INTRODUCTION". 



Sub-Order II. POLYCERATA. 

 ( = PolymorphA; Sharp ; Polyphaga^ Ganglbauer., ex parte.) 



We have before discussed this sub-order (p. 48), and need here 

 say but little more with regard to it. Considering that the names 

 of the main divisions have mostly been based on antennal cha- 

 racters (Clavicorxia, Serricornia, Longicornta, etc.), it might 

 be well to adopt the term Polycerata, rather than Polyphaga or 

 Polymorpha ; but this is, of coarse, merely a matter of taste. 

 As here considered, the sub-order differs from the Polyphaga of 

 Ganglbauer (Munch. Kol. Zeitschr. 1903, Band i, Lief, hi, p. 302) 

 only in not including the Lamellicornia. 



In subdividing the sub-order, the Clayicoreta and Serri- 

 cornia (including the Malacodermata.) are considered, for 

 convenience' sake, as having a separate equivalent value and 

 are not included under the larger complex named by Ganglbauer 

 Diyersicorkea. Ganglbauer himself has at different times con- 

 siderably altered his views on some of these points (cf. I. c. supra 

 with Die Kafer Mitteleurop. vol. iii, p. 408, and vol. iv, pp. 1-3), 

 and will probably be found to have altered them further when the 

 remainder of his valuable work has been published ; at present, 

 this has only reached the conclusion of the Clavicornia. 



The groups here adopted may be divided as follows : — 



I. Wings belonging to Type II (p. 40), without cross- 



veins or loop StaphylinoideAj p. 71. 



II. Wings belonging to Type III (p. 42), but with the 



venation very variable, especially in the smaller 

 forms. 



i. Gular sutures and lateral sutures of the prothorax 

 distinct. 



1. Tarsi variable, with 1-5 joints, rarely hetero- 



merous (in one or both sexes of certain 

 Clayicornia). 



A. Antenna?, as a general rule, clavate (with 



exceptions) Clayicornia, p. 95. 



B. Antenna?, as a general rule, serrate or filiform 



(with exceptions) Serricornia, p. 131. 



2. Tarsi heteromerous, that is to say, with 5-5-4 



joints respectively (except the male of Moplion, 

 which has the anterior tarsi 4-jointed). 



Heteromera, p. 155. 



3. Tarsi pseudo - tetramerous or crypto - penta- 



merous, the fourth joint being very small 



and connate with the fifth . . Phytophaga, p. 176.
