capable of squirting a strongly acid liquid, the latter in the so called 

 " Mutilloid " Carabidae and Cicindelida?, where two species of Carabidae 

 or a species of Carabidse and one of Cicmdelidse, etc., may resemble the 

 shape and markings of a species of Mit/illa, all three living in the same 

 locality at the same time. " By far the most complete illustration hitherto 

 known of the power of mimicry to attract all forms irrespective of affin- 

 ity " is that afforded by the " group with Lycoid markings," 36 species 

 of Coleoptera, Hymenoptera, Hemiptera. Lepidoptera and Diptera of 

 Mashonaland whose brown and orange markings (figured in Plate 

 XVIII) resemble those of seven species of Lycidae (Coleoptera). 



Still another section deals with common warning colors in South 

 African Hymenoptera a-nd the mimicry of them by insects of other orders. 



If the notice we have given of this highly interesting and suggestive 

 paper appear to some to be of undue length, our justification may be 

 found in these words of Mr. Marshall in speaking of his experiments : 

 " I feel convinced that were naturalists more ready to carry out extensive 

 experiments of this nature there would be much less of the prevalent 

 a priori criticism of these valuable theories [of warning coloration and 

 of mimicry] which throw light upon a vast number of facts which must 

 otherwise remain for us mere meaningless coincidences. It is especially 

 important that experiments should be made by as many different ob- 

 servers as possible, for in this way alone can the errors due to unavoid- 

 able personal bias be eliminated ; and if the present publication only has 

 the effect of inducing other entomologists in South Africa, or elsewhere, 

 to turn their attention to the interesting problems involved, it will have 

 fully served its purpose."

 entomologists " ! P. P. C.
