Mr. James A. G. Rehn at one time regarded Z. cnientata (Blanchard) 

 as being distinct from tarsata (see Proc. Acad. Nat. Sci. Phil., LIX, 

 p. 175, 1907). More recently, however, he thinks that they only 

 represent geographic races, or merely environmental phases of a 

 single species. (Trans. Am. Ent. Soc, XLIV^ p. 202, 1918.)

77. Ophthalmolampis geniculapicta sp. nov. 



Among the described species, as shown by the synoptical key pre- 

 pared by me and published in the Annals, Vol. VIII, pp. 476-477, 

 this form is most nearly related to 0. genicidata Stal. It is a medium- 

 sized insect with two narrow, interrupted, pale longitudinal lines on 

 the sides of the pronotum, the one above bounding the disc on its 

 outer margin, and the other located about two-thirds of the distance 

 towards the lower margin. Hind femora with the genicular black, 

 ornamented by three large orange-red maculae, two of which are 

 situated on the sides and the other above. The hind tibiae at their 

 base also are provided with a prominent macula of the same color. 



Head of moderate size, about as wide as the front edge of the 

 pronotum, into which it fits almost to the eyes; the occiput but little, 

 if any, elevated, very coarsely and deeply pitted or punctured, as are 

 the front, cheeks, pronotum, and sides of both the meso- and meta- 

 thorax. Verte.x narrow, depressed between the upper portion of the 

 prominent eyes, but little wider than one-half the diameter of the 

 basal antennal joint, the fastigium widely and roundly sulcate, the 

 frontal costa not prominent, as wide above the antennae as the fasti- 

 gium, not sulcate, but coarsely pitted, a little narrowing anteriorly 

 and terminating at the ocellus, which is located at a point a little in 

 advance of a line drawn across the front at the lower edge of the 

 antennal sockets. Antennae rather slender, about as long as the hind 

 femora, in nowise ensiform, but with all the segments slightly flattened.
