Coleopterological Notices, F. 525 



S. repanda n. sp. — Rather broadly oval, polished, black, somewhat 

 piceons beneath, the legs and antennse pale ; integuments subglabrous, the 

 decumbent hairs fine and very sparse ; head and pronotum impunctate; elytra 

 strongly, sparsely punctured throughout ; metasternnra, the inner part of its 

 parapleurse and tbe first ventral plate, except toward apex, strongly but not 

 so coarsely, sparsely pnnctured. Bead vertical, moderate in size ; eyes large, 

 distant by twice their width ; antennae distant, as long as the head and pro- 

 thorax, the third joint not twice as long as wide, barely one-half as long as 

 the fourth, which is four times as long as wide and not quite as long as the 

 fifth or sixth, the latt-r equal, seventh longer, dilated and arcuate within, 

 three times as long as wide, eighth much shorter and thinner, joints of club 

 elongate, not much wider than the seventh. Prothorax three-fourths wider 

 than long, the apex barely two-fifths as wide as the base, the median lobe 

 broadly rounded ; basal angles distinctly produced and acute. Scutellum 

 minute but distinct. Elytra as long as wide, twice as long as the prothorax, a 

 little wider at basal third than at base ; apices obliquely truncate, two-thirds 

 as wide as the maximum width, the angles rather narrowly rounded ; sutural 

 and marginal striae distinct, the basal obsolete at about the middle. Mes- 

 epimera long, narrow, extending three-fifths to the coxje ; met-episterna wide, 

 the suture fine and only moderately oblique. Legs slender ; hind tarsi about 

 as long as the tibiae, the basal joint scarcely as long as the next three. Length 

 1.7 mm. ; width 1.05 mm. 



Iowa ; Missouri ; Massachusetts. 



Readily known by the punctuation and by the fact that the usual 

 post-coxal plate of the first ventral seorment is as completely obso- 

 lete as in Baeocera, the hind margin straight and anteriorly oblique 

 outwardly. The size seems to be very uniform.

 1860, p. 323. 



Broadly oval, highly polished, black, the under surface, legs and 

 antennae paler, rufous. Antennse long, the third joint one-half 

 longer than wide, enlarged at apex, scarcely one-half as long as 

 the fourth, which is between three and four times as long as wide; 

 fifth but little longer; sixth and seventh subequal, much longer, 

 nearly as long as the fourth and fifth together, the sixth feebly 

 dilated within, the seventh more strongly and arcuately so; eighth 

 shorter; club very elongate and slender, not wider than the seventh. 



impossible to modify a noun of one language by an adjective of another ; the 

 combination of letters " Pcaphisoma" in the name Scaphisowa rufida, cannot 

 therefore be Greek but must be Latin. Why we should maintain the Greek 

 gender, or any other attribute of the symbol as a Greek word, it is difl&cult to 

 understand.
