Burmeister mentioned the differences of sculpture which distinguish A. hopfneri (as a 

 variety) from the more southerly forms of A. inconstans, but did not notice the pecu- 

 liarity of dentition of the anterior tarsal claws in the male, which I find quite constant. 

 The markings of A. hopfneri are also different from those of A. inconstans. The sutural 

 vitta of the elytra is nearly always dilated in the middle, and the apical margin has a 

 broad velvety-black border seldom entirely absent. The broad trapezoidal spot of the 

 thorax reaches the base, but there is generally a pale transverse streak in the middle of 

 the basal part. An example from Peras is figured.

In the male the larger claw of the anterior tarsi is long, subtriangularly dilated near 

 the base only, and the upper tooth is nearly as long as the lower ; in the female the 

 upper tooth is longer than the lower. The larger size (16-17 miilim.), more distinctly 

 tricostate elytra, with thickly punctured intervals, flatter pygidium, much more obtuse 

 thoracic hind angles, and different elytral markings (broad and dark discoidal streaks 

 being the prevailing pattern) further distinguish the species from A. hopfneri. The 

 subtridentate anterior tibiae in the female is a more constant character in this species 

 than in A. hopfneri. 



The examples from Chiriqui (two in number) differ from all the Mexican and Guate- 

 malan individuals by the elytra being yellow with the suture (narrowly) and the humeral 

 callus only black, and by the narrower and less punctured intervals between the costae. 



Burmeister, in his appendix, stated his belief that his species was probably the 

 A. lurida of Fabricius — a suggestion of change of name promptly adopted, as usual in 

 such cases, by subsequent writers. The description of Fabricius, however, as given in 

 the Syst. Entom., does not in the least apply to A. inconstans in any of its varieties. 

 The " caput nigrum " and " elytra punctis duobus ad suturam et unico versus apicem " 

 must refer to some species of a different group of Anomalce. The country of Fabricius' 

 species was unknown. We figure a Guatemalan specimen of A. inconstans.
