 Lebiides. 



Trigonothops longiplaga, Chaud. 



I have recently received from various localities examples 

 scarcely separable from this species, and an examination of these 

 and of specimens from Tasmania of T, pacifica, Er., appears to me 

 to point strongly to the conclusion that T. longiplaga, Chaud., 

 cannot be considered other than a variety of T. pacifica. De 

 Chaudoir distinguishes it by the following characters — (a) head 

 less narrowed behind the eyes, (b) prothorax less short and a little 

 less rounded laterally, (c) elytra more elongate and less strongly 

 striated, with flatter interstices, (d) spots on the elytra more 

 yellowish, the anterior one sending out a narrow prolongation to 

 the base. 



Of my Victorian examples, — which I know were taken in com- 

 pany and are certainly conspecific irUer se, — only one presents all 

 the characters attributed to longiplaga ; they all agree in having 

 the anterior elytral spot prolonged to the base, but two of them 

 have the prothorax distinctly shorter than the other, and of these 

 one has the elytra distinctly wider than the other. The elytra 

 are striated a little less strongly than in one of my Tasnianian 

 examples of T. pacifica, but I have another Tasmanian example 

 which is striated quite as strongly as the Victorian specimensj 

 but presents no other character distinctive of longiplaga.
