 Fig. 20 

 Oedionychis ulkei Horn, Trans. Amer. Ent. Soc, vol. 16, 1889, p. 188. 



Oval, convex, moderately shining, yellowish or appearing brown 

 because of the usually wide reddish brown markings, a broad fascia 

 across pronotum and wide sutural vitta and vitta in middle of each 

 elytron. Antennae nearly half as long as body, stout, reddish brown, 

 three basal joints paler, third and fourth joints subequal. Head 

 reddish brown, moderately coarsely punctate, middle of occiput 

 usually smooth and shining; median groove rather indistinct, inter- 

 ocular space more than half width of head. Pronotum about three 

 times as wide as long, convex, narrowed anteriorly, with narrow 

 explanate margin; finely but distinctly punctate; a wide reddish 

 brown fascia. Scutellum reddish brown or piceous. Elytra rounded 

 oblong, convex, sides nearly parallel ; humeral prominences rounded, 

 with faint depression within, margin very na!rrow; punctation 

 coarse but shallow ; a common entire sutural vitta reddish brown or 

 piceous and of varying width, and a usually broad median vitta on 

 each elytron, not quite reaching apex, occasionally uniting at some 

 points below middle with sutural vitta. Body beneath reddish brown, 

 finely pubescent, epipleura more or less piceous. 



Length. — 4 to 5.5 mm. ; width 2 to 3 mm. 



Type locality. — Florida. 



Distribution. — Florida. 



This species is closely allied to miniata, the only differences being 

 in the length of the third and fourth antennal joints and the gener- 

 ally smaller size and more rounded outline. The punctation of 

 the head is usuall}'^ sparser. In some instances these differences do 

 not appear sharply distinctive, and it is questionable whether Oe. 

 ulkei is not a variety of miniata. 



W. S. Blatchley found this species on flowers of Desmotha^n/nus 

 and other Ericaceae.

Elongate oval, moderately shining, with dark reddish brown head 

 and pronotum and dark blue elytra. Antennae slender, half length 

 of body, reddish brown, basal joints slightly paler, third and fourth 

 joints about equal. Head finely punctate, median groove indistinct, 

 interocular space less than half width of head, eyes large. Pronotum 

 a little over twice as wide as long, feebly convex, narrowed arcuately
