21. ASPIDOMORPHA TOGATA, ThomS. 



Aspidomorpha togata, Thorns. Arch. Ent. ii. 1858, p. 227. 

 One example. 



22. Aspidomorpha, sp. ? 



A single example. The disk of the elytra is wholly black. 



23. Aspidomorpha aruwimiensis, n. sp. 



Ovata,nigra; protliorace elytrisque pallide testaceis,hisirregularitei' 



(doi-so subseriatim) punctatis ; illo basi quam elytra angustiore, 



maculis duabus rotundis nigris, margine antico subrejlexo. 



Long. 12, lat. 9 millim. 



The body, head, legs, and antennae of this species are wholly 



black, the latter about as long as to reach to the hind angles of the 



thorax, their third joint half as long again as the fourth. The 



thorax has the extreme edge of the margin blackish ; there are a few 



obsolete punctures on each black spot and on the lobe just before 



the scutellum. The scutellum is black, but has a yellow mark at 



its apex, it is indistinctly impressed. The humerus is prominent ; 



the elytra are destitute of marks above or beneath, the extreme edge 



is very faintly brownish ; the punctuation is distinct but irregular, 



here and there, as near the suture and in one row starting from 



the callus, forming series. 



Two specimens of this insect were obtained by Mr. Bonny in the 

 Aruwimi Valley. It has not very much the appearance of an Aspido- 

 morpha ; the claws are, however, pectinate at their base ; and in 

 general structure it seems to me to agree better with that genus 

 than with any other known to me. 



24. Laccoptera intricata, Klug. 



Laccoptera intricata, Klug, Bohem. Monogr. iii. p. 59. 

 One example. This species is extremely common at Old Calabar 

 and at other places in Guinea. 



25. Cassida signatipennis, Bohem. 



Oassida signatipennis, Bohem. Monogr. ii. p. 345. 

 One specimen. This species is also common at Sierra Leone and 

 in Senegal. 



26. Cassida bonnyana, n. sp. 



Cassidse hepaticse statura et summa similitudine; nigra, prothorace 



elytrisque brunneis, his vix nitidis, creberrime minute punctatis, 



illo punctis duobus discoidalibus nigris, margine antico elevato. 



Long. 13, lat. 9 millim. 



The inner side of the first four joints of the antennae, the 



epistoma, and a dot on the crown of the head are rufous ; the thorax 



and elytra reddish brown, on each side of the middle of the disk of 



the former is a black dot of medium size, and this together with the 



rather dull surface will at once distinguish this species from 0. hepatica
