134 HETEROMERA. 
female, narrower in the male, punctured like the head, the angles prominent, the base with an oblique 
shallow impression on each side about the middle ; elytra closely and rather coarsely punctate-striate, the 
strie deeply impressed, the interstices closely and irregularly wrinkled (transversely) and punctured ; 
outer apical angle of the anterior tibiee produced into a strong blunt tooth; intermediate and posterior 
tibiee coarsely roughened and setose. 
Length 6-7 millim. (¢ 9.) 
Hab. Mexico, Ventanas, Presidio (Forrer), Cordova (Sal/é), Tehuacan, Jalapa (Hége), 
Yucatan (coll. F. Bates); Guatemata, San Gerénimo (Champion); Panama, San Feliz, 
Bugaba (Champion), Obispo (Salvin). : 
Allied to U. obliquus, Horn, from Cape San Lucas, the thorax formed as in that 
species, and differing as follows:—The upper surface closely but less regularly clothed 
with rather coarser and browner pubescence, the sides of the thorax less thickly 
pubescent, the striz more deeply impressed, and the punctures coarser. In the male 
the thorax is narrower and less transverse than in the female; fresh examples are 
densely clothed with brownish or golden, short, recumbent hairs. 
In some examples the interstices of the elytra are distinctly wrinkled transversely, 
and more closely punctured than in others. 
2. Ulus lineatulus. (Tab. VI. fig. 14.) 
Broad ovate, convex, brownish black, sparingly clothed with rather fine cinereous pubescence. Head rather 
closely and coarsely punctured ; prothorax widest at and narrowing from the base forwards, scarcely 
rounded at the sides, not very convex, closely and rather coarsely but not confluently punctured, the 
punctuation a little finer and more scattered than upon the head ; elytra narrowing from about the middle, 
somewhat pointed behind, closely punctate-striate, the: interstices very closely, finely, and irregularly 
punctured and wrinkled, the pubescence on the alternate interstices lighter in colour towards the sides ; 
anterior tibiz gradually widening to the apex, the outer edge scarcely emarginate before the apex ; inter- 
mediate and posterior tibiee coarsely roughened and setose. 
Length 63-7 millim. (¢ @.) 
Hab. Guatemata, Champerico, Las Mercedes (Champion). 
Common on the sea-coast at Champerico and also found inland. JU. lineatulus may 
be known from U. obliquus and U. hirsutus by the more distant and finer punctuation 
of the less convex but similarly formed thorax, the elytra more pointed behind, the 
upper surface more finely and sparingly pubescent. 
The following genus is of uncertain position :— 
PENICHRUS. 
Penichrus, De}. Cat. 3rd edit. p. 231. 
Mentum small, narrow, trapeziform, inflexed on each side anteriorly, the anterior angles indistinct; last joint. 
of the maxillary palpi triangular ; antenne very stout from the base, long, passing the base of the pro- 
thorax, third joint short and not equalling the united first and second, the joints from the third decreasing 
in length and widening outwardly, eighth to tenth broad and transverse, eleventh very large, and almost 
equalling the united ninth and tenth, finely and sparingly setose (in our species), or with shorter and 
coarser projecting sete (P. nanus, Dej.); head long (the front especially), broad in front and scarcely 
narrowing anteriorly, not deeply sunk into the prothorax; the epistoma broadly but feebly emarginate,
