Length. — 4 to 5.5 mm. ; width 2 to 2.5 mm. 



Type locality. — PennsylYania. 



Distributi&ti. — Massachusetts, western New York, Pennsylvania, 

 Indiana, Iowa, Michigan, Missouri, Mississippi, Louisiana, Georgia, 

 Florida, and Texas. 



This is a most variably marked species, to be distinguished by 

 its large, closely set eyes, its rather short and broad pronotum, and 

 broadly oblong elytra. It is to be separated from the banded forms 

 of ohsidiana var. flava by its relatively larger size and coarser punc- 

 tation. Specimens examined from Florida present an unusually 

 varied pattern in elytral markings. They are all of the same pro- 

 portions and have the distinguishing character — the large, closely 

 set eyes. 



W. S. Blatchley collected this species at Florida on some species 

 of Ericaceae. 



34. OEDIONYCHIS DURANGOENSIS Jacoby 



Fig. 46 



Oedionychis durangoensis Jacoby, Biol. Cent.-Amer., Coleopt., vol. 6, pt. 1^ 

 Supplement, 1892, p. 318. 



Broadly oval, feebly shining, yellow brown or drab, with five or 

 six small black spots on each elytron. Antennae slender, half as 

 long as body, third joint slightly shorter than fourth, first four and 

 part of fifth basal joints and terminal joint paler. Head faintly 

 punctate, more coarsely about eyes, with occiput nearly smooth; 

 median groove indistinct, interocular space not half so wide as head ; 

 eyes large. Pronotum nearly three times as wide as long, with 

 moderately wide explanate margin, arcuately narrowed anteriorly,, 

 very faintly punctate. Scutellum small, shining black. Elytra long 

 and broadly oval, with wide, sometimes slightly reflexed explanate 

 margin, and with basal callosities near suture and humeral promi- 

 nences forming sulcus; finely and densely punctate; six small black 

 spots on each elytron placed in two longitudinal rows: First row 

 with spot on humerus, second near lateral margin at basal fourth, 

 third near lateral margin slightly below the middle; second row 

 with first spot in middle of elytron at base, second near suture at 

 basal third, and third near suture, slightly below middle, in some 

 specimens spots in middle at base missing. Body beneath yellowish 

 brown, finely pubescent, epipleura pale. 



Length. — 5 to 6.2 mm. ; width 3 to 3.5 mm. 



Type locality. — Ventanas. Durango, Mexico. 



Distribution. — ^Arizona. 



This species is not closely related to any other North American 

 Oedionychis. It is one of the largest of its group, Oedionychis 

 scalaris alone approaching it in size. It is, however, quite distinct
