Thus far the species seems southern ; whether it ranges farther north 

 or west, future collections must show. 



The genitalia are closely after the fusca type, but they are symmet- 

 rical. They approach most nearly perhaps in detail to grandis. The 

 female is unique, not only for the group, but for the genus. Here the 

 pubic process is distinctly double, the parts slender, parallel, and quite 

 loug. The superior plates are quite reduced, and form lateral supports 

 to the pubic process. 



38. L. quadrata Smith. 



Form oblong, parallel, rather deep brown, shining. Clypeus very 

 feebly emarginate, moderately reflexed, surface coarsely and rather 

 sparsely punctured, front more closely and more deeply punctured. 

 Thorax widest at base, arquately, but not very greatly narrowed to the 

 apex ; margin entire, with short cilia? ; surface rather sparsely and ir- 

 regularly punctate, without an obvious smooth median line. Elytra 

 closely and conflueutly punctured, the punctures tending to form longi- 

 tudinal series; costae obvious but not much elevated. Pygidium 

 sparsely and finely punctate. Abdomen shining, sparsely puuetate, the 

 last two segments more coarsely. Claws curved, the tooth strong and 

 median. Last joint of maxillary palpi ovate, not impressed. 



Length, .87 inch, 22 ,niu . 



Habitat. — Enterprise, Florida, May. 



Male. — Unknown. 



Female. — Antennal club small, much shorter than the funiculus. 

 Last ventral segment broadly emarginate at apex. 



This species is based upon a single female specimen taken by Mr. 

 Schwarz, and now in his collection. It is evidently related to fusca, and 

 agrees with it in all structural details. It is, however, well distin- 

 guished by the almost square clypeus, the punctuation of the head and 

 elytra, and by the curiously parallel form. 



The genitalia bear out the superficial characters to a remarkable ex- 

 tent, and are unique, though not as peculiar as in ulkei. The pubic 

 process is here deeply cleft at tip, but not entirely divi led, while the 

 separate tips are divaricate and pointed. The superior plates are rather 

 uniquely corrugated or folded. The discovery of the male would be 

 matter of great interest. 



39. L. politula Horn. 



Not in the Museum collection. Dr. Horn has but a single specimen 

 of uncertain locality, which he kindly allowed me to study. The geni- 

 talia very strongly resemble those of fraterna, and offer nothing note- 

 worthy. 



40. L. barda Horn. 



Not in the Museum collection.* I owe to Dr. Horn the chance to ex- 

 amine both sexes. The genitalia of the male are among the most pecnl- 



*A specimen of this species has since beeiiseub ma by Mr. Liuell for name, and this 

 is now in the Museum collection.
