of New Deretaphri. ccxi 



Gibbon, to whose courtesy I am indebted for the opportunity of examining this 

 and many other most interesting novelties from the same locality. I have named 

 this insect in honour of Mr. Wollaston, whose profound knowledge as a Coleopte- 

 rist is only equalled by his kindness in imparting it. 



Deeetaphbus Erichsoni. 



Rufo-piceus ; capite puncto, puncus minutis sparsis distinctis ; prothorace 

 puncto, punctis majoribus crebrioribus, medio longitudinaliter vage im- 

 presso ; elytris carinatis, carinis postice interruptis in tuberculos salientes 

 divisis, interstitiis profundis serie unica pimctorum magnorum impressis. 

 (Corp. long. -47 unc. lat. '14 unc.) 



Pitchy red, approaching to black towards the apex of the elytra: head im- 

 pressed with a small epicranial fovea, and there is another more conspicuous 

 immediately adjoining the epicranial margin of each eye : the entire epicranium 

 is minutely punctured : prothorax punctured more coarsely and regularly than the 

 head : elytra carinated, the carinee interrupted towards the apex, and broken, as 

 it were, into salient, irregular, and sometimes rather acute tubercles : under sur- 

 face of the insect uniformly punctured, pitchy red, shining ; coxae, together with 

 the space immediately surrounding them, and apex of abdomen, darker : legs 

 pitchy black, with redder femora; exterior margin of tarsi strongly serrated. 



Habitat : Adelaide, South Australia. There are two specimens, from the col- 

 lection of Mr. S. Stevens, in the cabinet of the British Museum. I have named 

 this in honour of the late Professor Erichson, whose memory I revere as that of 

 one of the greatest Coleopterists the world has produced. 



The described species of Deretaphrus, exclusive of those which Erichson pro- 

 posed to remove to the genus Bothrideres, are now four in number: 1. D. fossus, 

 Newman, Entom. 403, synonymous with Sigerpes piceus of Germar. 2. D. 

 Wollastoni, Newman, described above. 3. D. Erichsoni, Newman, described 

 above. 4. D. puteus, Newman, Entom. 404. They are all peculiar to Austra- 

 lia, feeding under the bark of trees, principally Eucalyptus.

BOMBYX (DORATIFERA ?) OxLETI. 



Fcem. Castaneofusca; alarum limbo anticarum lato albido, posticarum ciliis 

 tantum pallidis ; abdomen subtus apice densissime lanugine fusco vestitum. 

 (Corp long. 1*6 unc. alar, dilat. *6 unc.)
