210 Descriptive Catalogue [1896. 



Gen. LACHANISSUS. 



The generic character are those of Metaxymorplius, the difference 

 between the two consisting in the absence of serration or pectination 

 of the claws ; the under part of the tarsi is also less setulose, and 

 there is no trace of punctures on the third interval. 



The facies of these insects is not unlike that of some Olisthojms, 

 but they are differentiated, not only by the shape of the ligula and 

 paraglossae, but also by the truncate elytra. 



Synopsis of Species. 



Pale testaceous ; elytra with an infuscate patch deceptor. 



Pale testaceous ; elytra without any infuscate marking . . . . inconspicuus. 



Lachanissus deceptor. 



Pale testaceous, with the prothorax yellowish red ; elytra very finely 

 punctato-striate, semi-transparent, and having on each side an 

 infuscate patch extending from the second to the sixth intervals, 

 ascending from the apex to above the median part on the fourth, 

 fifth, and sixth intervals, and only on the median part on the second 

 and third. Length 6 mm. ; width 2^ mm. 



Hah. Cape Colony (Worcester). 



Has the general appearance of Metaxymorphns namaqitensis ; the 

 prothorax is redder and less transparent ; the elytra are broader, and 

 the infuscate patch more apparent. 



Lachanissus inconspicuus. 



Pale testaceous, with the prothorax yellowish red ; elytra very 

 finely punctato-striate, semi-transparent, and without any infuscate 

 marking. Length 6 mm. ; width 2^ mm. 



Hab. Cape Colony (Oudtshoorn). 



Gen. CALLIDOMOEPHUS. 



Mentum, ligula, and paraglossa, antennae and palpi as in Jletaxy- 

 morphus ; mandibles not projecting so much, but head and prothorax 

 similar ; elytra parallel, plane, truncate behind ; joints of the anterior 

 tarsi cordiform, the fourth one incised, all of them bristly and very 

 densely squamulose underneath, intermediate and posterior ones 

 squamulose, but in less degree ; claws serrulate. 



The characters of the present genus, distinguishing it from its ally 

 Metaxymorphns, consists mostly in the more cordiform joints of 

 anterior and intermediate tarsi, which are also more squamulose 

 underneath, and in the male the anterior ones have a double series 

 of closely set squamae in '' chevron " ; the general facies is that of a 

 Callida, but the shape of the prothorax is that of Metaxymorphns.
