498 Mr. W. A. Lamborn on West African Insects. 
3. Anchon decoratum, Dist., sp. n. (p. 516). 
No. 48. Two mature examples, the type at Oxford and 
the paratype in the British Museum, were found together 
in the forest, 1 mile E., Dec. 3, 1911. Two larvae of different 
sizes and probably of 2 different species were captured 
with them, as well as 34 attendant P. aurivillat kasaiensis. 
[The number of the ants suggests that more Membracid 
larvae or imagines were present, but escaped. EH. B. P.] 
E.—PSYLLIDAE, ANTS, AND DIPTERA. 
1. Rhinopsylla lamborni, Newstead, sp. n. (see p. 520). 
No. 61. “ These insects, Rhinopsylla lamborm, are very 
numerous now. The larvae are found, on plants in the 
clearing, in large colonies hidden in a white woolly down 
which is rather sticky. When hunting through this for 
Lycaenid larvae, on Feb. 18, 1912, I came across some 
Dipterous larvae and 2 Dipterous pupae, the imagines 
from which emerged Feb. 24.” 
These 2 Diptera with their puparia have been submitted 
to Mr. KE. E. Austen who informs me that the species is 
Baccha claripennis, Lw. (Syrphidae). 
“On Feb. 25 I found numerous mature forms of the 
Rhinopsylla, and, in the ‘ wool,’ other Dipterous pupae. 
The ant Camponotus maculatus, F., is occasionally found 
obtaining food in the ‘ wool.’ ” 
Seven Diptera bred, Mar. 2-5, from the above-men- 
tioned pupae, have been determined by Mr. Austen as 
Baccha picta, Wied., or a species very near to it. A single 
example of the Trypetid fly Ceratitis punctata, Wied., also 
bred Mar. 2-5, Mr. Austen thinks can only have been 
accidentally present as larva or pupa in the “ wool.” 
The carnivorous larvae of the 2 Syrphidae, on the other 
hand, were just where we might have expected to find 
them. 
The collection also contains a “‘ wool ”’-covered mass of 
nymphs and large numbers of imagines of R. lamborni 
collected Feb. 25-26. Two pairs were taken in covtu.
