PIEZOCORYNUS.—ALLANDRUWS. 319 
8. Piezocorynus simplex, sp. n. (Tab. XI. fig. 3.) 
d. Similar to the preceding. Rostrum shorter. Antenne much thinner, segment 8 broader, 9 a little longer 
than 8, 10 hardly twice as broad as long. Pronotum with apical mesial streak as in the preceding species, 
disc visibly depressed on each side of the slightly raised mesial line, also more depressed before carina 
than in P. strigifer; carina very feebly concave in middle, lateral angle less rounded off than in 
P. strigifer. Alternate interspaces of elytron subcostate, first three interspaces nearly as in P. strigifer, 
fifth also dotted with luteous. First three abdominal segments flattened. 
Length 3 millim. 
Hab. Panama, Volcan de Chiriqui (Champion), 
One male.

Now I have seen more specimens of P. plagifer I come to the conclusion that it may 
possibly intergrade with P. dispar, Gyll., being perhaps only a colour-variety of that 
insect. 
Found in some numbers in Central America. 
XI. ALLANDRUS. 
Allandrus, Leconte, Proc. Amer. Philos. Soc. xv. p. 396 (1876) (type: b¢fasciatus) ; Jord. Noy. 
Zool. xi. p. 242 (1904). 
Very close to Enedreytes, Schoenh. (1839). 
Range: America. 
1. Allandrus angulatus, sp.n. (Tab. XI. fig. 4.) 
¢ @. Black, variegated with grey; antenna (except club), tibise, and tarsi more or less rufous. Rostrum flat, 
not carinate, densely rugate-punctate, about half as long again as apically broad. Lye elliptical. Pro- 
thorax rugate-punctate, with a luteous patch before scutellum; carina convex, angulate in middle, the 
point of the angle directed forwards. Scutellum luteous. Llytra broader than in A. difasciatus, Lec., 
from North America, the grey pubescence a little denser before and behind, forming indistinct and 
irregular transverse bands. 
Length 24 millim. 
Hab. Panama, Volcan de Chiriqui 2500-4000 feet (Champion). 
A small series.
