290 MEMOIRS OF THE QUEENSLAND MUSEUM. 



5. GROTIUSELLA THOREAUINI new species. 

 Female: — Length, 1.30 mm. Hind tibial spurs short, unequal. 



Dark metallic green, the wings hyaline, the legs white, except the dusky caudal femora 

 centrally, the caudal tibia; just below knees for half way to apex and middle tibise just below 

 knee at proximal fourth. Head pale whitish except occiput and center of vertex broadly. 

 Antenna) yellowish, the scape and pedicel whitish, the pedicel dusky (or metallic?) above. 

 Mandibles with two outer acute longer teeth, then obliquely truncate and with four minute 

 comblike teeth. Body marked with golden yellow as follows: — A rather large spot on each 

 side of meson of neck of pronotum; an oblique line down scutum on each side (distad along 

 mesal margins of the axill^, the latter cephalad of the seutellum) like parapsidal furrows but 

 constricted at about cephalic fourth; all margins of seutellum except at meson of base; 

 lateral and caudal margins of axilUTi, the caudal yellow joining the long oblique streak on 

 seutiun at its apex; mesopostseutellmn ; a stripe on abdomen just out from base, bluntly 

 incised at meson of cephalic margin and at each lateral running more narrowly to base; two 

 cross-stripes distad of this both broadly interrupted along the meson; a broader, complete 

 stripe distad of these and a little distad of middle; a similar stripe next but broadly inter- 

 rupted at meson and a little shortened laterad; then a complete stripe of same length and 

 still some distance from apex. Propodeum glabrous at meson, with a median carina and no 

 others; scaly laterad. Thorax densely scaly, the pubescence very sparse. Antennal cluk 

 apparently 2-jointed but closer scrutiny shows that no articulation is present; ring-joint 

 extremely short; funicle 1 longest, subquadrate, larger than the globular pedicel, the following 

 joints distinctly wider than long, each widening a little in succession. 



Coloured like species of Gyrolasella for which I mistook it. 



Respectfully dedicated to Henry David Thoreau. 



Described from one female taken by sweeping bushes, October 10, 1913 (G. F. HiU).

6. GROTIUSELLA PEARSONI new species. 



Female: — Length, 1.35 mm. 



Very similar to hyatti but tlie cheeks are green and tlie stripe down the face alono- the 

 eyes is first interrupted dorsad of middle and for tlie second time, a little ventrad of middle, 

 some distance dorsad of ventral end of the eye; the legs are wholly lemon yellow, the aiiex of 

 postscutellum is metallic green rather broadly, the whole of base of seutellum is metallic green; 

 the venter and sides of abdomen are deep golden yellow; moreover, the broken cross-stripes of 

 abdomen are rather spots (counted as strii)es, there are init fi\-e— tlic first and last complete 

 stripes, the fourth consisting of two round marginal spots, the third a rather broad stripe 

 interrupted at meson, the second two wider than long marginal spots) ; first stripe rather 

 broad, incised at meson of cephalic margin. Propodeum glabrous except laterad of spiracle. 

 Otlierwise as in hyatti. 



From one fem.ale captured in the same place as hyatti, described below, on May 9, 1914. 

 Habitat: Chindera (Tweed Kiver), New South Wales.
