gorrhinus ; but these specimens do not agree with Gestro's 

 description. I Avrote about the species (my 10804) to Dr. 

 Gestro as follows : — " This species is in several collections 

 as ptery gorrhinus, but it does not agree with your description, 

 as the prothorax is red, and the maculae are never ten in num- 

 ber, but eight or nine, of which three or four are together be- 

 yond the middle and never more than two at the apex (in your 

 description you say three)." In reply he stated : *' Nearly all 

 our Brenthids are with Prof. Senna, to whom I sent your speci- 

 mens. Senna says your 10804 is Ectocemus 10 maculatus, 

 Montr," In a later letter lie confirmed this identification, and 

 stated : " I think that ptery gorrhinus is simply a colour var., 

 and in consequence the two cannot be separated, pterygorrhinus 

 is darker." 



In recently examining twenty-four specimens of the species 

 I found that one of them has three apical spots on each elytron, 

 but the one usually missing (at the junction of the fourth, fifth 

 and sixth interstices) is very small. Several specimens sent 

 to me recently by Mr. Elgner from Cape York have the pro- 

 thorax quite black, but in all the others it is of a more or less 

 dark red. Queensland specimens vary in length from 16 to 28 

 mm. (including the rostrum). 



In Masters' Catalogue of the New Guinea beetles, ruficauda 

 Bates (1394) is given as a synonym. 



Orychodes digraf/ima, Boi.- 



This species (originally described from Dorey) occurs abun- 

 dantly in the vicinity of Cairns. In appearance it resembles an 

 Ectocemus, but has a stout spine directed at right angles to its 

 length, immediately behind each eye ; the spine, however, is 

 usually very indistinct in the female. The length (including the 

 rostrum) varies from 9 to 20 mm. I have to thank Dr. Gestro 

 for the identification of the species. 



Chrysomelid^. 

 Sub-family, Chrysomelides. 

 The late Mr. Jacoby's paper in Ann. Soc. Ent. Beige, 1898, 

 was unknown to me at the time I drew up the descriptions of
