longer, ocellate punctures which are more feeble on the disc ; laterally on each 

 side sharply impressed. Scutellum large, triangular, smooth. Elytra coarsely 

 punctate ; inter\-al between the punctures more or less wrinkled ; basal and 

 lateral impressions deep ; apical subsutural impression less deep. Sculpture of 

 underside of body rather finely reticulate, intermixed on the pro- and meta- 

 sternum with large ocellate punctures ; metasternum at sides plicate ; abdomen 

 very sparsely pubescent. Length 3 mm. Nogales, Arizona. 



" This species is very close to carntlcus but is more slender and has 

 the eyes more convex than any other of our species." 



This is merely a geographical variation distinguished by the 

 aeneous lustre of the head and thorax. The remarks by Mr. Schaeffer 

 about it being more slender with eyes more convex are misleading. 

 In the large series of schwarzi before us, there are many specimens 

 which are certainly more slender than this variety. Also the eyes 

 are not more convex but the median line is more deeply impressed, 

 which might give them that appearance. In certain specimens of 

 schwarzi, however, the impression of the median line is even deeper 

 than in the variety, so this character has no value. 



Localities. — 'Nogales, Arizona (Schaeffer). Arizona (Nicolay 

 collection). 



There are only two specimens of this variety known to us. The 

 type collected by Mr. Schaeffer is in the collection of the Brooklyn 

 Museum and a single female with only the state label is in the Nicolay 

 collection. There is no variation in the two specimens.

Body elongate ; scutellum small, smooth, triangular ; thorax usually 

 widest at base, rarely with sides parallel {IccvicolUs Le Conte) ; head 

 large with a median longitudinal impression ; eyes large, oval ; an- 

 tennae short, eleven jointed; elytra punctate, sides sinuate, a faint de- 

 pression between scutellum and humerus ; legs less, retractile than in 

 preceding genus, tibiae linear ; tarsi short ; presternum pointed behind ; 

 ventral surface of thorax grooved near margin for the reception of 

 antennae ; pubescence short and sparse. The dorsal surfaces of our 

 species are entirely black to coppery in color. In the " Biologia," 

 Waterhouse uses a key to separate the forms giving as the first divi- 

 sion, species with or without a lateral carina on the elytra. In study- 

 ing our species, we find that all are without it.
