P KRT L A M P O LTD® 3 new genus. 
Female: — Like Epiperilampus Girault but the antennas only 12-jointed, there being but 
five joints in the funicle, the club 3-jointed ; flagellum elavate. Also the axilla) are separated a 
short distance, the parapsidal furrows ending at middle of cephalic margin of each axilla. 
Scutum with a shallow median groove, the scutellum large, ovate, longer than usual but not 
extending over all of propodeum; abdomen large, globular, somewhat as in the Cynipidas, the 
ovipositor very short, near apex. Thorax impunetate. Hind tibial spurs single. Mandibles 
bidem ate, the inner tooth broadly truncate. Axilla) very long, triangular. Scutellum with a 
short median groove at base. In Epiperilampus, the axilla) are barely separated inwardly. 
Male: — Not known. 
Type: The following species. 
1. PERILAMPOIDES BICOLOR new species. 
Female: — Length, 3.75 mm. 
Bright orange yellow, the face and mesal portion of pronotum, scutum a little at meson 
ceplialad, propodemn and abdomen jet black; also mesoventer tnesad and the vertex; antennas 
and legs pale yellow; wings hyaline, the submarginal vein black, the others colorless, a rounded 
sooty spot mi blade of fore wing just caudad of the apex of submarginal vein. Thorax finely 
she greened (raised dots). Distal funicle joint largest, about as long as the pedicel, cup-shaped 
but wider than long; second club joint shortest. Antenna) suffused with dusky. Hind tibia 
more or less dusky. 
Described from two females reared from pupa) filling the entire cavity of small round 
isolated galls on the foliage of Eucalyptus in forest early in August, 1913 (A. P. Dodd). 
Habitat: Nelson (Cairns), Queensland. 
Type: No. Hy 195 i, Queensland Museum, one of the above specimens on a tag, the hind 
leg and a head on a slide. 
This genus is evidently a true gall-maker allied as is Epiperilampus with Mayr’s three 
gall-making genera. Epiperilampus, indeed, seems to me to be the same as Mayr’s 
Trichilog aster but I cannot tell because the original description of that genus is not available 
and there may be differences in the antenna>. These gall-making genera seem true perilampids 
in spite of the long scutellum in some of thorn and the longer, depressed abdomen. They have 
the habitus, in some cases, of the Encyrtid tribe Taueostigmini but there are no encyrtid 
characters. They are allied with the Cleonymida) and Eurytomidm.
