Eab. Mexico, Toluca {Edge). 



A large series of examples, nearly all males. The labrum in this species is small and 

 depressed in the middle, with the front margin strongly deflected and in the middle 

 slightly produced. The mentum is very much less flattened in the middle than is usual 

 in the subfamily.

 Deutsch. iii. p. 616 (1848) ; Burmeister, Handb. der Ent. iv. 1, p. 230 (1844). 



Upwards of 300 species of this well-known genus have been described. It is 

 abundantly represented in the tropical and north temperate zones of both continents, 

 but does not appear to extend to the south temperate zone or to Australia and the 

 Oceanic Islands.

A numerous series, similar in the wide range of variation in the number of the dark 

 elytral spots (in the darkest specimens forming undulating belts) to the North- American 

 form. The clypeus is semicircular (widening behind); and the anterior claw-joint 

 is without conspicuous tooth beneath, with the upper part of the cleft apex as long as 

 the lower. The brassy-brown central area of the thorax generally reaches the base, 

 where it is indented by a broad bilobed spot of the testaceous ground-colour. 



2. Anomala discoidalis, (Tab. xil. fig. 2.) 



A. undulatce quam proxime affinis, sed differt thoracis macula nigro-senea trapezoidali distincte delimitata, 

 limbis testaceis laterali et basali latis ; elytris fulvo-testaceis, macula parva medio juxta suturam nigra, 

 raro disco et callis humeralibus apicalibusque maculatis ; tborace paullo subtilius disperse punctato, 

 margine basali medio late interrupto.
