BRUCHUS. 491 
sponding sex of B. impiger. It has no very salient character, but is not apparently 
closely allied to any other species, and may be distinguished by the coarse punctuation 
of the thorax, and the porous-like punctures on the pygidium. 
116. Bruchus umbraculatus. 
Kytorhinus umbruculatus, Motsch. Bull. Mosc. 1873, ii. p. 207 *. 
Hab. Panama !. 
It is impossible to form any opinion as to this description, but as Motschoulsky’s 
other “ Kytorhini” belong perhaps to this section, and as he states the femora to be 
unarmed, I place it here. He records it as found in the seeds of a Convolvulus on 
the Isthmus of Panama, in March, and it may probably be a species of which I have 
not seen specimens. 
§ 8. Species not identified, their position quite uncertain. 
117. Bruchus oculatus. 
Bruchus oculatus, Say, North Am. Cure. p. 2*; Lec. Say’s Am. Ent. i. p. 260. 
Hab. Mexico }. 
118. Bruchus triangularis. 
Bruchus triangularis, Say, North Am. Cure. p. 1’; Lec. Say’s Am. Ent. i. p. 259. 
Hab. Mexico 1. 
It is not probable that these two species of Say’s will ever be identified; B. triangu- 
laris is, however, described as having the elytra marked in a manner I have not seen in 
any of the species we have received. 
119. Bruchus lapsane. 
Bruchus lapsane, Motsch. Bull. Mosc. 1878, ii. p. 235°. 
Hab. Panama “in sem. Lapsane” 4. 
In this species the femora are said to be unarmed, and the length # lin. 
120. Bruchus punctatostriatus. 
Bruchus punctatostriatus, Motsch. Bull. Mose. 1878, ti. p. 227’. 
Hab. Panama 1. 
121. Bruchus rufomaculatus. 
Bruchus rufomaculatus, Motsch. Bull. Mosc. 1873, ii. p. 222'. 
Hab. Panama 1.
