I have hesitated much as to whether this name should be applied to the species at 
present under consideration or to C. puncticollis. Reitter’s description is applicable 
to both; but as he gives ©. planus a length of 14 millim., and I have not seen an 
example of C. puncticollis longer than 12 millim., I have decided to apply the name 
to the species which meets the requirement in size as well as other particulars. 
C. planus is remarkable for the length of the antenne, which in the best developed 
example before me attain 11 millim. in length, though in another they are only about 
8 millim. long. Independently of this character, C. planus is distinguished from all 
our other species by the less scanty punctuation of the ventral segments, and by the 
curious impressed line on the last ventral plate being situate farther from the hind 
margin, and by its not being angulate in the middle. 
Of the four specimens before me, three are from Capetillo and one from Jalapa: two 
of those from the former locality have the antenne about 11 millim. long, while in 
the example from Jalapa they are only about 8 millim.; the third specimen from 
Capetillo has the antenne much mutilated, but from what remains I consider they 
would be, if perfect, of about the same length as the Jalapa example. Whether this 
difference in the length of the antenne be sexual or not, I am quite unable to say. 
8. Catogenus puncticollis, sp.n. (Tab. XVI. fig. 3.) 
Depressus, nitidus, piceo-brunneus vel ferrugineus ; capite prothoraceque evidenter punctatis, illo vertice 
canaliculato-foveolato, hoc deplanato, lateribus posterius rectis; elytris leviter striatis, striis quinto 
sextoque bene discretis, ad basin summum conjunctis ; abdomine parce punctato. 
Long. corp. 10-12, antennarum 43-6 millim. 
Hab. Mexico, Jalapa, Huitzo (Hoge); GUATEMALA, Capetillo, Panajachel (Champion). 
Thorax with the anterior angles rectangular, the lateral margin extending to the 
front; the sides are scarcely curvate, but behind the middle are abruptly narrowed, 
and then before the base become quite straight, the hind angles being very conspicuous, 
plicate; the punctuation is very distinct, but becomes quite fine at the sides. The 
elytra are depressed, the striz moderately deep, the interstices flat ; the fifth stria is 
quite distinct throughout its length, and the sixth is but little less so. There is a 
short channel on the mesosternum, and the ventral segments are distinctly though 
sparingly punctate. 
Mr. Champion met with a series of nine examples at Capetillo; the three Mexican 
exponents have the striz on the elytra a little deeper. 
The North-American C. rufus (Fabr.) is extremely similar to C. puncticollis, but has 
the head canaliculate.
