COLEOPTEEA.—LEA. 207 



Hah. — Queensland: National Park in December (H. Hacker). — Type 

 (unique), C/2301 in Queensland Museum. 



The sides of the prothorax are dilated and thickened anteriorly, but not 

 abruptly as in E. pusillus and allied species, so that in my table it would be 

 associated Avith H. victonensis, H. pauxillus, and H. simplex, from each of which 

 it is distinguished by its minute size. The tenth joint of the antennae is slightly 

 thicker than the ninth, but the difference is very slight, and not noticeable from 

 .several directions. 



LAIUS FLAVONOTATUS Lea. 

 Specimens of this curious little species were taken by Mr. Hacker on 

 mangroves, at Sandgate, in September. 



BALANOPHORUS SCAPULATUS Fairm. 

 Several specimens, sexes, of this species from the Queensland National 

 Park, and some females from the Richmond River and Dorrigo (New South 

 Wales), have most of the head of a deep shining black, the tarsi and apical 

 parts of middle and hind tibiaj more or less infuseated. 



CARPHURUS LONGUS Lea. 

 C. atricapillis Lea, var. 



Numerous specimens, all females, from the Cairns district, convince me 

 that C. atricapillis should be regarded as one of many varieties of C. longus, and 

 as the latter name was the first used it must be recognised as the typical one, 

 although by no means the commonest. Starting with it the various forms before 

 me, represented by four or more specimens, may be thus noted (the clothing and 

 apical half of antenna?, which are dark on all the forms, not here taken into 

 consideration) : — 



Form 1, Q . — Typical longus. Entirely pale. 



Form 2, 9 .—Like 1, except that half or more of the hind femora are 

 deeply infuseated, or black. 



Form. 3, 9. — Var. atricapillis. Like 1, except that part of the elytra is 

 black or infuseated; the dark part sometimes continued along the suture for a 

 short distance towards the base, and sometimes encroached upon by the suture ; 

 it occupies from one-fourth to three-fourths of the elytra, usually about one- 

 third ; occasionally the tip of the abdomen is dark. 



Form 4y^. — Like 3, but with a conspicuous black or infuscate, slightly 

 curved fascia, connecting the eyes ; tip of abdomen always black. 



Fortyi 5,9 ■■ — Head Avith a fascia as in 3, elytra black, with a wide but 

 somewhat irregular inedian tiavous fascia, metasternum, tip of abdomen and 

 parts of hind legs black, middle legs sometimes partly dark, and some of the 

 other segments of abdomen infuseated in parts.
