The three preceding have the propygidium more convex 

 and longer in proportion to its width than the following sub- 

 species : 



Subspecies minor no v. 



Front, and pronotum punctulate as in typical subspecies. Supra- 

 orbital stria extremely short, basal, usually a single puncture or 

 punctiform. Elytra with the dorsal stria as in the preceding subspecies. 

 Propygidium punctate as in the preceding laterally, but with some of 

 the discal punctures more enlarged than in the preceding forms. 

 P^^gidium as in the preceding subspecies. 



Male with the anterior fossa of the thorax very shallow and poorly 

 developed. Both sexes with anterior angles of the pronotum depressed. 



Length 4.25-3.25 mm. G d^cT, 16 9 9 . 



Type, allotype and paratypes in my collection. 



Distribution, Enterprise, Indian River, Florida and North 

 Carolina. 



This sub-species has the propygidium more flattened and 

 shorter in proportion to its width than any of the preceding 

 subspecies. There is a gradual decrease in the size of these 

 s\ihs^ec\Qs; platysma, quadridentata and floridce are close together 

 in size, and progressively smaller; minor is very much smaller. 

 The measurements given above for floridce and minor do not 

 seem to show this, but when the average size of a series is taken 

 it is very distinct. The average size of my series of floridce is 

 4.75 mm., while the average size of minor is 4.2 mm. 



Subspecies floridae var. striatifera nov. 



More narrowly oval than typical florida. Supraorbital stria mod- 

 erately well defined but short. Marginal stria of thorax entire, with a 

 very shallow semi-circular sinuation just before the middle; under this 

 sinuation and between the marginal stria and the margin lies a short 

 stria. Propygidium and pygidium as in floridcs. 



Length 4.75 mm. Type in my collection. 



Distribution, Florida. 



This species is very variable in the number and spacing of 

 the teeth on the lower crests of the hind and intermediate 

 tibiae; the commoner forms have this crest with two closely 

 approximated teeth on the middle tibiae, and one tooth on 

 the hind tibi«, or two moderately widely spaced teeth on the 

 middle tibiae and two closely approximated teeth on the hind 

 tibiae; less often we find the spaced teeth of the middle tibiae
