From some Angolan specimens bred from eggs by the writer, 

 however, appears the remarkable fact, already discussed by me 

 in another publication, * that the $ $ do not share this pecul- 

 iarity. In these there is no true scaled seventh vein, but the 

 sixth is bent at right angles near the edge of the wing. This 

 instance serves to illustrate the dangers of sweeping systematic 

 conclusions founded upon restricted data. H. simplex occurs 

 in great numbers in the rainy season, usually in company with 

 other mosquitoes, especially Daniclsia wellmani Theob. and 

 Mansonia iinifonnis Theob. It breeds in foul pools, the egg's 

 being brown in color and laid in rafts.

It is well known that the larvae of some Lepidoptera defend 

 themselves by means of stinging hairs. For instance, we have 

 I:niprctia stimulea and Aittoincris io in America. In Angola 

 there are a number of caterpillars with this habit. Three of 

 these are especially venomous and belong respectively to the 

 Limacodidae (Micro), Arctiidae (Macro) and Liparidae (this 

 latter resembling rather closely the larvae of some Tortricidae). 

 I have repeatedly tried to breed out these caterpillars, but have 

 never succeeded. I have seen the Limacodid larvae very often 

 in spots haunted by imagines of the species named at the head 

 of this note, and have therefore provisionally connected the 

 two forms. This caterpillar is locally called "Epnvi" and 

 stings terribly. I once saw a severe case of urticaria in a 

 white child following one touch of it.

This giant cricket is dug out of its burrows in mealie fields 

 by the native women, often in great numbers. One can some- 

 times see small basketfuls, wings and legs removed, ready for 

 the pot for they are esteemed a great delicacy. Native chil- 

 dren often go about digging for these crickets, and not seldom
