IV. POLYMORPHI. 



Of the ten subfamilies brought together under this 

 heading, the two first only have a natural affinity. The 

 others, as explained at the beginning of Part I., are 

 isolated and heterogeneous, being, in fact, each of them 

 the type of a higher division. To effect their rational 

 arrangement it would be necessary to take into account 

 all the exotic forms, when it would probably be found 

 that many or most of the subfamilies and their genera, 

 constituted for the reception of European species, would 

 have to be modified or exploded. With regard to the 

 first two subfamilies, they might be classed together as 

 one group Petiolarii, equivalent to the Areolarii, &c, 

 established by Wesmael ; but it would avail nothing to 

 commence a system of division which could be carried 

 no further. 



XIV. EUPHORIDES. 



Maxillary palpi 5 — 6-, labial 2 — 3-jointed. Occiput margined. 

 Clypeus rounded, usually discrete, marked with a punctiform 

 impression on eacli side of the base. Antennae varying in length 

 and in the number of the joints ; in Strcblocera geniculated and 

 with an elongate scape ; in Eustaloccrus geniculated and clavate. 

 Mandibles hardly bidentate. Mesothoracic sutures distinct or 

 obsolete. Fore wings with 2 cubital areolets, sometimes obsolete ; 

 pncdiscoidal often confused with the 1st cubital; radial either 

 cult rate, reaching nearly to the tip of the wing, or minute, sub- 

 lanceolate or semicordate, the metacarpus being then shorter or 

 not longer than the stigma. Pobrachial areolet of the hind wings 

 scarcely shorter than the prsebrachial ; praebrachial transverse 

 nervixre sometimes obsolete. Abdomen petiolated ; suturiform 

 articulation obsolete; segments 2 — 3 much longer than the rest,
