truncate; the exterior angles are obviously rounded, the interior scarce- 

 ly so. In figure and size this insect very much resembles Scolytus de- 

 structor: it will probably form a genus intermediate between Adelotopus 

 and Silphomorpha, a species of which is described below. For the ge- 

 nus the reader is referred to the paper by Mr. John O. Westwood, enti- 

 tled " Illustrations of the Relationships existing amongst Natural 

 Objects, usually termed Affinity and Analogy, selected from the class 

 of Insects," and published in the Transactions of the Linnean Society, 

 xviii. 409 : in this paper three new species of this remarkable order 

 are described. 



52. SilphomorpJia guttigera. Nitidus, glaber, ater, elytrorum macula 



mediana communi, longitudinaliter oblonga, laBte ferruginea. 

 (Corp. long. "3 unc. lat. '15 unc.) 

 Under bark of Eucalyptus. In size, shape and general appearance, 

 excepting the bright ferruginous spot, it closely resembles our com- 

 mon Gyrinus. This and the two preceding species run with great 

 agility, and are captured with difficulty : they never occurred in, or 

 particularly near, water. 



Natural Order. — Carabites. 



53. Cymindis aiistralis, Dej. Sp. Col. ii. 448. Under bark. 



54. Calleida vittata, Dej. Between the layers of Stringy bark and 



under Woolibut bark. 



55. Calleida suturata. Caput aspere punctum, cum antennis ferrugi- 



neum, oculis tantum nigris : prothorax obcordatus, latitudine 

 manifesto latior angulis posticis paullo productis, dorso longitu- 

 dinaliter profunde canaliculatus, medio fere glaber, marginibus 

 postico et lateralibus profunde punctis : elytra feiTugineo-iusca, 

 marginibus suturaque pallidioribus, 8-striata, striis sub lente 

 manifesto punctis, interspatiis quoque punctis ; elytronnn trun- 

 catura lata paullo concava, angulo externo rotundata, interno 

 subacuta. (Corp. long. '4 unc. lat. "13 unc.) 

 Under bark. 



56. Lehia corticalis, Dej. Sp. Col. v. 390. Between the layers of 



Stringy bark and under Woolibut bark. 



57. Lehia callida. Caput Iseve, ferrugineum, fere trigonum, antennis 



obscurioribus, oculis nigris : prothorax la^vis, feiTugineus, longi- 

 tudine latior, truncatura lata, recta, angulis quadratis, bene de- 

 terminatis, vix acutis : elytra 8-striata, striis subtilissime punctis, 

 interspatio marginali punctis nonnullis magnis interrupto, ceteris
