Fig. 11—Hygronemobius speculi (McNeill). Dorsal outline of male 
subgenital plate and chitinous projections of titillator. Type. Tagus Cove, 
Albemarle Island, Galapagos Islands. (X 26) 
Examination of the two adult males and twenty immature in- 
dividuals of McNeill’s series shows this species to be closely 
related to, but distinct from, H. dissimilis (Saussure). Our 
assignment of speculi to synonymy under dissimilis*® is there- 
fore erroneous. 
We here select as type of speculi a male before us, belonging 
to the Leland Stanford Jr. University, taken at Tagus Cove on 
Albemarle Island, Galapagos Islands, on January 23, 1899. 
Compared with males of dissimilis in the Philadelphia collec- 
tions from Petropolis, Brazil, the following differences are 
noted. Maxillary palpi yellowish brown, with apex only of 
last joint suffused with a darker brown. Tegmina almost uni- 
form dark brown, the veins and distal portion of the dorsal field 
being only very slightly paler’’. Dorso-internal spur of caudal 
tibia equalling metatarsus in length. Titillator developed into 
two elongate slightly inbowed arms, the apices of which reach 
26 Ent. News, XXVI, p. 197, (1915). 
27Tn the males of dissimilis before us the tegmina are as dark, with principal veins 
and broad caudal marginal portion of dorsal field strikingly buffy.
