obtuse ; surface like that of the head, confluently rugose-punc- 

 tate, lateral border narrowly raised, apical and basal border 

 clearly denned. Scutellum punctate. Elytra closely applied 

 to prothorax, and of the same width of base, soon expanding 

 without any denned shoulder, widest at middle; striate-punc- 

 tate, each elytron with nine sulcata striae, besides a short 

 scutellary stria, containing large approximate punctures on 

 the sides of the very convex intervals ; these also finely punc- 

 tate. Prosternum transversely rugose and punctate ; episterna 

 with large sparse punctures; abdomen nitid and minutely 

 punctate. Dimensions — 12 x 3 mm. 



Hab. — Northern Territory and North- Western Australia. 



Three specimens in the South Australian Museum, 

 labelled "Batchelor-, N.T., 12-12-12." Three more in Mr. 

 Idea's collection, labelled "N.W. Australia," and others 

 in the Macleay Museum, belong to a genus near 

 Dystalica. The combination of long and slightly enlarged 

 antennae, wide intercoxal spaces, thin and straight legs, non- 

 tomentose tarsi, is unusual. The elytral striae may be termed 

 sulci, while the punctures rather on the sides of the convex 

 intervals give them a crenate appearance, the base of the sulci 

 appearing smooth. Type, I. 3454, in South Australian 

 Museum. 



APPENDIX. 



Through the courtesy of Mr. H. R. Blair, the following 

 notes have been forwarded that will interest students of 

 our Tenebrionidce : — 



Erneax sculpturatus, Pasc. = Nyctoporis cristata, E^fefer-. 

 (From specimens in the British Museum. Pascoe's specimen 

 is either erroneously labelled, or was an imported specimen.) 



Ecripsis pubescens, Pasc. = A mmidium ciliatum, Erich. 

 (Pascoe had two specimens, and a third labelled "Tasmania," 

 in the British Museum collection. The last proved to be one 

 of a lot bought at Stewart's auction rooms, 1856, which came 

 from various localities, including Tasmania, St. Vincent, Cape 

 Verde. A confusion of locality labels is evident. A mmidium, 

 by the way, is a perfectly good genus, and not to be con- 

 founded with Anemia [Cat. Gebien]). 



Arcothymus coznosus, Pasc. = tristis, Montr. (Pascoe had 

 two specimens of tristis as well as the type of coenosus, so I 

 do not know why he did not recognize their identity. It is 

 probably another error of labelling, and the species should be 

 removed from the Australian list.)
