216 LAMELLICOENIA. 



Fam. KUTELID^. 



Subfam. ANOMALINJE. 



The chief distinguishing character of this subfamily lies in the deflected labrum, the 

 anterior middle part of which curves downwards so that the front edge is turned under- 

 neath towards the roof of the mouth. Hence, without dissection, the basal part of the 

 organ, more or less sinuated in front, is alone visible. It is incorrect to term this 

 peculiar conformation " labrum emarginatum " as Erichson and after him all the chief 

 writers on the Lamellicornia have done, the middle of the true front edge of the labrum 

 being obtusely rounded and sometimes even produced, not emarginated. This difference 

 is important inasmuch as it lessens the divergence between the subfamilies Anomalinse 

 and the Geniatinse, with their allies the Anoplognathina? and the neighbouring groups, 

 two great series of forms which have hitherto been widely separated in the current 

 classifications. 



PHYLLOPERTHA. 



Phyllopertha, Stephens, 111. Brit. Ent, Mandib. hi. p. 223 (1830) ; Erichson, Naturgesch. d. Ins. 



Deutschl. hi. i. p. 627; Lacordaire, Gen. Col. iii. p. 327; Burmeister, Handh. der Ent. iv. 2, 



p. 512 (Anomala pars, olim, Handb. iv. 1, p. 239). 

 Anisoplia (Latreille, Castelnau), Eairmaire, Ann. Soc. Ent. Fr. 1870, p. 378. 



Although this genus is generally adopted it has never been satisfactorily defined as 

 distinct from Anomala, and many species have, in consequence, been referred to it which 

 have little in common with the typical P. horticola. The two Mexican species included 

 in Phyllopertha by Blanchard appear to me decidedly not to belong to it, one being an 

 Anomala, and the other an Epectinaspis. The following species is a Phyllopertha in 

 its general form and the slenderness of its hind legs in all their parts, and in the loose 

 villosity of the under surface of the body ; but it differs greatly from Phyllopertha in 

 the mouth-structure, the mandibles being reduced to very narrow flat tapering blades, 

 lying closely to the roof of the mouth, and the maxilhe having two teeth only. Abrupt 

 degradations of mouth-structure occur, as I shall have to show, also in a group of 

 Anomalce widely different from Phyllopertha, and they cannot well be treated as generic.
