HEBASCUS. 
Hebascus, Erichson, in Germar’s Zeitschr. iv. p. 311 (1848). 
This is a genus comprehending at present only about half a dozen species confined to 
Central and South America, Although placed in a different subfamily to the European 
and North-American genus Cychramwus, yet it comes very close thereto; but I think the 
two may be kept distinct, as Hebascus has a serial arrangement of the pubescence and 
the mesosternum in front more strongly carinate. H. aurantiacus, one of our species, 
makes a nearer approach to Cychramus than some of the other representatives. Indeed, 
owing to the distinctions in the form of the prosternal process, our Hebasci are divisible 
into sections which are almost, if not quite, as distinct from one another as Hebascus 
is from Cychramus. 
Hebascus, especially in the second section, appears at first sight to belong to the series — 
of genera of Strongylinz in which the prosternal process is open behind; but it really 
belongs to the Pocadius group of genera in which there is a posterior perpendicular 
face to the process; this face is, however, only short, and in the second section is 
concealed by the horizontal (lower) surface being prolonged backwards beyond it. 
§ 1. Lower face of the prosternal process but little produced beyond the 
vertical face. 
This section comes very near to Cychramus. 
1. Hebascus mexicanus, sp. n. 
Circularis, convexus, testaceus, antennarum clava nigra; elytris quasi costatis, setulis seriatis numerosis, decli- 
natis, interstitiis parce pubescentibus. 
Long. 33 millim. 
Hab. Mexico, Cordova (Sallé). 
Antenne with the club broad, short, and black. Thorax rather coarsely punctured, 
strongly setose, the base almost straight. Elytra with very regular series of closely-placed 
sete, which are short, curvate, and much directed backwards, so that they almost give 
rise to the appearance of very fine coste; there is no trace of striation, but between 
the series of sete are two rows of shallow, not large punctures, each bearing a very 
short hair. Prosternal process quite short; middle of the breast smooth and shining. 
Four specimens. 
2. Hebascus bugabensis, sp.n. (Tab. XI. fig. 9.) 
Circularis, convexus, testaceus, antennarum clava nigra; elytris quasi costatis, setulis seriatis numerosis, de- 
clinatis, interstitiis parce pubescentibus. 
Long. 3 millim. 
Hab, Panama, Bugaba (Champion).
