NO. 1337. REVISION OF THE GENUS LEPIDOPA— BENEDICT.

Fi<;. 7.— Lepidoi'A meaknsi, x 4. 



LEPIDOPA MEARNSI, new species. 



The eye-stalks are almost rectangular. The inner distal angle of the 

 stalk is much less rounded than the outer. The anterior margin i.s very 

 slightly concave. The eye-speck or cornea is situated on the side just 

 behind the rounded portion of the angle. 

 The three teeth of the front extend forward 

 to nearly the same line, the rostral tooth is, 

 however, a trifle shorter. The sinus behind 

 the eye is divided by a lobe into two nearly 

 equal parts. 



This species is more nearly related to Z. 

 richmondi than to any other. It is represented by one specimen in 

 very bad condition, the front and eye stalks are, however, intact. 



The unique type-specimen is labeled "West coast of Central 

 America." 



Type.—^o. 26171, U.S.N.M. 



LEPIDOPA RICHMONDI, new speciea. 



The character of the eyes is almost identical with L. mearnd, except 

 that the eyes of this species are proportionally slightly smaller, the 

 distal margin is more nearly straight and the inner margin is slightly 

 more arcuate. The median projection of the front is a little posterior 

 to the line of the projection of the teeth; this alters the character of 

 the sinus behind the eye and eliminates the slight sinus 

 found behind the antennula in Z. mearnsi. The mar- 

 gin between the ocular sinus and the lateral tooth of 

 the front is transverse. At first sight the effect of 

 the lateral tooth rising beyond the margin is to give 

 it the appearance of a double sinus as in Z. mearnsi, 

 but a careful examination shows that this is erroneous, 

 except in the manner that a sinus always exists at the 

 side of a spine or tooth-like projection. The carapace 

 is arcuate but slightlv flattened on the sides, forming a low ridge on the 

 median line. Longitudinally the carapace is straight. The flagellum 

 of the richmondi has 8 joints. 



Distance between lateral points of the front is 5 mm. Size of eye 



scales is 1.5 mm. by 1.5 mm. .^ii^of/.r1
