MB. F. P. PASCOE ON THE CURCULIONIDJE. 199 



Gasterocercus. In habit it is like Plinthus Sfurmii. But for the 

 well-marked metathoracic episterna, its affinities would seem to 

 be nearer to Porojpterus. 



Omydaus plinthoides. 0. ovatus, niger, opacus, squamis sordide 

 griseis conspersus ; capite rostroque basi confertim punctatis ; antennis 

 piccis ; prothorace reticulato-punctato, piinctis sa;])e confluentibus, 

 in medio manifeste longitudinaliter cariiiato ; scutello subtransverso ; 

 elytris seriatim favosis, interstitiis alternis paulo elevatis; corpore 

 infra vage punetato, squamis subsilaceis adsperso ; pedibus rude 

 punctatis, setulis nigris erectis sparse adspersis. Long. 5 lin, 



llah. New South Wales (lUawarra). 



The following genera, as far as JEsycliora, belong to that part 

 of Lacordaire's "groupe Cryptorliynchides vrais," which has a 

 pectoral canal extending to the intermediate coxse, and its apex 

 open * ; those of them which have the three intermediate seg- 

 ments of the abdomen equal, and are allied to Pezichus, may be 

 tabulated as follows : — 



Femora grooved beneath for the reception of the tibise. 

 First tarsal joint moderate or short . . Syhulus. 



First tai'sal joint long Glyphagia. 



Femora not grooved beneath. 

 Club of the antennsD cylindrical. 

 Elytra broader than the prothorax at the base. 



{Pcziclms, Watcrli.). 

 Elytra not broader than the prothorax. Endymia. 

 Club of the antennae ovate Pmiopides. 



Endymia.

* " En gouttiire " of Lacoi'dairo. This character, however, must be taken 

 with a certain reservation. In Cryjptorhynchus lapathi the canal is not open 

 at the apex to the same degree as in Macromerus crinitarsis (I take these two 

 well-known forms as an illustration) ; it is, I should say, slightly cavernous : but 

 then the mesosternum, in which the apex of most of the Cryptorhynchinae ter- 

 minates, is not vaulted, or raised at the edges in the same way as in the truly 

 cavernous structure. But in this as in other characters there are transitions 

 which it is scarcely possible to limit.
