The second species, A. ferrugineus, is from Adelaide. Its length is 2| lines. lu 

 size aud form it nearlj' resembles the small European insect known as Lixus nifitarsis 

 of Schonherr: in colour it is of a somewhat deeper red than the Apion fiumentarium : 

 the head, rostrum, sides and under parts of the thorax clothed with yellow scales ; a 

 small spot at the humeral angle of the elytra, and a ring at the apex of each elytron 

 are also formed by yellow scales : head and thorax with scattered punctures ; elytra, 

 slriato-punctate, and with the interstices flat. 



Mr. Janson exhibited specimens of the following Coleoplera, brought by him 

 before the Society on previous occasions under the names of Homalota subterranea 

 and Haploglossa rufipennis, and made the following observations respecting them: — 

 " Homalota subterranea, Muls. This appears to coincide, as Mr. Waterhouse 

 states, with an insect in the European Collection at the British Museum furnished by 

 Dr. Kraatz, under the appellation of Homalota scapularis, Sahlberg. I had, however, 

 prior to bringing the subject under the notice of the Society, carefully compared my 

 specimen with the descriptions both of Sahlberg and Kraatz, and found disparities 

 which precluded me from referring it to that species: thus, Sahlberg (Insecta Fenuica, 

 372, 50) described his Aleochara scapularis as being ' barely one line long,' and as 

 having the 'abdomen shining, scarcely punctulale,' and the characiers attributed by 

 Kraatz (Naturgesch. d. Ins. Deutschl. ii. 291, 100) are not in accordance with those 

 presented by my example; finally, my specimen appeared to me to coincide well with 

 both Mulsant's and Kraatz's descriptions of H. subterranea, and furthermore its 

 occurrence in a nest of Formica flava led me unhesitatingly to refer it to that species: 

 if, however, an insect received at the British Museum from Dr. Kraatz as the Homa- 

 lota subterranea of Mulsant is really the species described by that author, it is not 

 only specifically distinct from the insect to which I had applied that name, but 

 pertains to a diiferent section of the genus. 



" Haploglossa rufipennis is not the species so designated by Kraatz, as I have 

 convinced myself by a comparison with examples sent by him to the British Museum, 

 but is perfectly distinct from an insect which I regard as the true H. pulla of Gyllenhal, 

 being less coarsely punctate, having the antennse conspicuously stouter, their articula- 

 tions otherwise proportionate, &c., &c. The following synonymy of the two species will 

 probably prove correct : —

 "The first is said by Gyllenhal to inhabit Fungi; the only indigenous specimen 

 which I have seen, the one now exhibited, was given me by Mr. H. S. Gorham, who 

 captured it in the Isle of Wight, he thinks, in an ant's nest beneath a stone, and who, 

 I believe, has other examples. 



" The second, M. Fairmaire informs us (J,, e.), he found abundantly in the nests
