6. Fkontal Gynandeomobph of Solenopsis fugax 

 Lateeille. — Santschi (1910, p. 649) 



The head and thorax in this specimen are female, the 

 pedicel and gaster male. The head is somewhat smaller 

 than in normal females. The copulatory organs are those 

 of the normal male. Santschi remarks that it ' 1 would be 

 interesting- to observe the sexual behavior of such an indi- 

 vidual possessing a female brain and male genitalia." 



7. Lateeal Gynandeomoeph (Ebgatandeomoeph) of 

 Myemica scabbinodis Nylandee. — Donisthoepe 

 (1913, p. 44, PI. I) 



A nearly complete lateral ergatandromorph ; worker on 

 the right, male on the left side, the former being blackish, 

 the latter reddish yellow. Eight half of head larger than 

 the left, but with a smaller eye, striatorugose; right an- 

 tenna yellow, with a three- jointed club, its scape with the 

 usual strong lateral tooth at the basal flexure. Eight 

 half of thorax yellow, its epinotal half with a strong spine ; 

 right half of petiole and postpetiole yellow, rugose and 

 punctured ; right half of gaster pale fuscous yellow. Legs 

 on the right side of the worker type, yellow. Left side of 

 head blackish, punctate, not striatorugose, with a larger 

 eye and the median and left ocellus ; its antenna fuscous, 

 with four- jointed club. Left half of thorax blackish, its 

 epinotal portion unarmed; left half of petiole and post- 

 petiole smooth, fuscous black. The greater part of the 

 left half of the gaster had been eaten away but the re- 

 mainder was darker fuscous than the right. Legs on left 

 side of the male type, fuscous ; wings on the left side only. 



Donisthorpe remarks that this specimen, which was 

 picked up dead by Mr. Dollman at Ditchling, England, ap- 

 proaches the var. sabuleti Meinert in having the left 

 antennal scape longer than in the typical male scabrinodis 

 and the tooth on the right antenna large. 



In conclusion I would call attention to a peculiar ant 

 described by Mayr (1868, p. 60) from the Baltic amber
