472 Coleopterological Notices, IV. 



Body less robust and more oval ; ely tral intervals all narrow and with single 

 anastomosing series, except the second and third, which are wider and 

 with the punctures confused 7 streillia 



8 — Pronotal punctures very coarse, somewhat irregular and nearly as large 

 as the scutellum ; second and third elytral intervals much wider than 

 the others ; interstitial punctures small 8 callida 



9 — Prothorax large, always distinctly more than one-half as long as the 

 elytra, the median line — viewed in profile — more strongly declivous 

 toward apex ; beak generally extremely short 10 



Prothorax shorter, not more than one-half as long as the elytra, the median 

 line in profile evenly, feebly arcuate and not more strongly declivous 

 toward apex ; beak variable in length but generally longer 17 



lO — Pronotal punctures sparse, sometimes very remote 11 



Pronotal punctures close-set and even, never separated by more than their 

 own diameters at any part of the disk ; interstitial punctures generally 

 large and more or less approximate 14 



H — Interstitial punctures of the elytra fine 12 



Interstitial punctures coarse, rounded ; pronotal punctures often smaller and 

 closer anteriorly but always sparse toward base ; prosternum distinctly 

 impressed 13 



12 — Legs black or piceous-black. 



Integuments dull but smooth ; large species, intense black, the body almost 



evenly oval, strongly convex 9 Sllbovalis 



Integuments highly polished and with a more or less pronounced aeneous 

 lustre ; species moderate in size. 



Beak in the female two-thirds as long as the prothorax 10 liibrica 



Beak in the female not more than one-half as long as the prothorax. 



11 tumescens 



Legs red, the tarsi black ; pronotal punctures extremely sparse, large and 

 rather feebly impressed .....12 nitida 



13 — Black, the prothorax shorter, strongly transverse in the female; pro- 

 sternum deeply impressed 13 soluta 



Piceous ; body more narrowly oval, the prothorax longer and more rounded at 

 apex ; elytral setae longer, semi-erect and conspicuous ; beak in the male 

 not more than one-half as long as the prothorax 14 floridensis 



14 — Interstitial punctures generally broadly confused at least on the alter- 

 nate intervals, although often forming even series on some of the inter- 

 vals 15 



Interstitial punctures generally forming single series, although sometimes con- 

 fused on the third and frequently, also, on others very near the base... 16 



15 — Prothorax about as long as wide ; all the elytral intervals coarsely, con- 

 fusedly and somewhat rugosely punctured 15 subaenea 



Prothorax wider than long. 



Color dark piceous-brown throughout ; smaller species, the surface polished, 

 the elytral setae robust and subsquamiform, arranged without order and 

 very conspicuous though not dense 16 vespertina
