LEPIDOPA VENUSTA Stimpson. 



Lepidopa venusta Stimpson, Proc. Acad. Nat. Sci. Phila., 1858, p. 230 (without 



description); Ann. Lye. Nat. Hist, of New York, VII, p. 79. 

 Lepidops venusta Mieks, Jour, of Linn. Soc. of London, XIV, p. 332. 



Eyes ()bloni>-, broadest a})out the posterior third, narrowing- toward 

 the cornea, which is terminal and very small, 

 barely visible from above. From below, under a 

 lens, it is shown as a black speck with a little 

 dark streak running to the })ottom of the peduncle. 

 The ocular sinus is separated from the spine 

 behind the antenna by a slight lobe in all speci- 

 mens. Between the spine and the antero-lateral 

 angle the outline is slightl}^ concave. The front 

 and lateral projections are equally advanced. 



Length of carapace of largest specimen, 11 

 mm.; breadth, 14 mm Savanilla, U. S. Colom- 

 bia; collected by the U. S. Fish Commission steamer Albatross; three 

 specimens. 



LEPIDOPA WEBSTERI, new species. 



Lepidopa venusta, Kingsley, Proc. Acad. Nat. Sci. Phila. for 1879 (Part pub. 

 March 9, 1880), p. 410. 



In comparing the single specimen referred to by Mr. Kingsley with 

 Lepidopa venusta, it is found to be very closely related, but yet dis- 

 tinct. It differs in having the lateral teeth of the front closer to the 

 rostral tooth, while in Z. venusta they are closer to the spines of the 

 antero-lateral angles; the lateral teeth of L. icehsteri 

 are also more produced, and the lobe between the base 

 of the rostral tooth and the lateral teeth has almost dis- 

 appeared from this species, while prominent in L. ven- 

 usta. The eye stalks are in a general way only like 

 those of L. venusta; they are not so long in proportion 

 and are not contracted as much near the apex. The 

 specimen can hardly be said to have an eye speck; a 

 dark line on the lower surface may serve to distinguish light from 

 darkness. 



The color of this species, as L. venusta, also is iridescent.* 



The carapace is" 7 mm. in length and 9 mm. in breadth. 



Named for the collector, Prof. H. E. Webster. 



The type belongs to Union University, Schenectady, New York, 

 and was taken on the beach near Fort Macon, North Carolina. 



LEPIDOPA MYOPS Stimpson. 



Lepidops myops Stimpson, Ann. Lye. Nat. Hist. New York, VII, 1862, p. 241.— 

 MiERs, Jour, of the Linn. Soc. of London, Zool., XIV, 1879, p. 333, pi. v, 

 fig. 16. 



The eyes are broad and very broadly rounded at both angles, the 

 inner distal angle is, however, more evenly rounded than the outer,.
