AMERICAN COLEOPTERA. 139 



D. miranda, n. sp. — Yellowish testaceous. Head rugoso-punctate over 

 the entire space between the eyes. Antennae slender, pale yellowish testaceous. 

 Thorax not broader than the head, sides not sinuate near the hind 

 angles, disc sub-opaque, very finely rugoso-punctate. Elytra feebly 

 shining, slightly dilated behind, surface deeply striate, and with a 

 common median stripe cordiform at base, occupying the middle four 

 interspaces, and then gradually narrowing to the two middle inter- 

 spaces extending nearly to the apex and rounded at tip, with a 

 small oval spot near the lateral margin on a line with the tip of the 

 median stripe. Body beneath and legs pale testaceous. Length .22 

 inch ; 5.5 mm. 



This species cannot be confounded with any other in our fauna, it 

 resembling superficially scapularis, but without the lateral stripe of 

 that species. 



Occurs rather abundantly at Camp Grant, Arizona. 



APHEL.OGENIA, Chaud. 

 Mentum without epilobes and truncate at bottom of emargination 

 and not toothed. Head not constricted. Tarsi with fourth joint of 

 posterior pair either bilobed or not. The following of our species be- 

 long to this group, and are thus distinguished : 

 Thorax widely margined. 

 Head and thorax pale testaceous; body beneath pale. 



Elytra distinctly striate; and with narrow black stripes vittata. 



Elytra finely striate; stripes broad \ _ 



l Spraguei. 



Head black, thorax brownish ; abdomen black. 



Elytra with striae obsolete, ornate with spots guttula. 



Thorax narrowly margined. 

 Elytra black with two white stripes on each. 



Abdomen entirely rufous biviltatn. 



Elytra black with one white stripe on each. 



Abdomen with two apical segments red bilinoata. 



A. Spraguei, n. sp. — Head pale rufous, broadly oval, sparsely punctured; 

 palpi black. Antennas black, two basal joints piceo-rufous, and somewhat 

 paler beneath. Thorax similar in form to L. analis, Dej., pale ru- 

 fous, margin paler, surface finely wrinkled, median line finely im- 

 pressed, on each side of which near the base is a small shallow fo- 

 vea. Elytra pale rufo-testaceous with three broad black stripes uni- 

 ted in nearly their whole length and each rounded at its apex a3 

 follows : a common sutural stripe occupying the four inner intervals 

 except a small scutellar space; on each elytron an outer stripe on 

 the intervals 6 and 7, at one-third their length invading the fifth 

 and at apical third the eighth ; surface finely striate, striae obsoletely punc- 

 tured, intervals flat with finely chagrined surface. Body beneath pale rufo- 

 testaceous. Femora rufo-testaceous, at apices black, tibiae and tarsi black. 

 Fourth hind tarsal joint deeply emarginate. Length .24 inch; 6 mm.
