170 Mr. M. Jacoby's contributions to the Icnowledge of 
latter. The species resembles somewliat C. callias, Sufif., 
but is much larger and more elongate. G. trigeminus, 
Chap., also differs in several particulars, and has spots 
instead of bands. 
Gryptocephalus quinquejplagiatusj sp. n. 
Broad and robust, black, above testaceous, the head with one, 
the thorax with two, black spots, finely punctured; elytra irregularly 
punctate-striate, the interstices finely punctured, with five black 
spots (3, 2). Length, 3^ lines. 
Head opaque, finely and sparingly punctured, flavous, with a 
transverse black band at the vertex, widened at the middle and 
having a trilobe spot attached to its lower margin ; a small black 
spot is also placed at the root of the antennae, these not extending 
beyond the base of the thorax, black, the lower five joints fulvous ; 
thorax nearly three times broader than long, the sides slightly 
rounded, the posterior angles moderately produced, the surface 
very finely and rather closely punctured, flavous, with a broad but 
short elongate stripe at each side not extending to the anterior 
margin; scutellum black, not longer than broad, the base with a 
fovea, the apex truncate ; elytra pale flavous, with irregular rows 
of strong punctures which become still more irregular at the sides, 
the interstices likewise irregularly but finely punctured, the suture 
narrowly black ; of the round small spots one is placed on the 
shoulders, two transversely before and two others below the 
middle, the outer two being more closely approached to each other; 
the legs, the last abdominal segment, and the pygidium flavous, 
the rest of the underside black, closely pubescent, the posterior 
margin of the prosternum bidentate, 
Mashunaland. 
In its system of coloration this species is allied to 0. 
jpardalis, Suff., and others, but diflFers quite from these 
and other African species of large size by the irregular 
rows of the elytral punctures and their finely-punctured 
interstices, which make the rows appear still more confused. 
It is very closely allied to C. hatesi (p. 174), and I am 
not certain whether it may not be merely a form of that 
species ; the spots of the thorax are, however, differently 
shaped and wider apart, the elytral spots are discon- 
nected, and the posterior ones are placed higher than in 
G. hatesiy and the inner one does not extend across the 
suture as in that species ; lastly, the elytra are not opaque, 
but shining.
