Distinguished from A. procerus, which is also an oblong species, 

 by its very much smaller size and broader and shorter thorax (the 

 thorax in ^. jsrocerws being for this genus remarkably long), and in 

 the ^ also by the shorter and less curved tibiae, and the narrower 

 groove of their under-surface. 



Anachalcos MAGNUS. — Quoad formam et colorem A. cupreo similis, sed 

 miclto major tlioraceque margine laterali obtuse rotundato nee angulato. Cre- 

 herrime punctulatus. $ , tibia posticce sicut in A. procei'o biJieocuoscB sed minus 

 elongatce, apice intus sat prolongatce et calcari brevi, sulco inferiori lato : 

 pygidium apice medio alte rejiexum (velut uncinatum) laminaque ventrali 

 polita, segmento 5« medio transverse callosum. Long., 30 mm., c? ? . 



Eiver Lujenda, East Central Africa (Mr. Last). 

 In most of its characters, intermediate between A. cupreus and 

 A. procerus, the latter of which was found in the same neighbourhood 

 by Mr. Last. In A. cupreus, the apex of the pygidium in the ^ 

 is broadly rounded, and the margin equally and only slightly reflexed. 

 This obtains both in East African and West African examples. 



Onthophagus LTjJENDiE. — 0. lanistfe (Castl.) affinis et similis; differt 

 (<J) capitis cornu mow a basi deflecto medioque subtus valide unidentato, 

 necnon thorace cornubus 7'ecurvis latioribus et brevioribus, antice profunde 

 bifoveato et dorso late Icevisulcato. Lcete viridis elytris pygidioque fulvis, 

 clypeo et pygidio fulvo-pilosis, thorace lateribus crebre punctatis. ? differt 

 ab 0. lanista, ? , tantum tJiorace usque ad lobum basalem canaliculato, medio 

 basi solum Imvi. Long., 13 — 15 mm. 



E. Lujenda (Mr. Last). A large series of examples offering no 

 variation. 



The species is almost exactly intermediate, in structure as well as 

 in locality, between O. lanista, of the Cape and Natal, and O. negus 

 (Eaffray) , of Abyssinia. In the latter, the large deep thoracic foveas 

 are within and behind the horns, in O. lujendce they lie at the base and 

 in front of each horn, and are smaller, rounder, and better defined. 



Onthophagus Plato. — Oblongus, latissimus, depressus, niger opacus ; 

 capite brevi semicirculari ruguloso-granulato ; thorace dense sed discrete 

 nitido-granulato, parum convexo antice medio leviter depresso, medio basi 

 triangulariter breviter producto, margine laterali ante angulum basalem 

 dentifero deinde si^iuato ; elytris sat acute punctulato-striatis interstitiis 

 planissimis, minute discrete pilifero-punctulatis pilis griseis recumbentibus : 

 subtus nigro-nitidus. — S , carina anterior subobsoleta, posterior in laminam 

 latum ohliquam elevata utrinque cornu valido compresso curvato apice sub- 

 uncinato ante medium intus uiiiramoso : thorace disco tuberculis duobus 

 altis acutis distantibus. Long., 31 mm.
