CRYPTOCEPHALUS. 47 



and two following striae interrupted below the shoulder; each elytron with nine small black spots 

 (1, 4, 2, 2). 

 Length 2f lines. 



Hab. Mexico, Cordova {Salle), Jalapa 1 , Vera Cruz, Oaxaca. 



This easily recognizable species does not seem to be a rare one, and is contained in 

 most collections ; it has not been received as yet from Guatemala or other parts to my 

 knowledge. 



I cannot at all agree with Suffrian's definition of the elytral punctuation in this 

 and several other species. In counting the number of striae on each elytron, I find 

 in the present insect but nine rows (the short sutural one not included) ; the eighth 

 row, according to Suftrian, is absent and only indicated by an impression of the 

 ninth (!), which I am at a loss to understand, as it conveys no meaning. This author 

 further says that the fifth and eighth striae are united at their points, which cannot be 

 the case, since, according to the same author's description, the eighth row is absent ; it 

 is in reality the third and fourth and the fifth and seventh rows which unite at their 

 ends. Suffrian assumes ten rows in all the species of Cryptocephalidse ; and although 

 these are generally present, there are plenty of exceptions ; where there are less it would 

 be better, to avoid confusion, to count and describe them according to the number present.
