A New Species of Amphotis. 



By Hy. Ulke. 



The discovery of a new species of Amphotis induced not only a 

 comparison of the two species now found in our country, but also of the 

 two genera Soronia and Amphotis, which have been united by Dr. Horn 

 under the name of the first genus. 



The separation of the two genera 

 was chiefly based upon the difference 

 in the antennal grooves, which are 

 convergent in Soronia and parallel 

 in Amphotis. 



Soronia undulata however repre- 

 sents an intermediate form and makes 

 this character less important. 



The structural characters which 

 eventually may lead to the re- 

 establishment of Amphotis are found 

 in the mentum, antennae and elytra. 

 The costate opaque elytra are so characteristic, that I recognized the 

 genus at once — when I first discovered Amphotis ulkei — by the excellent 

 figure given by Du Val. 



Amphotis schwarzii, n. sp. 



Elongate oval, light brown, opaque. Head densely punctured and sparsely 

 covered with short yellow setae. Antennae less slender, club abrupt. Thorax twice 

 as wide as the length at middle, narrowed in front, apex deeply emarginate, base bi- 

 sinuate, sides arcuate, broadly explanate and the margin slightly reflexed, hind angles 

 rectangular, densely punctured and sparsely covered with short yellow setae. Elytra 

 as wide at the base as the thorax, humeral angles slightly dentiform, sides broadly 

 reflexed, disc somewhat depressed, with a sutural, a short scutellar, five discal costae 

 and two additional smaller ones between the fifth costa and the margin. The irregular 

 coarse punctures of the intervals and the summits of the costae bear short yellow 

 setae. The inflexed portion of the margin is more finely punctured. Body beneath 

 is equably punctured, punctures with short yellow setae. — Length 5 — 6 mm. 



This species is very much like A. ulkei, but the uniform, pale brown 

 color and the additional ridges in the inflexed portion of the elytral margin 

 will at once distinguish it. 



I take great pleasure in dedicating this interesting addition to our 

 fauna to my friend, Mr. E. A. Schwarz of Washington, who is so well 

 known to every scientific Entomologist of the country. 



It would be interesting to know the habits of this new species. Mr. 

 Schwarz collected it in numbers on the beach near Fortress Monroe, Va., 

 where they had been washed ashore.
