268 THE INSECTS OF GAYNDAH, 



part and three first joints of the antennee red, and with the rest 

 of the antennge and the tooth of the third joint black. Thorax 

 red, nearly truncate in front, slightly narrowed behind, rounded 

 and with a recurved margin at the base, and with the thoracic 

 vesicles flat and extending along the sides nearly to the apex. 

 Scutellum black. Elytra about half the length of the abdomen, 

 broader than the thorax, lightly punctate, subtruncate and of a 

 chalybeate blue, with the base red. The abdomen has the basal 

 joints red, the apical black, but the lateral vesicles on all are red. 

 The coxse of the anterior legs are red. 



Two other species of this family are in the collection j but, as 

 they are single specimens and , gummed down on cardboard, I 

 cannot undertake to describe them. One looks like a Laius 

 though with eleven joints to the antennas, the other resembles a 

 small Malachius with short elytra and very long hind legs. They 

 will both probably be found to be new genera. Indeed I believe 

 that the Malacodermidce of Australia, though not very numerous, 

 w;ill, when properly investigated, exhibit a number of new 

 aud very curious, genera, particularly among the subfamily 

 Malf^chidcB. ,,
