24 (4). @dionychis haroldi. 
Obscure piceous, the head and the antenne black; thorax fulvous, impunctate ; elytra extremely minutely 
punctured anteriorly, obscure fulvous, the suture and a broad longitudinal stripe on the dise black. 
Length 2-24 lines. . 
Of broad and rather convex shape; the head nearly black, with a few punctures near the eyes only, the 
frontal tubercles broad and distinct, the eyes large and widely separated; antenne short and robust, 
black, the lower three joints often obscure fulvous ; thorax strongly transverse, the sides rounded in front 
only and rather broadly margined, the surface entirely impunctate, somewhat convex, and shining; 
scutellum black ; elytra rather short, broad, and convex, extremely finely and closely punctured, fulvous,’ 
with two broad longitudinal black stripes—one sutural, generally narrowed towards the apex, the other 
discoidal, of nearly equal width, but slightly narrowed at the shoulders ; underside and anterior legs more 
or less piceous, the posterior legs fulvous. 
Hab. Mzxico, Tepetlapa in Guerrero, Cuernavaca in Morelos (H. H. Smith), Jalapa 
(Hdége). 
Numerous examples. (. haroldi may be known from the other striped species of 
(Edionychis by its short convex shape and the width of the black elytral stripes, these 
being as wide as, or in some specimens even wider than, the fulvous intervening spaces ; 
the discoidal stripe is always wider than the lateral fulvous portion. In one specimen 
the sutural stripe is greatly narrowed before the apex, and the discoidal one interrupted 
at the same place.

To the Mexican locality given, add :—Dos Arroyos in Guerrero (H. H. Smith), Aca- 
pulco, Iguala, and Chilpancingo, all in Guerrero, Huetamo in Michoacan (Hoge). 
Very variable in size, some specimens being nearly twice as large as others; the 
spots are sometimes confluent and form two transverse bands. ‘This form greatly 
resembles in its markings @. maculata, Sturm, but that species has a black vertex and 
more strongly punctured elytra. In nearly all the specimens obtained by Herr Hoge 
the two subapical spots of the elytra are wanting, so that only eleven spots are visible. 
70. Gidionychis durangoensis. 
Broadly ovate, subdepressed, testaceous, the sixth to the tenth joints of the antenne black; thorax minutely 
punctured ; scutellum black; elytra finely and closely punctured, with twelve small black spots placed 
transversely in three rows (six on each elytron), the last row oblique. 
Length 23-22 lines. 
Head impunctate, the eyes rather closely approached; antenne about half the length of the body, the lower 
five joints and the apical one also testaceous, the others black ; thorax more than twice as broad as long,
