LOMAPTERA DUBOULAYI, Thoms. 



PL vii., fig. 9. 



In this species the prothorax and elytra usually have a 

 complete flavous border, narrower at apex of prothorax, 

 and wider at apex of elytra than elsewhere. Frequently near 

 the apex of prothorax a small spot extends inwards on each 

 side, and occasionally a vague spot may be traced on each 

 shoulder. 



In the National Museum there are two females, from 

 Cape York and Endeavour River, that have no flavous border 

 to the prothorax. The elytra also at first appear to be 

 without such a border, but on a close examination the sides 

 are seen to be obscurely diluted with red. 



LOMAPTERA CINNAMOMEA, Thoms. 



PI. vii., figs. 10, 11. 



This species varies from a form with the prothorax 

 immaculate to one with a wide M in the middle of same, 

 but the common form has three disconnected spots, of which 

 the middle one is longer than the others (as on the type). 

 Sometimes there is also a vague spot towards each side at the 

 apical third. 



The female differs from the male in being wider, elytra 

 less narrowed posteriorly, pygidium more pointed, abdomen 

 evenly convex along middle, and front tibiae with an obtuse 

 tooth near apex, in addition to the terminal tooth. 



LOMAPTERA DEYROLLEI, Thoms. 



This species was described as being entirely of a clear 

 olivaceous-green; but Schoch, in redescribing it, says it 

 resembles lucivorax < 21 ) in the blackened anterior edging of 

 the elytra, and, again, "elytra darker and duller-green with 

 blackened anterior edge, but not so wide and intense as in 

 lucivorax.'" ( 22) Thomson did not mention the tibial dentition, 

 but Schoch described the front tibiae of the male as bidentate. 

 The shape of the pygidium was mentioned by neither. 



It appears possible that Thomson really had two species 

 before him. At the time he described deyrollei, he men- 

 tioned having four specimens, . and quite possibly the type 

 belonged to australis, and the specimen described by Schoch 

 to a form of yorkiana with elytra darker at the base than 

 usual. 



Thomson described the elytra as "basi laevia deinde 

 punctato-striolata, striolis transversis," characters which
