YII. 



The twelve species described in the following pages are nearly all 

 of exceptional interest, five of them requiring new generic names, 

 two of them representing a "tribe" (in Lacordaire's sense of the 

 word) of Curculionidse not previously recorded as Australian, 

 and another (Dyscliirius) pertaining to a very widely distributed 

 genus not previously recorded as South Australian. 



CARABIDiE. 



TRIGONOTHOPS. 



The difference between T. j^tlagiata, Germ., and lineata, Dej., 

 seems to consist mainly in the width and length of the bfack vittse 

 on the elytra ; both being from South Australia (Adelaide dis- 

 trict and Kangaroo Island), I suspect they are identical ; lineata, 

 Dej., is the older name. 



T. flavofasciata, Chaud., seems to vary almost infinitely in 

 markings ; I do not possess an example coloured quite like the 

 type, but have the var. nig7'o-signata, Chaud., with less dark 

 colour than the type and other vars. with black markings much 

 in excess of the type ; the species seems to have a wide range 

 (the extreme localities of my examples are Victoria and the 

 Lake Eyre basin), but does not appear to be very common. 

 T. longii^laga, Chaud., must be extremely like T. pallidicollis, 

 Macl., but the description of the latter is hardly detailed enough 

 to justify a decided opinion that species from such widely separated 

 localities are identical. 



DYSCHIRIUS. 



D. Torrensensis, sp. nov. Rufo-ferrugineus, elytris pedibusque 

 pallide testaceis (basi obscure triangulariter rufescenti, apice 

 obscure picescenti), mandibulis apice corpore subtus (pro- 

 sterno excepto) et prothoracis pedunculo piceis ; clypeo antice 

 emarginato : capite lae\i antice infequali ; prothorace rotun- 

 dato ; elytris oblongo-ovatis convexis postice angustatis sat 

 fortiter striatis, striis fortiter punctulatis, postice et striis et 

 puncturis obsoletioribus, interstitiis subconvexis 3", 5°, 7° que
