Dr. Guy A. K. Marshall on 



marking behind the middle, the apex of the angle being on the suture 

 at the top of the declivity; the legs as in E. consohrinus. 



In general form and structure this species is also closely related 

 to E. crassicornis Kirsch, but the scape of the antennae is more slender 

 and less compressed ; the larger punctures on the pronotum are 

 equally numerous, but distinctly less coarse ; the punctures on the 

 elytra are more quadrate, more narrowly separated and consequently 

 more numerous, those in stria 1 between the two bands numbering 

 12-15 in the ^ {crassicornis, 8-9) and 15-17 in the $ {crassicornis,' 

 10-11) ; and the spermatheca of the 2 differs in shape (fig. 2, a). 



Length, 15-20 mm. ; breadth, 6-5-9 mm. 



Ecuador : S. Javier (type) ; Paramba, 3500 ft. {Rosen- 

 berg) ; Lita, 3000 ft. {Rosenberg). 



Described from twenty-two specimens. 



Fig. 3. — Fema'e genitalia of Exophthalmode-s parentheticvs, sp. n., lateral 

 view : a, vaginal palps ; b, membranous lamina ; c, chitinous strips 

 in walls of a agina. 



In all tbese species of Exophthalmodes the vagina of the 

 $ is strongly compressed laterally, from 3-5 to 4 mm. long, 

 and strengthened by several chitinous strips in its walls 

 (" Seitenstiicke " of Stein), being further supported in 

 oviposition by the enveloping membrane, which is strongly 

 chitinised on the appressed sides for from two-thirds to 

 four-fifths the length of the vagina; and, as is often the 

 case, this chitinous envelope is divided transversely about 

 the middle by a transparent bar (fig. 3). In the apical 

 half of the envelope on its ventral side is a membranous 

 lamina (v/ith only its lower edge chitinised) which can be 

 slightly exserted downwards from between the two chitinous 

 plates, like the partly-opened blade of a pocket-knife. 

 The terminal palps are well developed, being 0-36 mm. long, 

 with a number of hairs at the tip.
