MACROSTOLA. 
Macrostola, Murray, Trans. Linn. Soc. xxiv. p. 331 (1864). 
Macrostola has hitherto included only three species, one found throughout our 
region, the others in South America; I now add a fourth from the State of Panama. 
The genus is very distinct and its position doubtful. There is no trace of any 
antennary grooves. 
1. Macrostola straminea. 
Macrostola straminea, Murray, Trans. Linn. Soc. xxiv. p. 382, t. 35. f. 7°. 
Hab. Mexico, Cordova (Sallé1), Teapa (Sallé, Hoge), Jalapa, San Juan Bautista 
in Tabasco (Hége); GuatemaLa, Zapote, Cahabon, Teleman (Champion); Nicaragua, 
Chontales (Janson); Panama, Bugaba (Champion). 
This insect, according to Mr. Champion, is found in the viscous pollen in the 
spathes of various Aroidee, usually in company with various Cyclocephale; it is a 
common species in our region, and it varies a good deal in size. 
2. Macrostola picea, sp.n. (Tab. IX. fig. 6.) 
Picea, depressa, nitida, oculis sat magnis; elytris regulariter seriatim punctatis, interstitiis lineis impressis 
longitudinalibus plus minusve abbreviatis et interruptis. 
Long. 43 millim. 
Hab. Nicaracua, Chontales (Janson) ; Panama, Bugaba (Champion). 
Head and thorax finely and sparingly punctate, the latter nearly straight at the 
sides but becoming slightly broader at the base. Scutellum impunctate. Hind body 
with three segments exposed and rather coarsely punctate. Female with the last 
dorsal plate somewhat prolonged, rounded and ciliate at the extremity; male with 
the last dorsal plate rather deeply emarginate in the middle at the extremity, the 
emargination filled by a supplementary segment much ciliate behind. Twelve 
examples; one only of them from Nicaragua. 
Closely allied to I. straminea, but readily distinguished by the dark colour and the 
smaller eyes; the hind body is more coarsely punctate and more densely ciliate at the 
apex. The largest individuals are scarcely so large as the smallest examples of 
M. straminea. 
CARPOPHILUS. 
Carpophilus, Stephens, Il. Brit. Ent. i. p. 50 (1830). 
This genus includes rather more than 100 described species, and is generally 
distributed throughout the world. A few species are nearly cosmopolitan, being 
distributed with groceries—dried fruits, sugar, &c.; but the great majority of the
