fourth and sixth interstices each with a very short mark at the base, the seventh with 
a short mark behind the middle; outer margin yellow from behind the shoulder to 
the middle. Under surface of the head and metarostrum not punctate, but with very 
strong asperities ; prosternum with but few asperities. | 
We have received one specimen only of this very fine species; it is allied to 
R. severini, but is larger, and has the thorax dull, the elytra with three impunctate 
strie next the suture, the prosternum much less asperate, the yellow marks a little 
different. In the structure of the male rostrum the insect approaches the genus 
Belophorus, but it lacks the peculiar form of the prothorax characteristic of the 
Antillean genus. The insect was probably found in Alta Vera Paz, though it is not 
labelled with any special locality.

Rhaphidorrhynchus severini, Senna, Ann. Soc. Ent. Belg. 1894, p. 602°. 
Hab. Muxico !, Juquila (6ge). 
We have received one specimen only of this species. Dr. Senna has kindly sent me 
his type, which is a small male, whereas our specimen is a large individual of that sex. 
It has the antenne longer, the tubercles of the prosternum very largely developed, 
and differs a little in the yellow markings, which have the appearance of being less 
constant in this species than they are in some others of the genus. There isa slight 
apical lateral dilatation of the rostrum of the same kind, though less distinct, as 
in &. principalis. 
8. Rhaphirhynchus variabilis. 
Rhaphidorrhynchus variabilis, Senna, Ann. Soc. Ent. Belg. 1894, p. 606°. 
Hab. Mexico, Oaxaca, Cordova (Sallé), Las Vigas (Hoge). 
We have received two individuals only, of the male sex, of this species.

2. Nigro-piceus, supra enescens, subopacus ; pedibus piceis, tibiis dilutioribus ; elytris versus suturam quadri-

Hab. Guatemata, Cerro Zunil (Champion). 
Two females from the above locality represent a species apparently very closely 
allied to R. variabilis, and having the same arrangement of striz and punctuation on 
the elytra, viz. three quite impunctate strie next the suture, then outside these 
another stria almost impunctate, and outside this series of fine punctures. ‘The yellow 
lines are, however, different from those of R. variabilis: the third interstice is yellow
