D. ventralis, Lea. 



The tip of the subapical segment of the abdomen of the male of this species 

 has two comb-like processes, <^-^^ and largely because these were not mentioned by 

 Fauvel in his description of the abdomen of the male D. cephalotes,, I presumed 

 that D. ventralis was not that species. On examining some greasy specimens 

 recently, however, the combs were scarcely visible, and so they might easily have 

 been overlooked by Fauvel ; it would appear, therefore, that the names are 

 synonymous. *^'^'*^ 



DiCAX LONGICEPS, Fvl. 



A specimen from Ebor (New South Wales) in the Queensland Museum 

 probably belongs to this species, but differs from the description in being smaller 

 — 7.5 as against 9.5 mm. 



DicAX DESERTi, Blackb. 



Blackburn's description of the colour of D. deserti is practically identical 

 Vv^ith that of Fauvel's D. ruhripennis, except that the latter did not mention 

 the tip of the abdomen as partly red ; its legs vary from a dingy piceous-brown 

 with the tarsi and front coxae paler, to deep black, with the tarsi and meta- 

 sternum of a dingy brown, the elytra vary from rather dark red to bright 

 castaneous. Two specimens, from Oodnadatta, are labelled as cotypes, 

 although in the description only Storm Creek was mentioned. 



Var. Four specimens, from Mulwala, appear to belong to the species, they 

 differ from the typical form in being smaller, 6.5-7 mm., the legs deep 

 black, except that the tarsi are obscurely brown, and the metasternum blackish. 

 Their colours, in fact, are exactly as on some of the larger ones, but I have seen 

 no specimens intermediate in length between 7.5 and 10.5 mm. 



DiCAX RUBRIPENNIS, Fvl. 



A cotype of this species (from the British Museum) differs from small 

 specimens of D. deserti in having the abdomen entirely black, the head, pro- 

 thorax, and elytra with a faint pruinose gloss (not mentioned by Fauvel) and 

 the punctures somewhat smaller and sparser.

(-*) Since this was written I have received a cotype of cephalotes from the British Museum, 

 which puts it beyond question.
