catolaccus asphondyliae Masi (n Palearctic species) was figured by Parker (12) and the egg of Heterolaccus hWllteri by Pierce Cushman and Hood (13)

HISTORY OF THE GENUS CATOIACCUS

Catolaccus was described from Sweden in 1878 by Thomson (15) with one included species caI)ifena Thoms This species canllot be placed with much exactitude from Thomsons characterization alone and most authors who have treated the genus subs(quently havc stat(d that they had not seen a specimen of this genotype speci(s However the characterizations of Catolaccus given by Howard in 1886 (8) and Cresson in 1887 (6) ar( both in ngreem(nt with tht chaLllcters of tlw genotyp(

Ashmead in 1893 (1) 1894 (2) 1896 (3) and 1904 (4) how(ytr defintd OatolacClls and used the generic llltme in a rather ambiguous wny He referred to it an assortment of species that can hardly be considered congeneric and he pvidently misinterpreted Thomsons characterization of the genus All th( species Aslmleac described in (atolaccus have subsequently been transferred to other genern Crawford in 1908 (5) although stating lllfit the current usag( or tJl( generic name CatolaCCU8 was not satisfactory keyed out Hie North American specie) that he COIlsidl(CCl to b(lollg in this genus as ric-shyfined by Ashmead All thesl spteilS ha( Subslquentl~T Iwen transshyfeITcd to oOW1 genera Rehmildtknecht in 1909 (14) attempted to combine Thomsons originnl (halllet(rization of Catoacclls and Ashshym(ads l(charact(rization of it with the result that tl]( genus b(came all but unlecognizabk

In 1913 KUI(LjumoY (9) published thl r(sults of his cardul study of nearly all till typlS of th( gtllotype speCils of the Ptllolllalina( He wns able to (xamilH th( pincipal Europenn eollections as well as thosl in the U S Nationul ~fus(um H( saw Thomsons type of cavigena stat(d that it was UIl samp splci(s as th( much bcttpr known Pteromai1ls aiel Ratz and COIT(Ctly placed th( gtllUS CatolacC1lR ill a ker to the genem of til( Ptlrol11alinne Hl stat(d flatly that lIAshm(ads (~lnssifiention of the subfnmily Pt(lomnlinnl is a st(p baekwalds This is n llI-justifi(d conclusion 1 an (xnmple the genus lVeocatolaccultl Ashmend whieh ]1( d(scribed tiS bling dosely related to (atolacClls aCtually falls in till trilw ~[rtnst(llini lIOt til( Pt(lOllllliilli ill which (atoacclls is pln(((1
