3Iale. — Prosternum densely, coarsely punctured and slightly pubescent between 

 the coxae, more sparsely punctured in front ; anterior tibiae (226) arcuate and 

 with a dilatation at apical third ; middle tibiae straight, slightly thickened at tip, 

 posterior tibia straight; last ventral segment (224) with a shallow, semi-circular 

 emargination, the last dorsal sparsely punctate, vaguely emarginate at tip. 



Female. — Prosternum coarsely, sparsely punctate; anterior tibia slightly arcu- 

 ate, the middle and posterior straight ; last ventral segment (225) very slightly 

 notched at tip, longer than in the male, the sides slightly sinuate ; last dorsal 

 sparsely punctate, entire. 



This species is very inconspicuous and might readily be mistaken 

 for p mi /la. In the typical specimens the elytra show no traces of 

 more densely punctured foveas, although there are slight depressions 

 where they should be, but in some specimens I have examined the 

 foveie are nearly as plain as in puslMa, thereby increasing the resem- 

 blance, at the same time the elytral punctuation is coarser. 

 Occurs in Kansas, Nebraska, Nevada, Texas and Arizona. 



46. C clirysoela Illig. — Form moderately broad, not depressed, color pur- 

 plish black, or faintly cupreous ; elytra with golden to greenish spots, usually 

 four on each side, the posterior two often transversely confluent ; body beneath 

 dark bronze ; antennae gradually more slender to tip, cupreous in both sexes, the 

 third joint a little longer than the next two; front slightly convex, coarsely 

 punctured, an arcuate carina above joining the occipital carina, greenish % or 

 bronze 9 ! clypeus (228) triangularly emarginate at middle, arcuate each side; 

 thorax twice as wide as long, anterior angles obliquely truncate, the sides slightly 

 sinuous ; disc moderately convex, without depressions, punctuation coarse, 

 sparser at middle, dense near the sides; elytra wider than the thorax, slightly 

 broader behind the middle, arcuately narrowing at apical third, the margin ser- 

 rulate, the apices obtuse ; disc moderately convex, without trace of costae, basal 

 fovea moderately deep, golden or green, this color often reaching the humeri, a 

 distinctly impressed fovea near the middle of each elytron and a spot opposite on 

 the lateral margin, these often united, one-third from apex two spots, these often 

 transverely confluent ; surface coarsely but not closely punctate ; body beneath 

 with very large punctures, the ventral segments without callosities, the margin 

 of the last ventral entire ; prosternum faintly lobed in front ; anterior femur with 

 a moderate, acute tooth, not serrulate. Length .28 - .32 inch ; 7 - 8 mm. ( Fig. 227. ) 



ilnle. — Prosternum very coarsely punctate, a uarrow elevated median line ; an- 

 terior tibia (231) arcuate, a very slight dilatation near the tip; middle tibia 

 slightly arcuate, the posterior straight; last ventral segment (229) with a broad, 

 but shallow, arcuate emargination, the angles distinct ; last dorsal coarsely punc- 

 tured, the apex entire. 



Female. — Prosternum as in the male ; anterior and middle tibiae slightly arcuate, 

 posterior straight ; last ventral (230) sinuately truncate, the angles acute, a sub- 

 apical serrulate ridge ; last dorsal as in the male. 



This species and scitula are closely related, more so in description 

 than in facies. The present species has a broader thorax, and is in 

 fact broader generally, the punctuation is less coarse and the elytral 

 spots of difll^rent appearance and form.
