median segments of abdomen conspicuously impressed along 

 the middle. 



There are in the South Australian Museum the type 

 female and a co-type male of botcrkei,^ 20 ) and these agree per- 

 fectly with Janson's description of yorkiana; the latter name 

 has precedence. 



Lomaptera pygm^ea, Kraatz. 



A few years ago Mr. Hacker took numerous specimens of 

 a small species of Lomaptera at the Coen River. Some of 

 these were compared and agreed with specimens in the Macleay 

 Museum from New Guinea, standing under the name of 

 pygmcza. Recently Mr. W. D. Dodd took six specimens of 

 the species at the Coen River, and these agree with the original 

 description, except that the size is smaller (15^-19 mm. as 

 against 19-21 mm.) and that the entire legs, instead of appar- 

 ently the femora only, are of metallic-red. 



In general appearance it is like pulchripes, except that 

 it is smaller and more metallic, but the clypeus is more deeply 

 cleft and the scutellar lobe is rounded at the tip, concealing 

 the scutellum. 



Lomaptera avallisiana, Thorns. 



This species was originally recorded as from Wallis 

 Island, but Wallace records it from Cape York from a speci- 

 men in Major Parry's collection. Janson compared it with 

 yorkiana, from which he stated it differs in the prothorax 

 regularly rounded at the sides from the base. 



I have seen several species labelled as wallsiana and 

 waUisiana, but they usually belonged to yorkiana. 



Lomaptera pulchripes, Thorns. 



A common insect in Northern Queensland, although in 

 Masters' Catalogue only recorded from Fitzroy Island. 



The male has a rather wide depression along the middle 

 of the second and third abdominal segments, but traceable 

 on to the preceding and following ones. A male in the 

 National Museum is larger (25 mm.) and rather broader than 

 usual, and has the pygidium of a beautiful golden-red. 

 Another male in the National Museum (from the Endeavour 

 River) is of a most beautiful golden-green, both above 

 and below, with the legs and pygidium of a beautiful purplish- 

 bronze. Each of its front tibiae has the two terminal teeth 

 ■of normal length, but the following one (in the middle of the 

 outer edge) is greatly reduced in size, appearing little more 

 than a slight swelling. 



(20) It is from these that the figures of the tibige were drawn.
