191/] Hololeptince of the United States 391 



faint median dimidiate stria; surface minutely punctulate imder high 

 magnifications. Elytra with the first dorsal stria midway between the 

 second and the margin, second stria evenly arcuate. Propygidium 

 appearing smooth on the disk (imder high magnifications extremely 

 fmelv and minutely punctulate), punctate laterally, the pmictures 

 coarse, becoming finer towards base, center, and finest but distinct 

 along the apical fourth. Pygidiimi evenly, moderately coarsely and not 

 ver\- densely punctate, the space enclosed by foiu: pimctures being equal 

 in size to one pimcture. Visible portion of dorsal segment anterior to 

 the propygidivmi coarsely and densely pimctate. Length 5.75 mm. 



Distribution, Peru and Brazil. 



^Subspecies quadridentata Fab. 



Front wdthout strioles or foveas, noticeably pimctate, more densely 

 than in the preceding; supraorbital stria extremely short, extending at 

 most less than one-third to tip of preocular spine. Pronotum pimctate, 

 more noticeably so than in the preceding. Ehtra ^^'ith the dorsal striae 

 almost as in the preceding, but the second dorsal has a slight uneven 

 sinuation opposite the apex of the first dorsal. Propygidium less 

 punctate than the preceding, the punctures more ^^'idely spaced, and 

 the apex appears smooth. Pygidium mievenly punctate, the lateral 

 punctures t\\-ice as large as in the preceding, and more dense, the space 

 enclosed by four pmictures being less than half the size of a puncture; 

 punctation finer and more distant at the center. Visible portion of the 

 segment anterior to the propygidium as in the preceding. 



Male with the anterior fossa of the thorax well marked. 



Length 5.5-5 mm. 



Distribution, Mexico. 



Subspecies floridae nov. 



Head and pronotum as in quadridentata but not more punctate than 

 typical fonn. Eh-tra \^-ith the first dorsal stria closer to the second 

 dorsal than to the margin; second dorsal as in the preceding subspecies. 

 Propygidium ^nth. the punctures distributed as in subspecies quadri- 

 dentata, but more densely punctate laterally, and sometimes XNith a 

 very few occasional punctures on the disk. Pygidium with the 

 punctures spaced as distantly as in the typical subspecies, but dimin- 

 ishing in size towards the center as in quadridentata. Visible portion of 

 the segment anterior to the propygidium -^A-ith slightly larger but fewer 

 punctures than the preceding. 



IMale with the anterior fossa of the thorax well developed, and deep. 



Length 5-4.25 mm. 13 males, 14 females.
