August, 1909.] THE VICTORIAN NATURALIST. 45 



specimens was found in the interior of the trunk of a large hollow 

 " Box " tree in October. The hollow was filled with damp earthy 

 material, in which were a number of Scarabseidse and their 

 larvae. Nothing appears to be known of the larval stage of 

 Hyperion, thus leaving an interesting entomological problem to 

 be solved. 

 761. Catadromus lacordairei, Boisd. (July-Nov.) 

 A fine, ornate species, widely dispersed ; usually found in 

 damp situations. 



C. latro, Tsch. 

 A larger species than the last-mentioned. Taken under logs 

 near water. 



Tribe — Trigonotomini. 



867. Hhytisternus cyathoderus, Chd. 



868. R. kevilaterus, Chd. (July-Nov.) 



Taken generally in open, grassy country, under logs, &c. They 

 resemble the species of Sarticus to a certain extent, but are more 

 depressed in form. Mr. Sloane has given a very useful tabular 

 view of twelve species (P.L.S. N.S.VV., 1894, 2nd series, p. 437). 

 Sarticus discopunctatus, Chd. 

 S. esmeraldipennis, Cast. 



Two very common species. Taken almost anywhere, under 

 logs, &c., from March to December. S. esmeraldipennis, Cast., 

 is given as a synonym of S. obesula, Chd., in Master's Catalogue. 

 Mr. Sloane, however, regards «S'. esmeraldipennis as a good 

 species, and has redescribed it (P.L S. N.S.W., 1903, part 3, p. 

 617). 



878. Chlcenioidius meMei, Montr., Ann. Fr., i860, p. 238. 

 This species is well known as C. herbaceus, Chd. The following 

 note by Mr. Sloane explains the change of name : — " It was 

 described from New Caledonia (where also C. prolixus, Er., is 

 found) by Montrousier in i860. Chaudoir did not describe it as 

 C. herbacetis till 1865, so his name sinks to a synonym of 

 C. mellei, Montr." 



881. C. prolixus, Er. 



909. Simodo7itus atistralis, Dej. (April-Dec.) 



S. ma^idibularis, 81., P.L.S. N.S.W., 1894, part 4, p. 574. 

 Both species occur plentifully throughout the Mallee, sheltering 

 under sticks, &c. 



Tribe — Sphodrini. 

 Lcemostenus complanalus, Dej. 

 An introduced European insect, known for nearly 20 years in 

 Australia as Prislonychus auslralis, BIkb. Sometimes found in 

 houses and grain sheds. 

 926. Platynus marginicoUis, Macl. (Nov.) 

 Very plentiful under logs near water.
