, r )0f) NOTES ON LACHNOSTERNA. 



the male are but slightly dissimilar, strongly resembling the fv*m type, 

 yet differing greatly in details, as a reference to the figures will readily 

 show. 



The female is rather characteristic, differing from all other of the 

 forms by having the pubic process rather slender and furcate — quite 

 different from the broadly bifid processes of arcuata, in&perata, and

37. L. ulkei Smith. 



Form robust, ovate, rufocastaneous, shining. Clypeus slightly emargi- 

 nate, the border moderately reflexed, surface rather closely punctate, 

 front more coarsely and less closely punctate. Thorax widest at base, 

 arcuatedly narrowed to the apex, margin very indistinctly crenulated, 

 with short ciliae; surface distinctly but rather irregularly and not very 

 closely punctured, with a smooth median line. Elytra more deeply and 

 densely, somewhat continently, punctured, the costse evident. Pygi- 

 dium rather finely and sparsely punctate. Metastemum densely punc- 

 tured, the hair long and dense. Abdomen shining, sparsely punctate. 

 Claws curved, the tooth median, stronger in the female. Last joint of 

 the maxillary palpi ovate, not impressed. 



Length, .85 inch, 21-22" 111 . 



Habitat. — South Carolina, Ulke; Georgia, Ulke ; Tennessee, U. S. 

 National Museum ; East Florida, Schwarz, 3 $ , 1 9 . 



Male. — Antennal club as long as the stem, abdomen flattened at 

 middle, penultimate segment with a perfectly straight, feebly elevated 

 ridge, behind which the segment is strongly depressed, making the de- 

 clivity deep and abrupt without any great elevation of the surface of 

 the ridge. The ridge is close to the margin of the segment, and in the 

 Tennessee specimen almost coincident with it. Last ventral feebly 

 concave. Inner spur of the hind tibiae two-thirds the length of the 

 outer, and stouter. 



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

 Last ventral segment feebly emarginate at apex. Pygidium more elon- 

 gate than in the male, more shining, the punctures more sharply im- 

 pressed. 



Tbis species agrees in all essentials and group characters with /»sca, 

 and with that species it has been confounded. The four specimens be- 

 fore me are very uniform in appearance, and chiefly differ habitally in 

 the paler color and the much more rugose appearance, the punctuation 

 being coarser throughout. The lateral margin of the thorax is also 

 very feebly crenulated, yet not so as to throw the species into another 

 group. The ventral character of the male gives an obvious and safe 

 distinguishing feature for that sex. In the female the somewhat 

 broader, more oval form and the coarser punctuation must suffice. 



Mr. Ulke has the male and female ; the specimen in the Museum is a 

 male. Another male specimen from eastern Florida, taken by Mr. 

 Ashmead, is in Mr. Schwarz's collection.
