wrongly separated the sexes of many species as distinct, and adopts an 
arrangement employed in his former essay (Abh. Ges. Halle ii. 1854,

including M. perspicillaris^ Klug, and spinosa^ Sweder. ( ^ = corpulenta^ 
Gerst.) ; 2, Pedunculatae, if. trinacria, dupUcata, and miniata, Gerst., 
tristis and parallela = characterea, Gerst.), Klug, and four new 
species ; 3, Capitatae, if. hcamatodes and diaholica, Gerst., and one new 
species. Division II., Megalocratin^ ; sub-d. 1, Pendulae, if., armata, 
miles, megacephala, and cephalotes, Burm. (of which last, erythraspis, 
Gerst., is probably the ^ ) ; 2, Subsessiles, if. sumptuosa, Gerst. ( ^ = 
dulcis, Gerst.), and two new species. Division III., Helophthalm^e ; 
sub d. 1, Carinatas, if. fronticornis, Burm., cerasina, amahilis, pythagorea,

Scaptodactyla, g. n., H. Burmeister, Z. c. pp. 499-502. Does not enter 
into any of the divisions employed by the author as above mentioned, 
but forms a separate group, approaching if. tenuiventris, Spin., in the $ , 
and Bradynohcenus, Spin., in the $ , which the author queries as them- 
selves probably referable to one genus. Male almost Thynni-form, very 
slender, and female thicker than any other indigenous species, having 
also fossorial setae on the outer edge of the front tarsi, and the middle 
and posterior tibiae with a triple series of spines externally. S. hetero-

C. Emery, Ann. Mus. Genov, vii. pp. 465 et seq. & 895, briefly discusses

workers of Stigmatomma denticulatum. Hog., and inipressifrons, Em., and
