230 MEMO I EH OF THE QUEENSLAND MUSEUM. 



Of four males before me three have most of the abdomen infuscated, 

 but on the other, and on four females, it is no darker than the rest of the under 

 surface. The medio-lateral tooth on the prothorax ol the male is somewhat 

 larger but less acute than on M. quadnvittatits; the male is unmistakably a 

 Macrofjonus, but I am unable to point out how tli" female may be distinguished 

 from Macroiema.

 LANGURIA ALBERTISI Hr.r. 



L. vulgaris Har. 



L. vandepolli Fowler. 



L. anstralis Mael. 

 The species of Languria so abundant in the Cairns district (it occurs also 

 at Bowen, Cooktown, and Melville Island, and there are specimens in the South 

 Australian Museum from the Madang district of New Guinea, and from Aru) 

 has the head and prothorax red, and elytra black, with a bluish or purplish gloss; 

 the antenna? and legs are black and the mesosternum, metasternum, and abdomen 

 are black or deeply infuscated ; this is the most common form, and has been 

 named vulgaris, vandepolli, and australis. On 28 specimens before me the under 

 surface is red, and the legs and antenna? partly red, agreeing with the form 

 named albertisi ; the differences are probably due to immaturity, as the two forms 

 occur freely together, and there are others before me in which the normally 

 black parts are infuscated in varying degrees. The eighth joint of the antennae 

 is slightly larger than the seventh, but distinctly smaller than the ninth ; on the 

 males being produced slightly to one side, it might fairly be regarded as part of 

 the club, but on the females it evidently could not be so regarded ; in albertisi 

 the club was described as three-jointed, and in viiUjaris as four- jointed, but I 

 believe these names to belong to but one species. Blackburn has already noted 

 vandepolli as a synonym of vulgaris, and australis has now to be noted as another. 

 The size ranges 2-4-5 mm. 



In Wytsman's Genera Insectorum, Fasc. 78, in which the Langurides are 

 dealt with by Fowler, albertisi was referred to Stenodastus, vulgaris to (■mno- 

 languria, vandepolli to Anadastus, and australis was overlooked. Of the other 

 species recorded from Australia L. militaris has the suture reddish (of 121 

 specimens of albertisi before me not cue has the suture reddish), and L. picea 

 has the head and prothorax nio;roi)iceous (several specimens of albertisi have the 

 head infuscated at base). 



EPISCAPHULA OP AC A Crotch. 



A remarkably distinct species, the curved red mark on each shoulder is 

 soDietimes entire, but is usually broken up into two pai'ts; on one specimen the 

 markings are reduced to a dull si)ot on the shoulder, and another near apex of 

 each elytron, the spots so dark that, to the naked eye, the upper surface appears 

 entirely black. Specimens before me are all from Queensland: Cairns, Port 

 Curtis, Bowen, and Bluff.
