■elytra. The pubescence is silvery, short, and sparse, but my 

 example is certainly more or less abraded. 



ISTear Port Lincoln. Obtained by sweeping low plants. 



CYREMA, gen. nov. [Cryptogono affinis]. 

 Caput prothoraci mediocriter insertum; antennarum basis aperta ; 

 oculi magni, minus subtiliter granulati, intus subparalleli ; 

 epipleurse minus lat?e, subverticales, postice gradatim angus- 

 tat£e, contra pedes intermedios et posticos sat profunde 

 foveatse; prosternum inmedio longitudinaliter depressum, 

 utrinque ad pedum receptionem excavatum ; mesosternum 

 transversum sat magnum, antice truncatum ; abdomen seg- 

 mentis 5 (basali et apicali longitudine inter se subaequalibus) 

 conformatum ; suturse ventrales bene impresses ; sterna 

 utrinque ad pedum intermediorum et posticorum receptionem 

 excavata ; lamellse (abdominales segmenti basalis apicem 

 attingentes, cum margine apicali postice confusee) valde con- 

 spicuae, concavae ; femora fortiter compressa ; tibi^ minus 

 validse, anticis fortiter arcuatis. 



The antennae are very short, but I have completely failed to 

 arrive at any certainty as to the details of their structure, so it 

 is better to say nothing about them.* There is very little 

 pubescence on my two specimens ; probably, however, they both 

 are more or less abraded. The genus would seem to be allied to 

 several already described, but very distinct from all. The concave 

 lamella of the under surface Avith their margins very strongly in 

 relief, in the concavities of which the legs are contractile, together 

 with the foveated elytral epipleurai and the great development of 

 the abdominal lamellae, are suggestive of Cryptogonus^ but on the 

 -other hand the mesosternum is well developed, and the ventral 

 segments are only five in number. The form of the presternum, 

 with a flattened longitudinal median space strongly narrowed 

 from base to front, in combination with the characters men- 

 tioned above, will distinguish this genus from all others known 

 to me. The claAvs are feebly appendiculate, and rather large.

* The antennae of some Coccitiellidcc are very difficult to examine ; owing to 

 their minuteness and their concealed position it is often impossible even to break 

 them off from a dry specimen successfully for microscopic study. Dr. Chapuis 

 (Gen. Col. xii., p. 239) speaks of having uselessly sacrificed his unique example 

 ■of Cryptogonjis in the hope of furnishing information concerning the antennae 

 -which the author of the genus had been unable to supply. I have to deplore a 

 -similar result of my study as regards one of my two specimens of Cyrema, and 

 my unique exponent of Lipernes is none the better lor my explorations in the 

 ^•egion of its antennae.
