AND SPECIES OF GALERTTCINp. 
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. bicolor 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, nititla, subtus nigra, prothorace pedibusque anticis flavis, his 
plus minusve piceo tinctis; supra flava, antennis (basi exceptis) scu- 
telloque nigris ; thoraee transversim sulcato, sulco fere recto, medio 
magis fortiter excavato ; elytris tenuiter pimctatis. Long. 31 lin. 
Mas. Abdominis segmento anali trilobato, lobo intermedio profunde 
concavo; pygidii apice obtuso. 
Fem. Abdominis segmento anali apice concavo-emarginato, incissurae 
margine leviter deflexo. 
1 lab. Australia, Melbounie. 
Antennae moderately robust, filiform, the first joint, together 
with the basal portions of the second 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 paullo am- 
pliata, convexa, flava, nitida, antennis (basi exceptis), pectore abdomi- 
neque nigris, tibiis tarsisque nigro-piceis ; tliorace transversim sulcato, 
sulco medio fere obsoleto ; elytris infra basin leviter excavatis, 
tenuiter sed distincte punctatis. Long. 4 lin. 
Fem. Abdominis segmento anali rotundato, utrinque sinuato. 
Hab. New Caledonia. 
Eyes and antennae black, the latter with the two lower joints
