ONCOMETOPIA. 233 
It is possible that this may be one of the many forms of Q. wndata, and I at first 
referred it to that species, but, as will be seen from the figure, it appears to be quite 
distinct. 
13. Oncometopia rubescens, sp. n. (Tab. XIV. fig. 24.) 
Oblonga, parallela; capite, pronoto, scutello et femoribus late rufescentibus, plerumque immaculatis ; capite 
modice producto, obtuso, rotundato, oculis magnis prominentibus; pronoto longitudine multo latiori, 
leviter sculpturato; scutello magno, fere levi ad medium asperato; tegminibus fusco-rufis, fortius 
punctatis, apicibus levibus late hyalinis ; corpore subtus violaceo, lateribus et apice abdominis albidis vel 
testaceis ; pedibus, femoribus rufis exceptis, testaceis. 
Oblong, parallel, with the front parts clear red, usually without spot or marking; metopidium rough in the 
middle, very finely wrinkled transversely at the sides; head moderately produced, vertex rounded ; 
pronotum strongly transverse, finely rugose; scutellum large, smooth at the sides, roughened finely in the 
middle; tegmina fuscous-reddish, with strong raised veins, plainly and rather strongly, but not very 
closely, punctured, the apex broadly, abruptly, and clearly hyaline; femora bright red, the tibie and 
tarsi testaceous ; underside purplish, the sides of the breast whitish; sides and apex of the abdomen 
testaceous. 
Long. 12-18 millim.; lat. ad hum. 3 millim. 
Hab. Guatemata, Cerro Zunil 4000 to 5000 feet (Champion); Panama, Bugaba, 
David, Volcan de Chiriqui (Champion). 
The type-form has the front parts bright red, without any markings; at most, there 
is a narrow longitudinal black line on the vertex, and an obscure dark marking or two 
on the metopidium and scutellum. The colour varies in distinctness, and in one or 
two specimens has faded to testaceous; this is probably the case with many of the 
species. O. rubescens may be an extreme form of O. undata, but there seems enough 
difference to keep it at present as a distinct species. 
An example from David is figured.
