64 Mr. Gilbert J. Arrow's Cunlribution to the 



The antennae are niiich shorter than usual in the Endo- 

 mychidae, with the three-jointed club not much dilated, 

 but the last joint strongly asynnnetrical and pointed. 

 The hind legs are stouter than the rest and all the tarsi 

 are rather long, but the second joint is strongly lobed. 

 The general appearance rather suggests that of Litho- 

 philiis, although the anteiniae are longer, the tarsi more 

 lobed and the penultimate (third) joint more conspicuous. 

 The pronotum has very broad raised margins, as in 

 Stenotarsus. 



Mimolithophilus brevicornis, sp. n. 



Fusco-brunneus, anteimis, pedibus, pronoti et elytrorum later!- 

 busque rufescentibus, ubique dense punctulatus et sericeus; 

 oblongus, depressus, capite sat longe fulvo-pubescenti ; pronoto 

 dimidio latiori quam longioiij niaigiiiibus foititer elevatis, lateribus 

 antice arcuatis, postice contiactis, angulis anticis pioniinentibus, 

 baud acutis, posticis obtusis ; elytris longis, fere parallelis ; antennis 

 longitudine fere ad pronotum aequalibus.

This is the largest of the three species known to me. It 

 is more elongate and parallel-sided than the other two, 

 with the discoidal part of the pronotum smoother and the 

 sides less contracted beliind. The antennae are extremely 

 short in relation to the size of the insect. 



Several specimens were taken by Dr. Marshall. 



Mimolithophilus capensis, sp. n. 



Obscure rufus, dorsi medio obscuriori, corpore ubique coriaceo 

 et dense subtiliter sericeo; oblongus, baud convexus, capite fulvo- 

 pubescenti, pronoto antice dilatato, postice valde contracto, lateribus 

 medio obtuse angulatis, angulis anticis prominentibus, baud acutis, 

 posticis obtusis, marginibus lateralibus valde elevatis, disco intra 

 margines excavato; elytris sat longis, lateraliter leviter arcuatis, 

 humeris prominentibus ; antennis quam pronoto paulo longioribus.
