A NEW SPECIES OF CRABRONID^E FROM BORNEO. 283 



The following seem also to have been omitted by Mr. Distant, 

 and there are many more records since the publication of his first 

 volume : — 



Aspongopus janus on Cucurbita and Cucumeris. 



Canthecona cognata preys on a croton-ravaging caterpillar. 



Brachy platys silphoides is said by Westermann (1821, Mag. 

 Ent. iv. 411-27) to be very injurious to Oryza sativa in India, 

 but I have no access to the work. It is translated in Eev. 

 Ent. i. 111-1833. 



Myodocha acutus (= Leptocorisa, Dist.). This is a notorious 

 rice pest; also found on "rubber." It is preyed on by Cicindela 

 sexpunctata. 



Leptocoris augur (= Serinetha, Dist.). Supposed to be 

 mimicked by the lepidopteron Phauda jiammans (cf. Eothney, 

 1894, Proc. E. S. London, p. xv.). It occurs on Gossypium 

 herbaceum and Schleichera trijunga. 



Antilochus coquebertii preys on Dysdercus cingulatus (Kirkaldy, 

 1900, Entom. xxxiii. 295). 



Fontejanus icasmanni is termitophilus. (Breddin, 1903, Soc. 

 Ent. xvii'i. 75.) 

 |/ Zamila aberrans is destructive to Saccharum ojfjicinarum. It 

 has been partly confused by Distant with Dictyophora pallida. 



^ Peregrinus maidis ( = Pundaluoya simplicia and v Libumia 

 psylloides, Dist.) is destructive to Zea mats.
