sents the transition to P. americana. The specimen figured l>v de 

 Bormans [1903, pi. 1, fig. 5] lias spotted elytra, and is probably 

 referable to P. americana or P. pulchra. 



4. CINCTICOLLIS Gerstaecker. 



Afric-a.- Liberia, Mount Coffee, three males and one female (K. P. 

 Currie). 



I have recently shown [1909 5 ,p. 113] that Brachylabis cincticollis of 

 Gerstaecker is the nymph of Psalis picina Kirby, so the true name of 

 this species is Psalis cincticollis (Gerstaecker). 



5. NIGRA Caudell. 



Trinidad. — Montserrat, July 4, 1905; a single female taken by 

 Busck. (Cat. No. 10290.) Caudell's type (1907 1 ), p- 167. 



It is unfortunate that the male is unknown. The almost square 

 pronotum, rounded posteriorly, and the short, thick antenna! segment 3 

 are the most distinctive features. 



It appears to be allied to P. gagatina Bormans and the African 

 P. cincticollis Gerstaecker. 



Genus ANISOLABIS Fieber. 



1. ANNULIPES Lucas. 



Mi xico. — One female. 



Mexico. — Minatilan, February 1, 1902 (II. Osborn), one female. 

 [See Rehn, 1903 2 , p. 304.] 



Mexico. — (Duges), two females. One specimen is determined by 

 Rehn as A. antoni Dohrn, but I consider that species identical with 

 A. annulipes Lucas. [See Rehn, 1903'-, p. 305.] 



Paraguay. — Sapucay (W. F. Foster). Caudell's originals of A. 

 azteca [1904, p. 180], which I also consider synonymous with .1. 

 annulipes, as has been suggested by Rehn [1 '.>()(>, p. TO!)].' 4 



Hawaii. Honolulu, three males, five larvae (Kotinsky). 



California. (C. V. Riley), one female. 



Algeria. — "On a date palm;" labeled "An. mauritanica Lucas, I 

 believe." 



Guatemala. Chiantla, one female. 



Cuba. — Baracoa, one male, September (Busck). [Caudell, 1907 1 , 

 p. 168.] 



Porto Rico. — Fajardo (Busck). A line female. [See Rehn, 1903 4 , 

 p. 1L'!).] 



Florida. Crescent City (C. A'. Riley), one male. "New Orleans, 

 La" (Shufeld) (C. V. Riley), one female. 



Guadeloupe. A. bormansi, Scudder's type; female, Guadeloupe, 

 undoubtedly referable here; agrees with Caudell and Rehn. 



"I have since seen Dohrn's types of A. azteca; ii is a good species, probably ;i 

 Gonolnhis: l ho so-called A. azteca of literature arc. however, probably all referable 

 to A. annulipes: Dohrn's type of A. antoni is certainly indistinguishable from 

 A. annulipes.
