiu represented by a 

 circular fumated spot. Shining black, the disk of abdomen with some yellowish dorsad. Antennsu 

 honey yellow, also the legs but dorsal aspect of caudal legs blackish and most of cephalic femur. 

 A small yellow area just eephalad of tegula; a nmderately broad, yellow fascia on upper face 

 (on or near caudal margin of vertex). Mesothorax scaly but the seutellum finely, delicately 

 longitudinally striate. Wings hyaline. Mandibles acute. Tibial sjiurs all small. Widely 

 distributed — Europe. Asia, North America and Australia. 1 have seen si)eeiniens from .lava and 

 Porto Rico (West Indies). Parasitic upon various coccidie of commercial importance.
