<S2 H. I. Carter: 



species H. (allecula) angusticollis, Boh. Fabricius' description is 

 misleading, not only in its brevity and misplaced genus, but in the 

 words "caput nigrum," "thorax niger," whereas in fresh speci- 

 mens the whole insect is ferruginous. Boisduval's few words of de- 

 scription of the species Allecula australis apply also to this insect, 

 and is so determined by Blackburn. 



(4) //. ruficoniis, Blackb. — This name was praeoccupied by 

 Macleay, and Borchmann suggested the name rufulicornis. 



(5) If I am correct in merging the Australian species of Allecula 

 with Homotrysis, II. rufa, Blackb., is praeoccupied by A. rufa, 

 Solier, which may be the same insect. I have not been able tol 

 get M. Solier's paper, so that I am unable to give any opinion on 

 this (vide infra). 



Allecula. — This genus has not been clearly defined, and has been 

 used as a "dumping ground " for Australian species of a very dif- 

 ferent facies. Following the classification id' Solier and Mulsant, 

 who reserve this genus for species having (1) only one small lamella 

 on the penultimate joint of each tarsus. (2) antennae with joint ."5 

 much shorter than i, I find that none of the so-called " Allecula " of 

 Australia comply with condition (1), while //. rufa, Blackb.. is the 

 only species I have examined which fulfils condition (2), and that 

 species, like all the others, has two distinct lamellae on the anterior 

 four feet, and one on the two posterior. Moreover, except in size 

 and colour, and in variable proportions in size of antennal joints, 

 1 cannot distinguish between Allecula and Homotrysis. The species 

 described under these genera have therefore been classed together as 

 Homotrysis. After deducting those species which have been con- 

 sidered as Hybrenia, or other genera, and synonyms, I find 37 sp. 

 described, to which I propose to add two new species. The following 

 eight species have not been identified : — A. costata, Haag., A. cylin- 

 dricollis, Bois.. A. foveicollis, Hope. A. Gouldii, Hope, A. Melan- 

 ckolica, Hope. A. nigricans, Hope. A. rotundicollis, Casteln., .1. 

 rufa, Sol. 



Notes on flic Species. — //. ruficornis, Macl., and TI . subgemina- 

 tiis, Macl.. are closely allied in size, form and sculpture, but the 

 former has red antennae, the latter dark antennae, while the striae 

 air narrowly branched, at least on the apical part of elytra, forming 

 the subgeminate striae referred to in the description. 1 have only 

 seen three specimens of the latter. 



//. laticollis, Hoh.. is a common Sydney insect, found also in many 

 other parts of New South Wales (Blue Mountains. Illawarra, 

 Northern Rivers district), and was described as from Sydney. It is 

 strange that Blackburn apparently failed to identify it.
