Includes references.

Some biological aspects of the scelionid parasitoid species Trissolcus basalis Wollaston were described. Egg incubation period. durations of larval instars, prepupal and pupal periods were estimated. All stages and adult emergence were described. The egg bears a filament airoscopic plate and measured 100 and 50 µ in length and width, respectively. The egg incubation period ranged between 1- 2 days. L1 and L2 occupy structures keeping them floating on the yolk inside the host egg, which lacks in L3. Mean duration of the three larval instars were 1.2, 2.2, and 5.4 days, respectively. They measured 100, 350, and 600/1 in length and 50, 150, and 200/1 in width, respectively. The prepupal and pupal stage lasted 1-2 and 5-6 days, respectively. Adult emergence and differentiation between both sexes were described.
