Measurements and indices The total body length (in mm) is measured from the tip of mandibles to the apex of elytra as an unidimensional measurement, the convexity of body being not taken into consideration. Size range was determined by selecting the largest and the smallest specimens in the material investigated. The relative lengths of the last antennái segments (VI to XI on males, VII to XI on females) are given as values measured directly by the ocular micrometer. Interocular index (IOI) = interocular distance x!00/eye diameter. Interocular distance is the smallest distance between the inner edge of eyes. Eye diameter is the broadest distance between the inner and the outer edges of an eye in dorsal view (owing to the curvature of the eye, this is, of course, smaller than the actual diameter). IOI > 100 indicates that the interocular distance is broader, IOI < 100 narrower than eye diameter. Interantennal index (IAI) = length of antennái segment IX 100/interantennal distance. Interantennal distance is the distance between the inner edge of the abdominal sockets. IAI >• 100 indicates that the segment I is longer than the interantennal distance and inversely so with IAI < 100. Pronotal index (PNI) = pronotal length xlOO/pronotal width. Pronotal length is measured along the median line of the pronotum. Pronotal width is measured at the broadest point of the pronotum, whether it is at the base or anterior to it. PNI >• 100 indicates a lengthened pronotum, while PNI < 100 a transverse pronotum. The measurements were taken from a medium-sized specimen, except for the total body length. The individual variation of the above indices was not examined so these values are only informatory in nature. Nevertheless, they seem rather useful in separating and characterizing both genera and species. CHECKLIST OF THE AUSTRALIAN SPECIES OF LAGRIINA I.

Elytra fulvous, the rest of body bluish black. Antennae of males thick, segments VII and IX strongly expanded at inner side; segments VIII and X simple; segment XI bent, longer than 6 preceding segments combined (Fig. 1) Acerogria BORCHMANN, 1936 2 (1) Pronotum distinctly punctate, surface more or less evenly convex. Femora and tibiae not flattened. Colour pattern not as above. Antennae of males with segments simple or deformed in different ways, but never as above; segment XI nearly straight, never longer than 5 preceding segments combined, usually much shorter. 3 (8) Antennae of males with segments simple, as those of females.
