punctures separated by about twice their own diameters, but the distinctness 

 of the rows of strial punctures somewhat obscured by irregularly spaced, ad- 

 jacent punctures; length, 5.5; width, 40. 



Beneath opaque, practically bare, metasternum and posterior coxal plates 

 with moderately strong punctures, separated by about their own diameters or 

 slightly more; abdominal sternites, except the last, with much finer punctures, 

 but with the single rows of ambulatorial setae fairly well developed. 



Genital armature of male (PI. XVI) symmetrical and somewhat resem- 

 bling that of sericea; length, z.y mm. 



$. Differs from the male by its much smaller antennal clubs, 6.5 instead 

 of 12, and smaller eyes, 7.7 instead of 9.

Serica tantula new species. 



This species bears a remarkable resemblance to delicata in size, color, 

 luster and structure. Although only a single specimen is at hand the writer 

 would judge the following slight differences to be specific: eyes smaller, 7.6 

 instead of 9; antennal club slightly shorter, 10.6 instead of 12; elytral striae less 

 sharply defined or line-like and with their punctures irregularly arranged. 



Genital armature of the male (PI. XVII) with the claspers radically dif- 

 ferent in size and shape from those in the apparently related species, delicata 

 and pusilla. 



Type: J". Lake Worth Florida (L, B. Parker), 1889. 



Serica pusilla new species. 



Probably recognizable with certainty from the two preceding species only by 

 the form of the male genital armature (PI. XVIII). The eyes and antennal 

 clubs are smaller as in tantula and the elytral striae line-like and more regu- 

 larly punctured as in delicata. The elytra seem, however, to show a stronger 

 iridescent sheen than in either delicata or pusilla.

Serica sculptilis new species. 



(^. Length, 6.5—7 mm. ; width, 3.75—4 mm. Color bay to dark chestnut, 

 surface bare and shining, entirely without bloom or iridescence and nearly 

 devoid of pubescence except for some erect, golden brown hairs on the 

 submentum, anterior coxae and femora, last sternite, pygidium and margins 

 of pronotum and elytra. 



Clypeus very broadly and feebly tumid just beyond the middle ; appear-
