 Genus Cyclokaka Muir. ' 



In niY table of genera of Derbidae'' I placed Patam West, 

 in Gronp II. Westwood's figure was not clear to nie at thatj 

 time, bnt since then I have examined allied forms from the 

 West Indies and now see that Patam should have been placed 

 in Group I, as it conies near to Cydol-ara Muir. Daivnaria\ 

 Distant is close to Cydol-ara. Patara West, differs from both 

 of these in having a large, flattened antenna. I place Paiara 

 vanduzei Ball in Cyelol-ara but the neuration is not (piite 

 typical. 



C. sordid iihi in sj). nov. 



$ In neuration, shape of head and antennae this species is typical 

 of the genus. Head, thorax and abdominal sternites sordid pale orange 

 yellow, carinae of face between eyes slightly infuscate, abdominal tergites | 

 cadmium orange. Tegmina sordid yellow, opaque with waxy secretion, | 

 slightly fuscous over apical cells, veins brownish in places ; wings white i 

 opaque with waxy secretion, veins brown. 



Edges of pygophor straight, entire, with a small, sharp point pro- 

 jecting on each side of the anal segment; anal segment small, about as 

 long as wide ; styles large, broad, apex roundly truncate, ventral edge 

 slightly convexly curved, roundly produced in middle, dorsal edge very 

 slightly and concavely curved, with a quadrate projection on basal half. 



Length 2.1 mm.; tegmen 4.5 mm. 



2 Similar to male. Anal segment very small, as long as broad; 

 pregenital ventral plate short, posterior edge widely angularly produced, 

 the apex of the. projection turned slightly dorsad. 



Length 2.2 mm. ; tegmen 5.5 mm. 



Tlab. Porto Rico, Aibonito, Mayaguez, July, 1914. De- 

 scribed from five males and five females. Type in the Ameri- 

 can Mus. of Xat. Hist., Xew York. 



Genus Persis Stal. 



The following species agrees with Stal's description of the 

 ffenus. It has a similar neuration but the head is much more 

 acutely angular in i)i-ofile and tlie shoulder keels are only re])- 

 resented by a ridge. It differs froui Goneol'ara Muir in having 

 the head more produced, in profile the vertex and face form an 

 acute angle, and the tegmen is longer and narrower.
