MEMOIBS OF THE QUEENSLAND MUSEUM. 



At first glance apparently belonging to T. imperialis, with which it would 

 be a.ssociated in my table, but antenna; decidedly shorter, thicker, and hairier, 

 the ninth and tenth joints no paler than the adjacent ones, apical joint of palpi 

 smaller, prothorax longer, elytra with a distinct costa on each, and the black 

 part at the base rounded posteriorly, instead of truncated. There are numerous 

 specimens of both species before me, and the differences noted are constant. On 

 both species the antenna^ are slightly thicker on the male than on the female. 

 On the male the flavous parts are much of the muzzle, a narrow space at apex 

 of prothorax, and more of its base (the basal portion advanced on the sides), 

 elytra (except for a small space at base and another at apex), parts of sterna, 

 much of under surface of abdomen, trochanters, and parts of coxa?. On the 

 male the extreme base of the head is about half the width across the eyes, on the 

 female it is about two-thirds. 



HETEROMASTIX PUSILLUS Boh. 



Five specimens from Mount Tambourine, and one from the Queensland 

 National Park, probably represent another variety of this species; they differ 

 from Sydney (the ty^pe locality) ones, in being smaller (2-2-75 mm.), and in 

 having the legs flavous, except that the femora on most of them are partly 

 infuscated. Another, from Brisbane, in the Queensland Museum, measuring 

 2 mm., has much of the prothorax infuscated. 



HETEROMASTIX PALLIPES Lea. 



A specimen from the National Park, in the Queensland Museum, appears 

 to belong to this species, but is slightly larger (4 mm.) than the type, the apical 

 joint of its antenna? is slightly stouter, and the two basal joints are dark on the 

 upper surface.
