and parallel-sided. Length (cf 9) 23.0-25.0 mm.; width 12.7-13.4 



mm. Louisiana oblonga n. sp. 



A Nearly similar but more oval and more convex, the head ( 9 ) very 

 nearly half as wide as the prothorax, the latter similar but with a 

 series of fine punctures extending transversely across the median 

 part of the apex; pygidium entire; under surface and legs black, 

 with feeble violaceous lustre, the tarsi black, the central part of 

 the lower hind femoral face with a feeble pallid streak, the tibiae pale, 

 with the upper and lower surfaces black. Length (9 ) 25.5 mm.; 



width 13.6 mm. District of Columbia ponderella n. subsp. 



B Similar to ponderella, more convex and elongate-oval than in 

 oblonga and with an unusually small head, which is much less than 

 half as wide as the prothorax; coloration and sculpture above 

 nearly similar, the entire under surface deep black, with greenish 

 lustre, the tarsi throughout black, the anterior legs pale, the 

 intermediate and posterior with the femora partially pale and the 

 tibiae wholly pale, except along the upper edge; pygidium black, 

 margined beneath with flavate-brown. Female sexual characters 

 nearly as in oblonga; in ponderella the sixth ventral is nearly similar 

 but is more transversely impressed in front of the two posterior 

 tumidities. Length (9 ) 23.7 mm.; width 13.5 mm. New Jersey 



(Atlantic City) debiliceps n. subsp. 



Body as in punctata in point of size, and in ornamentation as a rule, to 

 distinctly smaller but invariably with the entire legs and tarsi pale 



testaceous 6 



6 Female with the sixth ventral not strongly impressed transversely, 

 always having two distinctly defined apical tumidities, separated 

 nearly as in punctata; hind tarsi developed as usual. Form oblong- 

 oval, convex, shining, pale yellowish-testaceous throughout above, 

 the elytra without trace of any of the usual six black dots, the under 

 surface blackish, with more or less varied metallic lustre, the hind 

 coxae pale like the legs; head and clypeus nearly as in oblonga in 

 both sexes and sexually similar, much less than half as wide as the 

 prothorax, the latter also similar, shorter than in punctata, much 

 more than twice as wide as long in both sexes and with the minute 

 sparse punctures stronger, the darker smooth sublateral spot very 

 small; scutellum more or less metallic as usual, the margins darker; 

 elytra a fourth longer than wide in both sexes, nearly as in punctata 

 but with the feebly defined series of punctures generally somewhat 

 impressed, the finer diffused punctuation rather distinct; pygidium 

 pale throughout, with transverse, anastomosing and well spaced 

 scratches, smoother apically, more convex in the male, with the 

 converging lower margins less sinuate than in the female; hind tarsi 

 three-fourths (cf) or two-thirds ( 9 ) as long as the tibiae. Length 

 (cf 9 ) 20.5-22.5 mm.; width 11.5-12.0 mm. Florida, the locality 



unrecorded. [Melolontha lutea Oliv.] lutea Oliv. 



A Nearly as in lutea but smaller, still more parallel and less convex, 

 the coloration throughout identical, except that the elytra each 

 have two spots of the usual three though very small, the humeral 

 obsolete in the type; head similar; prothorax also similar but still
