AUSTEALIAX UYMESOPTEK.l CJIJLCIDOIDKA, Vll.—GUIAULT. G7 



I have frequently mistaken nienilicvs ut' this gninp for true eiieyrtids. Several genera 

 in the Taneostiguiinio resemble genera in this i;i"ii|. mmv much and there are seemingly inter- 

 grading forms. In the eases of species of Aphciiiius, Coccophagus and Pliyscus T have been 

 puzzled in regard tu wliieh group they should be classed. The Aplieliuina; frequently liave the 

 mesopleuruni entire, the antennaj are inserted below the middle of the face, the middle tibial 

 spur is frequently _ elongate (but usually slender), the mandibles are 2- or 3-deutate, the form 

 short and compact and the tarsi usually o-jointed. Four-jointed tarsi are not exeejitional in 

 the Encyrtidse. The wings here are frequently with an olilique hairless line, ring-joints are 

 visually absent, jumping is usual and the hosts are coccids. Alorco\er, the varietv of form 

 and markings is great. 



These characters certainly .-ipproach very closely those of the Kncyrtida^. 



A minute, wingless male of the Apheliniiii. with antenna: aliout as in Kictmoccnis, is 

 native to the jungle of North Queensland. 



Subfamily SIGNIPHf)RIN.-E. 



Gent-s SKiNIPHORA Ashmead. 



1. SIGNIPHORA AUSTRALIENSIS Ashmead. Female: male. 



I give the recent review of this species in my .\ Systematic Monogra]ph (jf the Ch.-ilcidoid 

 Hymenoptera of the .'^ulifaniily Signiphorina' ((iiraidt. I'.M:'.). 



" .Siiiinphiini (lustniliinsis Ashmead, llH)0,"pp. 40!l. 411). 



The original description of this species is exactly as follows: 



Female. — Length, 0.(30 mm. jSilneous black, the niesonot\im with ;i bronzy tinge, the 

 scutellum with a slight bluish tinge; legs black, a s]iot on knees ;ind tarsi white or yellowish 

 white, the anterior tibia) yellowish beneath ; wings fuscous with a hyaline band across the disk 

 from apex of the marginal vein. 



Type.— Cat. No. -1771, U.S.N.M. 



Eahitat. — Australia (Albert Koebele, collector). 



Host. — Ehynch. : Sp. not identified. 



By studying the types I am enabled to oll'er the following ;idditional descrijitive details: 

 Like nigra but ditl'ering colorationally in that the head and thorax are metallic to some extent, 

 fhe vertex and mesonotum distinctly metallic green (hut not in balsam mounts), the latter 

 finel.y transversely lined; body finely polygonally .sculptured, including the abdomen (the 

 sculpturing not distinct in balsam mounts) ; the fore wings dift'er ;is described — they are 

 embrowned throughout, but somewhat dist:id of the middle there is a broad clear band, 

 subcrescentic in shape and touching the costal margin at the apex of the stignial vein. This 

 area is broader at the caudal margin than at the cejihalic one, barely reaching the latter; 

 the stigmal vein differs in that it is like a short conical prolongation bending off slightly from 

 the marginal; thus it is short and much broader at its |>oint of origin than is the case wdth 

 that of nigra. Like nigra, there is also a clear area proxiniad, but this is somewh:it more 

 prominent with this species. (See beyond.) The nuile is like the fennile. 



The species has imt been mentioned ;igain in the liter:iture; it is \ :iri.-ilil(> ;is will be 

 ■shown later. 



I have studied the follow'ing sjiecimens: The tag-mounted types now renuninted in 

 sylol-balsam ; these were and are labeled ' Signiphora aastrulienHs Ashmead, female. Type 

 No. 4771, U.S.N. M. Australia. Koebele, 1-.' The type consists of three females. Also a 

 slide from the collections of the United States Dejiartment of Agriculture. Washington, District 

 of Columbia, bearing 2 males and 12 females and labeled ' lS4it. Ac/inthococcid on Kuealiipliis. 

 Gosford, N,S.W., Nov. 1S99, A. Koebele.' These specimens v.aried considerably in the 

 fumation of the fore wing and in the length of the marginal fringes. In all of them the 

 latter were distinctly shorter thiiri in the tyjie specimens, wliile the majority of the specimens
