RHAPHIRHYNCHUS. 59 
15. Rhaphirhynchus linearis. 
Rhaphidorrhynchus linearis, Senna, Ann. Soc. Ent. Belg. 1894, p. 607 ‘ 
Hab. Mexico 1, Toxpam (Sallé); GuatTEMaza, Zapote (Champion); Nicaragua, Chon- 
tales (Belt). 
The male has the under surface of the head and metarostrum dull, and bearing 
numerous granular asperities, but no foveolar punctures ; the front of the prosternum 
is also granular. In the female these parts are shining and bear no asperities, but the 
metarostrum bears beneath six or seven foveolar punctures. 
Six specimens. 
The three individuals from Zapote are a variety of small size and very slender form. 
16. Rhaphirhynchus anomalus, sp. n. 
@. Nigro-sneus, subtus nitidus, capite thoraceque cupreis, hoc transversim fortissime rugoso; elytris fortiter 
seriatim punctatis, flavo-variegatis, ad suturam stria prima impunctata, stria secunda obsolete punctata. 
Long. 15 millim. 
Hab. Panama, Bugaba (Champion). 
We have received one example only of this extraordinary insect ; it is distinguished 
from all the other species of the family by having the upper surface of the thorax scored 
by deep grooves; these cease at the sides, leaving the flanks polished and shining like 
the under surface. In other respects this female seems to be a normal Rhaphi- 
rhynchus; it is probable, however, that the male may possess some character peculiar 
to it. The metarostrum is short, vaguely longitudinally impressed. The sculpture of 
the elytra is deep and coarse ; the stria next the suture shows no trace of punctures ; 
the second stria is very indistinctly punctured; the third and fourth strie, on the 
contrary, are punctured so as to be coarsely crenate; outside these there are rows 
of large punctures; the third interstice is yellow for nearly the whole length, with, 
however, an interruption on the middle; the fourth interstice has a short yellow mark 
on the middle, the seventh a short mark behind the middle, the eighth a short mark 
some distance behind the shoulder. There is a very short tooth at the outer apical 
angle of each elytron. 
In size and general appearance this female is similar to the corresponding sex of 
R. linearis. 
17. Rhaphirhynchus jansoni, sp. n. 
Q. Nigro-zneus, subtus politus ; thorace capiteque subopacis ; elytris fortiter sculpturatis, versus suturam 
quadrisulcatis, sulcis duobus internis parum punctatis, tertio modice, quarto fortiter punctato, externe 
fortiter et profunde seriatim punctatis et ante apicem subsulcatis, apice sinuatim truncato, angulo externo 
parum prominulo, longitudinaliter flavo-lineatis. 
Long. 174 millim. 
Hab. Nicaragua, Chontales (Janson).
