Long. 25 mm., elytr. 16, lat. 0. 



Head long, reminding one of Mecosaspis Thorns., with strong punctures and 

 irregular wriuliles on the anterior part of the front, finely and densely i)unctnred 

 between the eyes. Sides of the prothorax nearly impunctate, with a few wrinkles ; 

 a curved groove above and in front of the sharp lateral tooth entirely smooth 

 and shining ; disc somewhat gibbous at each side close to the anterior constriction, 

 transversely wrinkled, these wrinkles feeble and irregular in front, regular and 

 strong towards the base. -Prothorax above at each side, and elytra clothed with 

 a thin black ])nbescence ; snture with a yellowish grey pubescence. Tibiae and 

 tarsi covered with an ochraceous pile. 



Hah. Sierra Leone. 



Distinguished from the other species of lliis genus by its elongate head, and 

 its entirely rnfons antennae and legs. 



Callichroma Serv. (nee Latr.).* Type: Cenimhi/z suturalis Fa\>v. 



Antennae slender, longer than the body, at least in the mtlt; ; jirothorax 

 laterally toothed or not so ; seutellum slmrt : prosterual process regularly arched ; 

 four anterior femora clavate or subclavate, iiind femora slender, not sinuate at the 

 apex ; four anterior tibiae, or all tibiae carina! c ; sixth abdominal segment of thi- 

 male conspicuous, sometimes rather long. 



Some of the sjiecies hitherto referred to Callichroma, do not fit into the genns 

 — for example, 0. cuprewm Fahrs., ('. t/winzii White—and had better be separated. 

 Bates, Gahan, and other excellent specialists pointed out the following species, 

 standing in the Munich Catalogue under C'allic/iroma, as belonging to other genera : 

 calcaratum Chevr. is a P/iilematium, ckalijhe.aUmi White a Mecosaspis, carrori White 

 a Philematium, fahricii Schonh. an O.rijprosopm, (jon/i White is a true Callichroma, 

 and synonym with t'hilematium hottentottMm \^w\., laetim Hope is a Mecoa((spis, 

 neoxenum. White an Aphroilisiwm, speciosum Dalm. an (J.ri/prosop'is, and rire/is L. 

 (from Africa occ, not from Amer. mer.) a Fhilfm.afiiim. 



74. Callichroma afrum (L.). 



Sierra Leone, Gold Coast, and (Jameroons. 



One female specimen from the Gold Coast ditiers from the other examples I 

 have seen, in having the colour of the antennae and legs pale rufous, and tin- 

 wrinkling of the i)rothorax ipiite obsolete iu the middle. I projiose to name tliis 

 form Cali/chrama afrum ab. obsoletum. 



* Type of Latreille's genus Callichroma is Ciramlii/x (Armnin) iin'Sfhutius L.
