RECLASSIFICATION OF SUBFAMILY AGRYPNINAE 241 
SEXUAL DIMORPHISM. In the majority of species there are no obvious differences 
between the sexes. In a few species (e.g. aequalis (Candéze)) the antennae of the 
males are longer than those of the females. In some other species (e.g. babaulti 
(Fleutiaux)) the females are larger and have a stouter appearance than the males. 
DISTRIBUTION. The genus is represented in all parts of the world except South 
America. 
BIOLOGY AND HABITS. The early stages of the larva of L. fuscipes (Fabricius) 
have been described and figured by Fletcher (1919). The larvae of this species 
and of L. mastersi (Macleay) are predaceous and may be of some economic impor- 
tance. It seems probable that the larvae of fuscipes attack larvae of Oryctes 
rhinoceros Lesne in Mauritius and the larvae of mastersi are believed to play an 
important part in keeping down the numbers of Rutelid and Melolonthid larvae, 
which are serious pests of sugar-cane plantations in Australia (Illingworth, 1g2r : 16). 
THE SPECIES INCLUDED IN THE GENUS 
Arnett states that the genus is moderately large and that current catalogues 
list 80 species (Palaearctic, 9; Indomalaysian, 30; Australian and Oceanic, 7; Africa 
and Madagascar, 31; Americas, 3). It is not immediately clear how Arnett arrives 
at these figures. The most probable explanation appears to be that they are based 
on the Schenkling (1925) catalogue of Agrypnus without taking into account the 
species which appear more than once (e.g. aegualis Candéze occurs both in the 
Indomalaysian region and Australia) or the corrections and additions listed in the 
addenda and corrigenda at the end of the second volume. Schenkling lists the 
following number of species in each section: Palaearctic, 9; Indomalaysian, 28; 
Australian and Oceanic, 7; Africa and Madagascar, 28 and the Americas, 3. 
With the addition of two Indomalaysian species (lopezei Fleutiaux, 1934 and 
pescadoriensis Miwa, 1934) and three African species (accwminatus, confusus 
| and proximus Fleutiaux, 1935) described subsequently, these figures agree with 
| Arnett’s. 
| In the catalogue which follows, the species listed in the uncorrected Schenkling 
| catalogue together with the five above mentioned species are assumed to have 
_ been transferred to Lanelater by Arnett, 1952: 105. All others are recorded as 
new combinations. 
Lanelater is the only genus included in the Agrypninae in which scales are entirely 
absent. This characteristic together with the long antennal grooves and the 
presence of tibial spurs makes the generic attribution of specimens and in many 
cases of species known only from the description a relatively simple matter. It 
has therefore been considered unneccessary to record the data on the specimen 
or specimens on which the generic attribution is based.
