Family CORYLOPHIDiE. 
Catalogue of the Insecta oj the Oriental Region, No. 9. Order Coleoptera, 
Family Corylofiudji — By E. T. Atkinson, B. A. 
Matthews places this family close to the Silphidse, but would separate 
Aphanocephalus as a distinct family ( Pseudocorylophidce ) to be placed 
near the Cocotnellidte. Leconte observes that ‘ the wings fringed with 
long hairs give this family a certain affinity with the Trichopterygidse, 
while the loose antennal club, and the comparatively small size of the 
fourth joint from the end, in several genera, show an unmistakeable 
resemblance to Anisostoma, and other small Silphidse. The form of 
the mandibles and the structure of the tarsi, however, distinguish this 
family from all allies.' Jacquelin Duval, forms two groups : — Corylophini 
in which the head is entirely hidden beneath the anterior margin of the 
pronotum, broadly rounded and dilated iu front; more or less rounded 
before the eyes. Orthoperini in which the bead is more or less exposed 
in front of the anterior margin of the pronotum which is more or less emar- 
ginate ; abruptly contracted [before the eyes. In his description of the 
species of the family that occur in Central America (Biol. Centr. Amer., 
Col., ii (i), p. 12) Matthews forms several tribes that need not be noticed 
here.
