4. Ocnera hispida Forsk. Examinations of 136 adult beetles of Ocnera hispida Forsk . (Coleoptera: Tenebrionidae ) showed that only 22 specimens were infested with nematodes (16.17 %). Beetles were collected at Kerdasa (a village about 10 km from Cairo) and at Mosttord farm (near Cairo) on various dates during a period extending from September, 1966 to November, 1967. A number of 215 parasites were extracted from the 22 infested beetles (an average of 9.8 nematodes per beetle). Nematodes were found crowded underneath the elytra. Internal examination showed no infestation with nematodes. External infestation occured in both male and female beetles. Isolation and rearing experiments on several artificial media proved that the meat extract medium was the most suitable for nematode growth. Microscopic examination and measurements of both nematode male and female adults proved that the represented nematode species is Caenorhabditis dolic hura (Schneider, 1866) Dougherty, 1955. The following is the morphological description of the nematode. 4-1. Caenorhabditis dolichura (Schneider, 1866) Dougherty, 1955 (Pig. 5 ) Females (n = 10): L = 0.924-0.980 mm; a = 15.6-22; b = 5-7-6.0; c = 12.3-13-, V = 50.8-71 %. Males (n - 10): L = 0.924-0.957 mmj a = 20-24.3; b = 6.04-6.2; c = 20-24.2. The nematode species is characterized by a head with six offset lips,each lip with a fine papillae. Stoma (Figs. 5D and F) about five times as long as wide, metarhabdions each with a pair of large apparently hollow teeth. Esophageal collar surrounding about half stoma. Esophagus without a median bulb. 180
