IX.—WHitherto undescribed Platypodidee and Secolytide from 
Portuguese Kast Africa. By Lt.-Col. W1NN SAMPSON, 
F.E.S. 
A NUMBER of specimens from Portuguese Hast Africa, 
collected by Mr. C. B. Hardenberg, having been handed to 
me by the Director of the Imperial Bureau of Entomology 
for determination, the following appear to be new species :— 
Crossotursus hardenbergi, sp. 0. 
3. Head and prothorax dark brown ; elytra dirty yellow, 
darker towards the apex. front flat, shagreened surface 
lightly punctured on the upper half and more deeply on the 
lower, with a slight median longitudinal depression and 
obscure strize below the eyes, the latter being sharply de- 
pressed on their inner sides; the whole surface sparsely hairy 
and with a row of yellow hair above the mouth; the vertex 
has a clearly defined edge with a strong central carina, the 
surface on each side being dull and granulate, becoming 
polished and somewhat swollen, with irregularly placed and 
various-sized umbilical punctures towards and above the eyes. 
Prothorax oblong, anteriorly dull, the rest of the surface 
polished, with scattered umbilical markings and small punc- 
tures, especially towards the posterior edge and on each side 
of the central longitudinal groove, which extends from close 
to the base for one-fourth the length of the prothorax, pre- 
ceded by a faintly marked ridge reaching nearly to the anterior 
margin. lytra (fig. a) the same breadth as and one-half 
longer than the thorax, striate-punctate, the first stria rather 
deeply and closely punctured; the interstices faintly uniseriate- 
punctate, the third not broadened basally ; the first, second, 
and third coalesce apically, forming an oblique truncate edge, 
the outer acute angle extending beyond the remaining inter- 
stices, the fourth narrowed and terminating before reaching 
the apex ; the fifth is obliquely truncate, broadened apically, 
and nearly the same length as the sutural angle; the sixth is 
slightly shorter, narrowed, and apically obtuse ; the seventh 
transversely truncate and equal in length to the sixth; the 
eighth shorter than the seventh and obtusely rounded; theninth 
is the same length as the seventh and twice as broad as the 
eighth, and obliquely truncate, the outer angle being very acute. 
Abdomen (fig. 6) with the first and second visible segments 
centrally depressed, the excavation in the second having the 
sides slightly divergent as far as the inner posterior angles, 
and then rounded and fringed with hair, becoming incurved
