190 Dr. Guy A. K. Marshall on 



that the error has arisen from the fact that Mr. Pierce must 

 have had before him not quadrivittatus, but sommeri Kosen.^, 

 a true Diaprepes that has an extraordinary superficial 

 resemblance to it. 



The attempt to discriminate Diaprepes from Exophthal- 

 modes by means of the prothoracic vibrissae is not satis- 

 factory, because these setae are very variable in develop- 

 ment and in some species are very difficult to detect. 

 There is a much better character in the antennal funicle, 

 the second joint being much longer than the first in 

 Diaprepes and about equal to it in Exophthalmodes. 



Exophthalmodes consobrinus, sp. n. (Plate III, fig. 10.) 



(J$. Integument black, covered densely beneath and much more 

 sparsely above with glistening blue-green scales ; the prothorax with 

 two denser dorsal stripes of similar scaling, which are usually con- 

 tinued on the head along the inner edge of the eyes to the apex of the 

 rostrum ; the elytra with a broad ring round the shoulder formed 

 of pale greenish white scales dusted with yellow powdering, and a 

 broad, slightly curved, transverse band of similar scales across 

 the top of the declivity, both these markings coalescing laterally 

 with a pale marginal stripe; the prosternum greenish white \vith 

 yellow powdering; the legs with fairly dense green scaling, the 

 femora with bare black dots round the setae. 



Head with sparse shallow punctures and a deep frontal fovea. 

 Rostrum nearly as long as the pronotum, parallel- sided in the basal 

 half, thence dilated to the apex ; a broad bare median stripe, which 

 is very shiny and sparsely and minutely pvmctate, and on each side 

 a short deep sulcus ; the interantennal area rather steeply declivous 

 and broadly excavated ; the genae with a very deep, strongly curved 

 furrow which extends right up to the lower angle of the eye. 

 Antennae with fairly dense, narrow, pale green scales, sometimes 

 mingled with blackish ones; the scape extending beyond the eye, 

 gradually thickened at the apex, set with short blackish setae which 

 are erect on the lower anterior face and recumbent elsewhere; 

 the joints of the funicle in order of length: (1, 2), 3, 4, (5, 6, 7). 

 Prothorax a little broader than long, subparallel- sided from the base 

 to the middle, then roundly narrowed to the apex ; the basal margin 

 shallowly bisinuate, the apex truncate; the dorsum very shiny, 

 with fine shallow punctures each containing a scale, and a few 

 larger scattered punctures (from 15 to 20) in the median area between 

 the two stripes, the lateral areas beyond the stripes being closely 

 set with coarse punctures. Scutellum trapezoidal, a little longer
