100  PHYTOPHAGA.—SUPPLEMENT. 
Cryptocephalus hirtus (p. 42). 
To the Mexican locality given, add:—Ciudad in Durango (Forrer), Ventanas, Las 
Vigas (Hége), La Parada (Sallé), Xucumanatlan in Guerrero (H. H. Smith). 
Cryptocephalus alternans (p. 42). 
To the locality Mexico, add :—Near the city, Tupataro in Guanajuato (Hége). 
The two specimens obtained by Herr Hoge agree very closely with Suffrian’s 
description, and only differ from it in having the sixth and seventh rows of punctures 
(which according to Suffrian are entirely wanting) indicated by some impressions 
below the shoulder ; the short sixth row is united, however, below the shoulder with 
the seventh in a hook-like manner, In one specimen the three elytral stripes are 
strongly marked and black; in the other they are only indistinctly indicated,-so that 
the punctures between which the stripes are placed are here more distinct and blacker 
than the interstices ; in the last-mentioned example the formation of the sixth row of 
punctures is especially plain, it being obscured in the other by the black colour. The 
thorax is proportionately very short, and is better described as yellow, with a V-shaped 
central black mark. The specimen from Tupataro also has a small black spot placed 
near the lateral margin of the thorax (thus agreeing with Suffrian’s description); in the 
other this spot is enlarged into a hook-like transverse line which divides the yellow colour 
of the sides. The underside and legs also vary in the amount of black and yellow. 
Cryptocephalus semimarginatus (p. 43). 
To the Mexican locality, add :—La Parada, Etla (Salié). 
It is possible that this insect is only a variety of C. gemellatus, Suffr. 
Cryptocephalus flavonotatus (p. 43). 
To the locality Mexico, add:—Ventanas and Ciudad in Durango (Hoge). 
I refer the three specimens obtained in the State of Durango to this species; they 
might, however, be almost equally well referred to C. circumflezus, Suffr., which is 
probably nothing more than a variety of C. flavonotatus. The Ventanas specimens 
are large-sized insects (34 lines) and agree with the description of the author, with 
the exception of the colour of the legs, the femora in our examples being yellow with 
a brown central spot (not yellow with paler knees), The elytra are deeply punctured, 
and have three transverse dentate brown bands (more plainly visible when seen without 
alens). The male insect is unknown to me; Suffrian also only speaks of the female. 
The example obtained at Ciudad differs considerably from the Ventanas specimens in 
having the head and thorax entirely dark brown without yellow markings ; 
; it also has 
the thorax shorter and narrower, but similarly punctured, and the elytra marked
