136 ON THE SCARITID.E OF NEW HOLLAND, 



base to within a third of a line of the anterior margin, and on 

 each side between the medial line and the lateral margins, and 

 near the anterior margin there is a slightly impressed punc- 

 ture. The elytra are marked with very fine punctured strise 

 to be seen only under a lens. They have also a few punctures 

 on the basal margin, and one near the apex. The fore tibiae 

 are bidentated externally. 



4. — Carenum gagatinum. 

 Nigrum nifcidum oblongum, capite utrinque canaliculato, tho- 

 race subquadrato angulis joosticis rotundatis, elytris ovatis 

 thorace angustioribus. 

 Long. 14 lin., lat. 4 lin. 



This species is black, glossy, and of an elongated form. The 

 head is large, thick, and emarginated in the middle of its an- 

 terior margin, with the facial canals taking their rise near the 

 posterior margin of the head behind the eyes, and extendmg for- 

 wards and inwards to near the clypeus, where they turn out- 

 wards nearly at right angles towards the anterior angles of the 

 head ; there are also two somewhat distant setigerous punctures 

 above each eye. The thorax is about as long as broad, truncated 

 in front, rounded at the posterior angles and truncated at the 

 base ; the medial line from the basal margin to within half a line 

 of the anterior is distinct. The elytra are long and slightly 

 narrower than the thorax ; they are perfectly smooth and free 

 fi'om markings, excepting a few punctures on the basal margin, 

 and a row of punctures close to each lateral margin. The fore 

 tibise have two strong acute teeth on their outer margin, the in- 

 termediate tibife have only a short one. The tarsi are piceous. 



Of this singular form there is but one example in the collec- 

 tion, and I should say that of all the species of Carenum known, 

 the G. quadrijpunctatum from Port Denison described in my 

 former paper on the Scaritidce is the one which has the greatest 

 aifinity to it, although the species do not much resemble one 

 another. 



5. — Carenum elongatum. 

 Nigrum nitidum oblongum, capite utrinque sulcato postice 

 trans versim canaliculato, thorace elongato nntice tmncato
