AND SPECIES OF aALERUCTNiE. 



177 



deep transverse groove. Elytra narrowly oblong, slightly dilated 

 posteriorly ; convex, very faintly excavated on the suture below 

 the basilar space, opaque, very minutely punctured. 



A. analis, Weber, agrees very closely in general form with 

 A. hicolor of the same author ; the structural differences, how- 

 ever, in the anal segments of the abdomen in both sexes, although 

 slight, are apparently constant, and sufficient to separate the two 

 insects ; A. analis is also smaller than the other species. 



2. AuLACOPHORA WiLSONi. Anguste oblonga, postice ampliata, 

 convexa, nitida, subtus nigra, prothorace pedibusque anticis flavis, his 

 plus minusve piceo tinctis; supra flava, antennis (basi exceptis) scu- 

 telloque nigris ; thorace transversim sulcato, sulco fere recto, medio 

 magis fortiter excavate ; elytris tenuiter punctatis. Long. 3^ lin. 



Mas. Abdominis segmento anali trilobato, lobo interraedio profunde 



concave ; pygidii apice ebtuso. 

 Fern. Abdominis segmento anali apice concavo-emarginato, incissurte 



margine leviter deflexo. 



Hah. Australia, Melbourne. 



Antennae moderately robust, filiform, the first joint, together 

 with the basal portions of the secoud and third, fulvous ; labrum 

 nigro-piceous ; eyes black. Thorax with its sides nearly straight 

 and only very slightly diverging from the base to beyond the 

 middle, thence obliquely converging towards the apex ; disk 

 transversely sulcate, the sulcation straight, rather more deeply 

 excavated in the middle. Elytra oblong,, dilated posteriorly, 

 convex, obsoletely depressed below the basilar space, the latter 

 sometimes obsoletely thickened ; the surface minutely punc- 

 tured. 



In addition to other structural differences, the sculpturing of 

 the thorax will distinguish the above insect from A. nigroscutata, 

 which species it closely resembles in coloration. 



3. AuLACOPHORA Perroudi. Elongato-oblonga, postice paulle am- 

 pliata, convexa, flava, nitida, antennis (basi exceptis), pectore abdorai- 

 neque nigris, tibiis tarsisque nigre-piceis ; thorace transversim sulcate, 

 sulco medio fere obsolete ; elytris infra basin leviter excavatis, 

 tenuiter sed distincte punctatis. Long. 4 lin. 



Fern. Abdominis segmento anali rotundato, utiinque sinuate. 

 Hah. New Caledonia. 



Eyes and antenna? black, the latter with the two lower joints
