and with fine punctures. Ventral segments of abdomen rather densely punc- 

 tate and rugulose ; last segment sparsely punctate and rather smooth ; pubes- 

 cence moderately dense. Length 6.25 mm. 



Fort Defiance, Arizona. 



The type is in the Museum collection, others are in the collections 

 of Messrs. Win. T. Davis and Ernest Shoemaker, to whom I am in- 

 debted for specimens. 



Following Dr. Horn's table this species would be associated with 

 his crenicomis, from which it differs in having stouter and shorter 

 antennae, the surface of the head smooth and even, the frontal tubercles 

 obliterated and the decidedly black underside. The sculpture of the 

 last ventral segment is in most of the species generally a little sparser 

 than on the other segments but in this species the sculpture of the last 

 ventral contrasts from that of the other segments, being nearly smooth 

 and the punctuation sparse. 



Disonycha lodingi new species. 



Form and coloration almost as in caroliniana. Head smooth, shining, 

 with a few punctures in a fovea-like impression near each eye ; frontal tuber- 

 cles distinct ; antennae rather narrow and elongate, reaching to or a little be- 

 yond middle of elytra, third joint longer than second, but not twice as long, 

 fourth longer than second and third together, from the fifth gradually decreas- 

 ing in length. Prothorax fully twice as wide as long ; sides gradually narrow- 

 ing to apex; basal angles distinct but obtuse; apical angles oblique; surface 

 smooth and shining. Elytra at base scarcely wider than the prothorax at base, 

 sides arcuate ; surface minutely reticulate with minute, obsolete, sparse punc- 

 tures. Ventral segments of abdomen densely punctate and pubescent. Length 

 6 mm. 



DelchampSj Alabama (Ff. P. Loding). 



In form and coloration this species looks at first sight almost ex- 

 actly as caroliniana but the antennae are much longer with narrower 

 joints and the ventral segments are more densely punctate than in that 

 species. 



Disonycha alabamse new species. 



Oblong oval ; above flavous : labrum, antennae except the first three joints, 

 scutellum, a sutural, discal and marginal vitta black ; the discal vitta broad 

 but placed nearer the lateral margin than the suture, and much wider than the 

 outer pale space but much narrower than the inner pale space. Below pale, 

 except the tibiae near apex and tarsi black.
