(Thes. Ent.). Of this great group only 23 species were collected by 
Mr. Gates, including Ceroplesis hoiteniotia, C. cnwjitata, and two 
other species, Fhrissoma gi'gatitenin, CaUichroma latipcs, Haniati- 
cliei'iis scriceiis and deniicornis, and Auiphidesmiis aiialis, Olivier. 
Family Chrysomelid^. 
The Phytophagous or plant-eating beetles {Chrysoniela, Linn.), as 
may be inferred from their habits, are exceedingly numerous, both in 
species and individuals, in all parts of the world, more than 10,200 
species having been described. Some few groups are especially 
African, such as Pacilomorpha, Hope, belonging to the Megalopides, 
numerous species of Sagra, Antipa, Melitonoma, Acolastus, Eiiryins, 
Pausiris, Pallctia, Cyno, Macrocoma, etc. Only twenty-three species 
of these insects were taken by Mr. Oates, including Sagra /estiva, 
Gerst., DiampJiidia fevioralis, Gerst., Clythra tettensis, and various 
species of Enviolpjcs, Cassida, Hispa^ Colaspis, etc. 
The other orders of insects received but little attention, and but few 
are contained in i\Ir. Oates's collection. 
Order ORTHOPTERA. 
In this order several large and beautiful species of locusts were 
taken, including AcridiitJii lcp7'osiim and scabrosinn, and Pdasia 
cruentata, Pa/npkagus haploscelis, and the curious wingless grass- 
hopper, Eugaster loricattis of Gerstaecker. Two or three different 
kinds of Crickets and four species of Blattid^ were also taken. 
Order NEUROPTERA. 
In this order a large species of Rlyrvieleon, marked like ]\I. Libcl- 
luloidcs, and the lovely Palpares citrmus, were collected. 
Order HYMENOPTERA. 
In this order two large species of sand wasps with steel blue wings 
were taken. 
Order HEMIPTERA. 
Of Hemiptera twelve species of Cumicidte were taken. 
Order DIPTERA. 
In this order various species injurious to cattle and horses, includ- 
ing six species of Tabanidte, one being the beautiful Tabanus afri- 
canus of Gray (Griff Anim. Kingd. Ins. pi. 114, fig. 5), were taken ; 
also two species of Hippobosca, and various specimens of the terrible 
TSETSE [Glossi/ia iiioi si/aiis, Westw., Proc. Zool. Soc, loth Decem- 
ber 1850), of which I have thought it would be desirable to give a 
fresh figure (Plate G, fig. 2). The figure which I gave of this insect,
