Hab. Mexico, Juquila {Salle, Hoge), Jalapa {Hoge). 



I have adopted the MS. name given to this distinct species in the Salle collection.

All the three colour-varieties, described as species by Newman, with apparently rare 

 intermediate gradations, are found at Orizaba. In each variety, certainly in two of 

 them, there are males and females, the colours are therefore not sexual as Burmeister 

 described them. 



"We have received a large number of examples from Orizaba and also from Coatepec ; 

 two from the latter locality are figured. 



II. Tarsi anteriores unguibus haud apice fissis, dente superiore dorsali setiformi; 

 intermedii unguibus dente parvo vel simplicibus. Tibiae posticce breves, sub- 

 triangulares. 



95. Anomala rhizotrogoides. (Tab. XIII. fig. 22.) 



Anomala rhizotrogoides, Blanch. Cat. Coll. Ent. i. p. 186 \ 

 Hab. Mexico 1 , Vera Cruz {Salle, Hoge). 



This species differs from the typical Anomaloe in many points of structure ; the ligula 

 is narrowed and entire at its upper edge; the labrum is straight, and without the usual 

 concavity in the middle, besides being extremely short, with the deflexed apex short 

 and obtuse; the vertical edge of the semiovate concave clypeus is thickened and 

 projects in front considerably beyond the mouth; and, lastly, the hind tibiae are short, 

 about two thirds the length of the tarsi, and dilated from base to apex. The antennal 

 club (especially in the male) is very long, slender 3 and curved, the mesosternum rather 

 narrow and declivous, the anterior tibiae bidentate, and the mandibles and maxillae short, 

 robust, and dentated. The differences in labrum and tibiae might justify the generic 

 separation of A. rhizotrogoides if they were found to hold good in the few species
