184 LONGICORNIA. 
corpus paullulum longioribus, nigris, articulis 3°-6™ basi cinereis ; corpore subtus et pedibus griseo-nigris, 
femoribus tibiisque annulis, tarsorum articulo primo cinereis. 
. Ovipositor sat elongatus, valvula dorsali marginata, supra obsolete sulcata, ventrali apice emarginata lobis 
subobtusis. 
Long. 63 lin. Q (excl. ovipos.). 
Hab. GuateMaLa, Totonicapam (Champion). 
7. Astynomus decorus. 
Precedentibus similis, sed differt elytris utrinque supra epipleuras obtuse carinatis. Elongato-oblongus, 
convexus, lateraliter compressus, grisescenti-niger, nigro punctatus; elytris setosis, supra Ineequalibus, 
asperato-punctatis, utrinque maculis angulatis quatuor nigro-velutinis ochraceo marginatis (prima haud 
procul a scutello, suturali, communi, 2* ante, 3* post medium, discoidalibus, quartaque transversa prope 
apicem), apice transversim truncatis, angulo exteriore paullo producto; capite angusto, vertice maculis 
duabus atro-velutinis; thorace tuberculo laterali mox pone medium valido, recte exstante, dorso convexo, 
ineequali, nigro quadrimaculato maculis ochraceo marginatis ; antennis (2 ) modice robustis, quam corpus 
fere dimidio longioribus, nigris, articulis 3°-6™ basi cinereis ; pedibus nigris, cinereo piperitis. 
Q. Ovipositor valde elongatus (nigro et cinereo-piperitus), lamina dorsali acuta, medio sulcata, ventrali 
profunde fissa. 
Long. 7 lin. @ (excel. ovipos.). 
Hab. Guatemara (Sallé). 
The lateral carina of the elytra taken alone would necessitate the location of this 
species in the genus Eutrypanus ; but all its other characters are those of Astynomus, 
and the length of the ovipositor and its cleft lower valve are unlike any thing known 
in Hutrypanus. In its form and markings it most resembles 4. melanophilus (Chev.) 
of Venezuela; but it is much darker in colours. I have adopted the MS. name given 
to it in the Sallé collection. 
OLENOSUS. 
Olenosus, Bates, Trans. Ent. Soc. 1872, p. 205. 
The male only was known when I drew up the characters of this genus ; since then, 
having seen the female, and found that it has an elongated ovipositor differing very 
little in relative length and shape from the same organ in Acanthocinus, it has become 
necessary to remove the genus from the neighbourhood of Oreodera, where it was 
originally placed, into that of Acanthocinus and Astynomus. It is amply distinguished 
from both genera by its strongly clavate antennal scape and the long and denticulated 
anterior tibie of the male. The sternums, both of the pro- and mesothorax, are much 
narrower between the coxe than in the allied genera, and approach in form the same 
parts in Leiopus and Lepturges.
