56 Mr. Arthur M. Lea's Revision of the 



The species is certainly the most variable of the sub- 

 family as regards its elytral markings, although the sculp- 

 ture is remarkably constant. There is, however, one very 

 remarkable variation ; this occurs in the carina dividing 

 the two apical central areolets of the prothorax. In about 

 half of the specimens this is entire, as in other species of 

 the genus, but in the others (more frequently in the females 

 than in the males) it is longitudinally divided so as to 

 appear as two carinae ; as a consequence the median 

 areolet, in these specimens, appears to be connected by a 

 very narrow groove with the apex, I can be certain that 

 I am not here confusing two allied species, having taken 

 numerous specimens in cop., and in numerous pairs the 

 sexes differ in this respect. 



In size it varies from 6 to lOi mm. 



The typical form and the variety liaemorrhoidalis * are 

 very abundant on the undergrowth in heavily timbered 

 parts of Tasmania. 



I have seen an occasional specimen in which the elytra 

 were so indistinctly tipped with red, that unless closely 

 looked for it would escape observation ; but usually in 

 haemorrhoidalis the apex is very distinctly tipped with 

 red ; in a rare form the red is continued along the sides to 

 the base and up the suture for a short distance {margina- 

 tus, goryi) and in another to the base both at suture and 

 sides {luguhris)] in several specimens the black occupies 

 an elongated somewhat /\ (compo reversed V)"shaped 

 space {lylagiatus)^ ; in one specimen from Mount Welling- 

 ton the disc of each elytron is infuscate only (an unnamed 

 variety). 



It is to be noted that in this (as in other species of the 

 genus) the prothorax does not always contract in the same 

 way in different specimens ; usually it is quite strongly 



* I have examined a long series of specimens and cannot support 

 Mr. Blackburn in his contention that haemorrhoidaJis and rufipennis 

 (salehrosus) are really distinct, though closely allied species, and 

 which can be distinguished by " the isroduced piece of each joint 

 beginning with the sixth " ; in the sexes of course there is con- 

 siderable difl'erence in the antennae, but there is just as much 

 individual variation in the males of one form as there is between 

 the males of the two forms ; moreover, a slight diflerence in position 

 from which the antennae are viewed makes a considerable difference 

 in their appearance. 



f Mr. Waterhouse suspected tliat this form was only a variety of 

 ]i<iefaor)]ividalis.
