CIS. 221 
Punctuation very fine, not evident; the prothorax with some ashy pubescence; the 
elytra have a very short golden pruinose pile. Head with the clypeus raised at the 
margin from one eye to the other. In the male this is notched in front in the middle, 
and with a double sinuation on each side, so that six blunt teeth are formed in the 
margin. The thorax quite covers the head, when viewed perpendicularly; in the male 
two projecting tubercles are present on the front; in the female it is quite plain. 
The figure is taken from a male Zapote example. 
I have retained the MS. name which this insect bears in Sallé’s collection. 
3. Cis bubalus. 
Cis bubalus, Reitter, Mittheil. d. Miinch. ent. Ver. 1878, p. 32°. 
Breviter oblongus, subparallelus, nigro-piceus, nitidus, antennis rufis, elytris pruinosis. Long. 23 
millim. ¢ Q. 
Mas. Prothorace antice acute bituberculato, clypeo margine obtuse quadridentato. 
Femina. Prothorace mutico, clypeo margine leviter reflexo.

Zunil, San Juan, Chacoj, El Tumbador, Zapote (Champion). 
Very closely allied to C. fasciatus, but usually black or pitchy, without any trace of 
a fascia. ‘The thorax is as wide as the elytra, with the sides parallel in the male, the 
front a little narrowed in the female; and the projecting tooth-like tubercles are more 
prominent than in C. fasciatus. ‘The very short pruinose pile of the elytra is thicker, 
and is of a golden shining appearance; the punctuation fine, but close and distinct. A 
large number of this were taken, especially at San Juan in Vera Paz. The specimens 
from Oaxaca are immature. 
I have no doubt from his description that this is the Cis bubalus of Reitter, whose 
diagnosis of the male is:—‘“ Mas. Clypeus apice sublaminatus, lamina trisinuata, obtuse 
quadridentata; thoracis margine antico bidentato.” 
4. Cis bisbidens. (Tab. X. fig. 24, ¢ .) 
Oblongus, subcylindricus, nigro-piceus, parum nitidus, crebre punctatus. Long. 3 millim. ¢ 9. 
Mas. Capite antice bidentatus, prothorace spinis duabus acutis, antice subrecte productis. 
Femina. Prothorace antice obsolete bituberculato. 
Hab. Mexico, Orizaba, Puebla (Sallé). 
Of the same size and in form not unlike Cis bubalus; the males are readily recog- 
nized by the two acute thorn-like productions from the thorax, and by the ¢wo laminar 
elevations of the margin of the head in front. Of four specimens there are two males 
and one female from Orizaba, and one female, which cannot certainly be identified, but 
is probably of the same species, from Puebla. It will probably be found that the 
females of this species have less bulky thoraces than Cis bubalws, with which they
