32 - LONGICORNIA. 
Hab. Guatemaa, Zapote (Champion). 
Almost identical in the peculiar markings of the elytra with 1. quadriguttatum 
(White), which is a Heterachthes in its unridged antennal joints, whilst the present 
species has well-developed carine. The short, oblique, deep-black streaks of the elytra 
are rather closer together than in J. 4-gut¢atum, the anterior being a little before and 
the posterior a little behind the middle; they touch neither the lateral margin nor the 
suture, from which latter they are widely distant; and the anterior streak (directed 
obliquely backwards from the margin towards the suture) is rather more slanting than 
the posterior streak, which is directed a little forward from the margin towards the 
suture; both are margined with very pale yellow, as in L. 4-guttatum; and the space 
between the pair on each elytron is also pale yellow. The antenne are very short for 
an Ibidion, if, as I suspect from the thickened third and fourth joints, the single 
specimen before me is a male.

The white “ note-of-exclamation” spots on the elytra are often quite absent.

Hab. Mexico!; GuareMata, near the city (Salvin, Champion). 
This species was included in my paper (Trans. Ent. Soc. 1872) among the Longicornia 
of Chontales. On re-examination I doubt whether any of Mr. Belt’s specimens can be 
justly referred to it, as, inter alia, they all far surpass the size (95 millims.) given by 
M. Thomson in his diagnosis of I. mexicanum. The determination of the Guatemalan 
specimens is also doubtful. 
9. Ibidion cribripenne. 
Modice elongatum, castaneo-rufum, politum, breviter setosum, capite et thorace tenuiter sericeis, hoc relative 
previ, disco depresso postice in tuberculum elevato ; elytris apice obtuse breviter truncatis, grosse punctatis, 
medio castaneo-fuscis, fasciis duabus (versus suturam angustatis) pallidis; antennis ( 2) filiformibus, 
haud carinatis; tibiis simplicibus.
