102 PHYTOPHAGA.—SUPPLEMENT. 
C. dissolutus closely resembles C. flavonotatus, and, to a less degree, C. difficilis ; it 
seems, however, to differ sufficiently from both to justify its separation, if characters 
derived from colour and elytral punctuation are considered of any specific value. It 
will be sufficient to point out the differences between the present and the allied species:— 
In C. dissolutus the thorax is nearly impunctate on the disc, and has a fulvous lozenge- 
shaped spot (this spot in the Guatemalan specimen is almost obsolete). The elytra 
have only two bands (each broken up into two spots), and a small spot at the apex 
placed between the third and fourth, and the seventh and eighth rows ; these rows 
are, as usual, connected posteriorly, as are also the shorter fifth and sixth ; the seventh 
and eighth rows are only distinct anteriorly near the shoulder, and below this they are 
connected by a few transversely placed punctures which surround a smooth transverse 
space. The underside and legs are entirely fulvous. Two specimens, both females. 
6 (c). Cryptocephalus separatus. 
Obscure flavous, the antenne (the basal joints excepted) black; thorax impunctate ; elytra flavous, strongly 
punctate-striate, the stric not interrupted by a raised space, a spot on the shoulder, an angular transverse 
band at the base, another band below the middle, and a spot at the apex, dark brown. 
Length 23 lines. 
2. Head depressed, finely punctured, the middle stained with fulvous; antenne two thirds the length of the 
body, black, the lower four joints fulvous; thorax twice as broad as long, widened at the middle, 
the sides rounded, the surface entirely impunctate, obscure flavous ; scutellum flavous, its apex truncate ; 
elytra robust, cylindrical and parallel, the punctured strie strong and regular, the fifth and sixth rows 
abbreviated and connected before the apex, the seventh row represented anteriorly by a few remotely- 
placed punctures only, but complete posteriorly, and there joined to the eighth row, the interstices 
finely transversely rugose, the ground-colour flavous (brighter than that of the thorax), the extreme 
basal margin black, a spot on the shoulder, a transverse band of angulate shape at the base, a similarly 
shaped band below the middle extending to the lateral margin, an obscure spot at the junction of the 
strie near the apex, and the extreme lateral margin posteriorly, dark brown; underside obscure flavous, 
the breast darker and clothed with yellowish hairs ; legs obscure fulvous. 
Hab. Mexico, Xucumanatlan in Guerrero (ZZ. H. Smith). 
C. separatus somewhat resembles C. sordidus in coloration, but differs from that 
species in having the dark bands of the elytra strongly marked, and their punctuation 
finer and differently arranged ; there is an entire absence of a transversely raised space 
and the rows of punctures are nearly all distinct. C. dissolutus is a still more closely 
allied species of almost exactly similar markings, but that insect has the lateral rows 
of punctures on the elytra interrupted by a comparatively broad impunctate space, and 
the interspaces smooth (not finely rugose); it is, however, possible that C. separatus 
may only be a local form of C. dissolutus. <A single female example, captured in July 
1888. 
Cryptocephalus plagiatus (p. 45).
