348 N10TEIS ON THE GENUS LISS0TE3. 



general worker. He says, however, that Howitt sent to 

 Westwood " specimens both male and female of L. 

 curvicornis, Boisd., under the name of L. cancroides, 

 Fab., Dr. Howitt stating- in his letter that the insect sent 

 as L. cancroides appeared to him to be identical with L. 

 curvicornis, grounding his opinion on an insect he had 

 seen in Count de Castelnau's collection. This view proves 

 to be correct upon comparison of the type specimen with 

 the insect sent to Prof. Westwood." 



There is in the Howitt collection a male labelled 

 " Lissotes cancroides Fab. Tasmania " (2), and as this 

 presumably is identical with the species sent to West- 

 wood, and stated by Parry to agree with the type of 

 curvicornis, I regard it as curvicornis. In the same 

 writing and the same collection is another specimen 

 labelled " Lissotes subtuberculatus Westw. Hobarton." 

 This also I believe to be correctly named (3), and if this 

 is the case then subtuberculatus is a simple variety of 

 curvicornis. 



The species is a rather common one about Hobart and 

 Mount Wellington, and as it varies considerably the 

 specimens at first sight appear to belong to two or more 

 species. The males may be regarded as belonging to the 

 following races or varieties: — 



I. CURVICORNIS, Boi (typical). (Figs, i, 2, 3, 4.) 



Rather flat; head and prothorax with a more or less 

 distinct bluish or pruinose gloss. Cuspidate mass of 

 mandibles subbasal, the miandibles when clenched enclos- 

 ing a large apical space. A rounded, usually shining 

 tubercle, half-way between each mandible and eye. Pro- 

 thorax with small punctures; apex not subtuberculate in 

 middle. 



The female of this form is also rather depressed and 

 its prothorax usually has a ])luish gloss. 



(2) Figure i; a second and identical specimen in the same- 

 collection is also labelled cancroides, and from Victoria; but. 

 Victoria I believe to be in error. 



(3) It agrees well with the descriptions; sec figure 5.
