108 PHYTOPHAGA.—SUPPLEMENT. 
space which in others is almost entirely absent, thus proving that reliance cannot 
_ always be placed on the sculpture of the elytra as a specific character; there is some- 
times a black streak placed along the suture near the apex. C. subcurvatus is somewhat 
closely allied to C. atrofasciatus, Jac. 
Cryptocephalus irroratus (p. 49). 
To the localities given, add :—Mzexico, Villa Lerdo in Durango, Colima city, Cuerna- 
vaca, Acapulco in Guerrero, Jalapa (Hége), Teapa (H. H. Smith), Temax in North 
Yucatan (Gaumer); Panama, San Miguel in the Pearl Islands (Champion). 
C. irroratus is a comparatively short and robust species, strongly narrowed posteriorly, 
with a greatly developed and somewhat gibbous thorax. The coloration seems to be 
subject to great variation. Suffrian describes the elytra as brown, with three sinuate, 
obscure, transverse, flavous bands (this does not altogether answer to the insects referred 
by me to C. irroratus), a definition I would rather give as yellow, with three more or 
less distinct brown transverse bands; these bands are frequently broken up into spots, 
but where they are more connected they separate well the yellow colour, which does 
not at all appear obsolete (as Suffrian states in his diagnosis) ; ‘the punctuation is very 
deep, widely placed, and partly irregular in both sexes, the punctures being frequently 
connected by transverse wrinkles, and there is no trace of any arrangement in pairs ; 
and frequently the first brown band is only indicated by a sutural spot. C. trroratus 
may principally be known by the very coarse and distant punctures of the elytra; the 
specimen from Panistlahuaca mentioned on p. 49 represents, I think, a closely allied 
but distinct species. 
Cryptocephalus trizonatus (p. 49). 
To the localities given, add :—Acapulco, Las Vigas, Tapachula in Chiapas (Haye), 
Atoyac in Vera Cruz (H. H. Smith), Temax in North Yucatan (Gauwmer); Brrvisu 
Honpuras, Belize (Blancaneaux) ; GuaTeMaa, El Reposo, San Gerénimo, San Joaquin 
(Champion); Costa Rica (Van Patten), Cache, Ivazu (Rogers); Panama, Volcan de 
Chiriqui, Caldera, David, Petia Blanca, Taboga I. (Champion). 
Nearly all the numerous specimens received from the State of Panama belong to a 
pale variety in which the brown bands of the elytra are separated into spots or even 
only indicated. C. trizonatus may be better described as having the elytra yellow, with 
two transverse brown bands, and the thorax with a similar band at the middle; this 
band on the thorax in some specimens is connected with the base by a narrow streak on 
each side. ‘The punctuation of the elytra also varies, the punctures being placed more 
closely in some examples than in others. C. trizonatus proves to be a widely distributed 
and common insect in Central America.
