A total of 151 species from the subfamily Cerambycinae were evaluated. The number of genera and species evaluated in this study is shown in Table 1. Specimens available for this study came from various sources: Sarawak Museum Collection, Kuching (S. M. Coll.); Unimas Insect Reference Collection, Universiti Malaysia Sarawak (UNIMAS Coll.) and Sarawak Forestry Department, Kuching (For. Dept. Coll.).

Collecting was mainly done using the light sheet trap consisting of a piece of white cloth (1.5 m x 2 m) with a 160 W mercury vapour lamp powered by a 220 - 240 V portable generator. The trap was switched on from 1800 - 2400 hours. Specimens were picked off from the sheet using killing jar filled with ethyl acetate and were either pined in the field or kept inside the killing Jars for transportation. In the laboratory, all fresh specimens were kept in oven at 37º C for 14 days before being transfered into standard insect drawers.

Aerial catching were done along jungle or forest trails, open clearing such as newly logged secondary forest, log ponds and logging camps. Specimens collected were treated in the same manner as above.

All specimens were examined using a Jena Carl Zeiss stereomicroscope (0.8 X - 4.0 X) illuminated by a 6V halogen lamp with light-blue filter. Species identification were based on references as followed: Pascoe (1869); Gahan (1906); Aurivillius (1912); Gressitt & Rondon (1970); Gressitt (1951) and Duffy (1968).

Most colorphoto plates were taken using a AF Nikon camera (F-601), AF Micro-Nikkor 105 mm f/2.8 lens and Kodak Gold III film. Two 6V halogen lamps were used as additional light source beside daylight illumination. Plat 4f, 4g, 4h, 12a, 12b and 12e were taken using a AF Nikon camera (F-601) mounted to a Stemi 2000-C (Carl Zeiss Stereomicroscope).
