TWO INTERESTING MONSTROSITIES. 



BY W. HAGUE HARRINGTON, OTTAWA. 



Many minor malformations of wings, elytra, etc, , have been observed 

 in examining insects, but recently I have met with two monstrosities 

 which seem worthy of record. The first insect is a ^ Foenus tarsitorms 

 Say., given to me by my friend, Mr. Guignard, and captured by him on 

 24th June, 1885. I^ thi^ specimen the left posterior tibia becomes trifid 

 about one-fourth of its length from the base, the side branches diverging 

 at an angle of about 30°. The three portions are symmetrical, of nearly 

 equal size (but slightly smaller than the tibia of the opposite leg), and 

 bearing the terminal spurs, etc. The three tarsi issuing from them are 

 perfect in every particular of size and colour. The femur is swollen and 

 gives an impression of three agglutinated, while the trochanter and coxa 

 are also enlarged. 



The second specimen was noticed a few days ago while I was putting 

 sex labels on some Carabidse, and is a $ Pterostichus lucublafidus Say. 

 In this insect only the last joint of the left middle tarsus is in triplicate, 

 and while the parts are equal in size to one another, they are individually 

 under the normal size. The fourth joint is widened (like three small ones 

 joined laterally), while the remaining articles are somewhat shortened and 

 thickened. The tibia is also sHghtly modified ; the spines being irregular, 

 and one of the terminal spurs flattened and bifid. 



CORRESPONDENCE. 



HEPIALUS QUADRIGUTTATUS. 



Dear Sir : In a letter to me, dated October 7, 1864, the late Mr. 

 Francis Walker wrote as follows : " Your quadriguttatus is, as you 

 suppose, identical with my H. argenteomaadatus van" I have myself no 

 doubt that these two Hepiali are distinct species. In Agassiz's Lake 

 Superior, Harris gives quadriguttatus as the same as the eastern argefiteo- 

 maculatus, which latter Mr. Mead took in the Catskills, N. Y.
