portion is piceous and is limited by an elevated blunt ridge, but before the apex this 

 inner portion has a deep grooved excision, yellow within, each edge of wliich ends 

 in a broad tooth directed inwardly and upwardly, whereof the upper is shorter 

 than the lower ; inwardly below the lower of these teeth is a very deep excision, 

 followed more inwardly by a long and strong acute tooth, slightly curved and di- 

 rected inward and downward, with small tubercles on its inner edge. (Thus these 

 appendages are trifid at the apex inwardly if viewed fi-om above, but only bifid if 

 viewed from beneath, the shorter of the two outer teeth not then being visible ; the 

 whole arrangement is exceedingly complex). Inferior appendage one-half shorter, 

 slightly longer than broad, and slightly narrower at the apex, which is shallowly 

 excised, with upturned angles if viewed laterally. In the ? the appendages are 

 short (5 mm.), long-oval, flattened, obtuse, brown plates, with a raised central longi- 

 tudinal keel extending from base to apex. Valvules scarcely exceeding the 9th 

 segment, ending in short, curved, cylindrical appendages, each of which has a 

 bristle-like second joint. 



Hahitat : North California {WaJsingham), and Guatemala. 



Several examples were captured by Lord Walsingham, and the de- 

 scription has been made from a pair which have long borne the above 

 name in my collection, but the species has never been described. A ^ 

 from Guatemala has been still longer in my collection ; it is mutilated 

 (wanting the apical half of the abdomen), but agrees entirely with 

 the Californian (^ , excepting that there are only IG antecubitals in 

 the anterior wings (10 postcubitals) ; the size is the same. 



This very fine insect agrees somewhat with the American A. 

 Junius and amazili in the design of the top of the front, but there all 

 resemblance ceases, its excessively long slender abdomen, and very pe- 

 culiar anal parts in the ^ (which have no parallel), being especially 

 characteristic. 



N.B. — Hagen, in his "Synopsis of the Odonnta of America*' 

 (Proc. Bost. Soc. Nat. Hist., 1875), indicates an A. validus from San 

 Diego, California. This I strongly suspect of being identical with A^ 

 Wahinghami, but no description has ever been published. 



Anax Eutherfordi, n. sp. 



I possess two males of a reddish-brown Anax from Sierra Leone 

 {Btitherford) so similar to A. speratus, Hag. (Yerh. z.-b. Ges. Wien, 

 1867, p. 46), from the Cape of Good Hope, that I was at first disposed 

 to identify them therewith, according to the description of the latter ; 

 but there are certain discrepancies which induce me to retain my 

 specimens as distinct, and I propose for them the above name. It 

 appears to me that a tabular view of the discrepant points will suffice, 

 and in giving this I retain Hagen's original words.
