74 MEMOIRS ON THE COLEOPTERA 



more abbreviated, nearly two and one-half times as wide as long; 

 elytra similar but more depressed; pygidium still more sculpture- 

 less toward apex and with the sides more sinuate. Length (cf) 

 20. o mm.; width 10.7 mm. Florida (Jacksonville). 



brevicollis n. subsp. 



B Nearly as in lutea and with similar convex surface and short 

 transverse prothorax, which is rather more than twice as wide as 

 long, but with the usual three black spots on each elytron, which 

 are however smaller as a rule than in punclata; under surface 

 blackish, largely pale peripherally throughout, the legs and pygid- 

 ium similarly invariably pale testaceous throughout. Length 

 (cf 9 ) 20.0-23.3 mm.; width 10.9-13.0 mm. Virginia to Mis- 

 sissippi. Abundant pallidipes n. subsp. 



C Form, size and coloration throughout nearly as in lutea but always 

 having the three black spots on each elytron well developed; 

 head notably smaller, the clypeus (9) more narrowly parabolic; 

 prothorax relatively narrower and less transverse, distinctly 

 narrower than the elytra and not quite twice as wide as long; 

 elytra nearly similar in form and sculpture; pygidium in both 

 sexes more narrowly rounded at apex, especially in the female, 

 the latter sex having the apical concavity of the sixth ventral 

 nearly as in lutea, small, deep and almost parallel-sided; hind tibiae 

 (9 ) shorter than usual, not as long as the femora, the terminal 

 spurs subequal. Length (cf 9 ) 20.0-21.7 mm.; width 11.3-12.2 



mm. Texas (Horristo). Four examples texensis n. subsp. 



D Form and coloration nearly as in texensis but a little larger, the 

 head rather better developed and nearly half as wide as the pro- 

 thorax, which is similarly less than twice as wide as long and evi- 

 dently narrower than the elytra, the latter about a fourth longer 

 than wide and with vestiges of impressed striation more evident; 

 hind legs normal, the tibiae as long as the femora, the spurs very 

 unequal in size; female with the apical cavity of the sixth ventral 

 wider and shallower, its sides strongly anteriorly converging. 

 Length (cf 9 ) 22.5 mm.; width 12.0-12.6 mm. New York 

 (Peekskill). The male associated with the female type bears no 

 locality label, but appears to be identical specifically. 



hudsonica n. subsp. 



Female with the sixth ventral strongly impressed transversely in about 

 anterior half, the evenly elevated posterior part with a small median 

 excavation, the lateral transverse parts even and not tumidiform; 

 tarsi much smaller and more slender than usual. Form oblong, 

 moderately convex, colored throughout as in lutea but with three 

 well developed black dots on each elytron; head rather small, much 

 less than half as wide as the prothorax, formed nearly as in lutea, 

 as is also the prothorax, which is short and much more than 

 twice as wide as long; elytra in form and sculpture nearly as in lutea 

 and not distinctly wider than the prothorax; pygidium nearly similar; 

 legs rather shorter and less stout; hind coxae shorter, the outer pos- 

 terior angle more produced posteriorly. Length (9) 20.5 mm.; 

 width 11.3 mm. New York (Peekskill) tarsalis n. sp.
