178 THE ENTOMOLOGIST. 



1. Zagrammosomoides fasciatus, sp. n. (normal position). 



Female. — Length about from 2-2-50 mm. General colour flavous, 

 the eyes red, the wings hyaline, the appendages and venation con- 

 colorous. Conspicuously marked with black as follows : in the dorsal 

 aspect the abdomen is banded across the posterior margins of the 

 segments commencing at base, there being six transverse stripes 

 which lengthen (widen) distad, or else the middle ones are broader.* 

 The propodeum is black ; also the pronotum cephalad in the dorsal 

 aspect on each side of the median line, appearing like two large 

 cuneate spots ; a large ovate spot in the centre of the mesoscutellum, 

 an ovate spot on each side of (not upon) the scutum, in the cephalic 

 angle of each axilla, and a smaller spot at the caudo-lateral angle of 

 the pronotum. Cephalad in the disk, the scutum is distinctly stained 

 except along the median line ; each parapside is similarly stained, and 

 also the vertex may be so, here the stained area projecting into the 

 face (cephalic aspect) like wedges on each side. The ocelli are in a 

 nearly straight line across the vertex. The antennae are suffused 

 with dusky, as are also the femora of the legs, more or less. The 

 proximal club-joint is nearly half as long as the entire club. Whole 

 body finely, polygonally reticulated, the vertex and face with more or 

 less obscure umbilicate punctures. (From many specimens, f-inch 

 objective, 1-incb optic, Bausch and Lomb.) 



Male. — Somewhat smaller ; the same, but the dark areas on the 

 cephalic part of the scutum usually black and nearly coalesced ; the 

 abdomen bears only five transverse stripes which lengthen (become 

 thicker) caudad, the second concaved at the meson, the fifth twice 

 longer than the fourth, none of the distal four stripes with parallel 

 margins. (From numerous specimens, similarly magnified.) 



Described at first from ten males and sixty-two females 

 reared from a single globular green gall from the foliage of 

 bloodwood gum (forest), Nelson, North Queensland. The gall 

 measured 1*2 cm. diameter, and was blushed with pink. It was 

 obtained on August 22nd, 1912. When cut into halves the 

 naked pupre of this eulophid were exposed, arranged in a fiat 

 layer circularly disposed about a common line-like centre. 

 Emergence commenced on August 23rd, and became general 

 three days later, when the whole periphery of the gall became 

 punctured with the minute exit-holes, as though it had been 

 used some time for a pin-cushion. When approaching full 

 development the white pupse first show the black markings, the 

 yellow appearing last. 



Subsequently reared in enormous numbers from similar galls 

 measuring 1*6 cm., the first two weeks in September. 



Habitat. — Australia : Nelson (Cairns), Queensland. 



Types. — No. Hy/1169, Queensland Museum, Brisbane; two 

 males, two females, mounted on card points, two pins. 



This eulophid appears to be a true gall-making species. 



* The penultimate stripe prolonged caudad at meson, the ultimate thin, 

 the first concaved along the cephalic margin. There is some variation in 

 these stripes.
