Tenebrionidae yy-om Australia and Tasmania. 145 



Tlic following species is closely allied to Ectyche^ but differs 

 in the character of the tibiie, whicli arc all of the same form and 

 toothed (or ratlier, perJiaps, shortly s])iiied) externally. It is a 

 much smaller species ; and my specimen, which I owe to Mr. 

 Odewahn, of Gawler, having been carded, the gum (?) used has 

 such a tenacious property that it is impossible to get rid of it so 

 as to be able to examine the different organs satisfactorily. I 

 record it here principally to call the attention of Australian 

 entomologists to the subject. The occui'rence of two such 

 closely allied species so far apart suggests the probability that 

 these are by no means such isolated forms as they now appear 

 to be. It is not unlikely that they are ants'-nest insects. 



Ectyche'^ nana. 



E. ? breviter orata, nigra, opaca ; elytris subnitidis, crebre punctatis, 

 interstitiis rugosis. 



Hah. Gawler. 



Shortly ovate, opaque black, but the elytra slightly glossy, 

 covered above with long black erect hairs ; head and prothorax 

 finely and closely punctured ; clypeus not distinct from the 

 front ; prothorax transverse, convex, rounded at the sides and 

 anterior angles, the posterior acuminate ; scutellum inconspi- 

 cuous ; elytra scarcely broader than the prothorax, subnitid, 

 the punctures mostly ii-regular, or with slight indications of 

 rows, crowded, the intervals rugose ; body beneath dark brown, 

 closely punctured; antenna? and legs feiTUginous ; tibia? slightly 

 compressed, gradually dilated downwards, the outer edge 

 shortly spined ; tarsi with longish hairs beneath. Length 

 If line.

 Prothora.v lateribus foliaceis. 



Head transverse, inserted into the prothorax as far as the 

 eyes ; antennary ridges dilated ; clyjieus broad, separated frtmi 

 the front by a slightly arched line, strongly cmarginate in 

 front. Eyes transverse, entire. Antenna? small, thicker out- 

 wards ; third joint elongate; fourth, fifth, and sixth obconic; 

 seventh to the tenth submoniliform, the last obovate. Mentum, 

 as well as the labium, transverse, broader and truncate ante- 

 riorly. ]MaxiUary lobes small, the inner short and unarmed. 

 Palpi gradually thicker outwards; the maxillary Avith a short 

 basal joint, second as long as the two following together, the 

 last narrowly triangular ; the labial with a basilateral inser-
