80 RHYNCHOPHORA. 
head and thorax, in the female a little longer ; eyes small, moderately widely separated ; 
antenne inserted behind the middle, nearly as far from the eyes as the width of the 
head and eyes. Thorax small, short, much narrowed in front, sparingly and obsoletely 
punctured, without channel. Elytra a good deal narrowed towards the base, deeply 
but rather narrowly sulcate, the interstices moderately broad, convex. Legs slender ; 
tibize with a very slight infuscation in the middle ; intermediate coxe nearly contiguous. 
Three examples. 
74. Apion laterale, sp. n. 
Robustum, nigrum, supra e«nescens, setosum, corpore ad latera albido-vestitum, antennis pedibusque pallide 
flavis ; prothorace lato, dense punctato. 
Long. 23 millim. 
Hab. Mexico, Ventanas in Durango (fége); GUATEMALA, near the city (Champion). 
Rostrum short, in the male about as long as the thorax, in the female a little longer, 
rather stout, slightly attenuate towards the tip, feebly punctate, dull, finely setose ; eyes 
somewhat large, but little convex, separated by a moderately wide space; antenne 
yellow, short, inserted as far in front of the eyes as the width of the ocular interval. 
Thorax broad and short, greatly narrowed in front, densely but rather indistinctly 
punctate, finely setose, with a channel at the base in the middle. Elytra finely sulcate, 
rather closely pubescent. Under surface densely clothed with white setosity at the 
sides. Legs short, pale yellow; coxe and trochanters black ; middle coxe somewhat 
widely separated. 
75. Apion longicolle, sp. n. 
Angustum, nigerrimum, nitidum, antennis tibiisque testaceis vel fusco-testaceis ; rostro brevi, crasso ; prothorace 
elongato, cylindrico ; elytris striatis, singulo ad basin albido-cristato, ante apicem impresso. 
Long. 13-23 millim. 
Hab. GUatEMALA, Paso Antonio (Champion). 
Rostrum not curved, shorter than the thorax, thick, feebly setose; eyes rather large, 
convex, somewhat widely separated, the space between them strigose ; antenne inserted 
just behind the middle. ‘Thorax elongate and slender, the sides rather irregular in 
outline, owing to a very feeble transverse depression in front of the middle and a still 
more obscure one behind it; impunctate, bearing a very few, small, white hairs. Elytra 
narrow, finely striate ; each at the base with a small patch formed by some white hairs, 
and just before the extremity with a depression in which there are some white hairs. 
Femora nearly or quite black ; tibize either sordid yellow or strongly infuscate ; middle 
cox separated by a slender lamina. 
This insect is allied to A. constricticolle, and its location in another section, owing 
to the colour of the legs, is unsatisfactory, especially as this character appears to be 
variable ; as species the two insects are, however, quite distinct. 
Five specimens.
