New Genera and Species of Neotropical CurcuUonidae. 203 



by the descriptions and figures, the two following species 

 should also almost certainly be referred to Exorides : — 

 Compsus lahyrinthicus Kirsch (Abh. Mus. Dresd. 1889, 

 pt. 4, p. 22), from Colombia, and C. wkymperi Olliff (Whym- 

 per's " Travels amongst the Great Andes," Suppl. Append., 

 1891, p. 63, fig.), from Ecuador. 



As at present known, the genus is confined to the moun- 

 tainous regions of Ecuador, Colombia and Venezuela, and 

 it is not imjjrobable that it will prove to be as prolific in 

 species as is Otiorrliynclius in Europe. 



In the two species of which the aedoeagus of the male 

 has been examined, E. wagneri Har. and E. ])racteritus, 

 sp. n., the median lobe is very highly chitinised, strongly 

 curved, and very much flattened dorso-ventrally, the 

 uneverted sac being completely concealed within it; the 

 struts are much compressed laterally and bisinuate as 

 seen from the side. The tegmen forms a complete ring, 

 the dorsal lobes being broad and united in their basal half, 

 and slender and divergent distally ; the strut is longer than 

 the lobes and gradually dilated at the apex. The 8th 

 ventrite is formed of two elongate transverse plates, the 

 spiculum being very stout, and strongly curved and broadly 

 laminate at its apex. 



In the case of E. ivagneri the general form of the genital 

 tube of the $ is very similar to that of ExopJitJinlmodes 

 (fig. 3), but it is not so much compressed, and the enveloping 

 membrane is even more strongly chitinised and lacks the 

 transparent transverse bar ; probably in consequence of this, 

 the vagina seems to be less chitinous and there are apparently 

 no rods; on the ventral surface there is an infolded slit 

 in the envelope, the edges of which are more chitinised in 

 the basal half, and at the a,pex the edges are armed with 

 about six stout bristles on each side of the sut; the palps 

 are well developed, but the tips are obUquely truncate, so 

 that the tactile hairs on them, which are of varying lengths, 

 project laterally outwards. The accessory gland of the 

 spermatheca is unusually long, being in one case 1*5 mm. 

 in length, the spermatheca itself (fig. 2, d) measuring only 

 0*55 mm. in both directions.
