It appears to me pretty certain that A. amceniis, Pase., is a 

 mere synonym of lateralis, Bohem., nor can I help thinking that 

 Mr. Pascoe was mistaken in the opinion that he was describing 

 the male. If it was the male, either the sexual characters of that 

 species are very different from those of allied forms, or the author 

 passed over unnoticed a very remarkable structure in the palpi. 

 The description of the antennas, moreover (subtiliform with the 

 apical three joints a little shorter than the rest and somewhat 

 compressed), seems suggestive of a female, although I should say 

 that I have not seen an Apellatus of either sex whose antennf^e 

 quite present those characters. I conclude therefore that 

 A. lateralis, Bohem. (lateralis, Pasc. — amoenus, Pasc), is a species 

 I have not seen of which it is doubtful whether the male is 

 known. 



I should say it is equally certain that A. Mastersi, Macl., is the 

 female of A. jKtlpalis, Macl. The colour differences of the two are 

 of no account— the two species before me, of which I have both 

 sexes, vary even more in colour. It is possible that A. palpalisj 

 Macl., is the same as A. lateralis, Bohem., but this I think wants 

 proof. One of the species before me may, I think, be Sir W. 

 Macleay's insect (although its habitat in South Australia suggests 

 doubt), but that author's description is not deffnite enough for 

 certainty. If it be jjalpalis, I think it is probable that palpalis 

 is distinct from lateralis, as the antennal structure in my ex- 

 amples does not quite agree with that of lateralis* 



I may add that the absence or presence of a slight pubescence 

 on species of Apellatus is of no importance ; very fresh specimens 

 have a slight pubescence which is easily rubbed offl 



A. apicalis, from Western Australia, is known only by a female, 

 but it is at once distinguishable from the other Apellati by its 

 different puncturation as well as different style of marking.

* Since writing the above I have examined the types of A. palpalU and 

 A. Mastersi in the Macleay Museum. They are certainly male and female 

 of one species, and are identical with the S. Australian species mentioned 

 above. There are in the Macleay Museum also two examples labelled 

 *'M. Interalis, Pasc," and these also are identical with A. palpalU.
