188 ALBATROSS EXPLORATIONS, INSECTS HOWARD. 



Family BLATTID.E. 

 Blabera limbata (Burin.). 



A single specimen from Panama belongs here. 

 Nyctobora ? holosericea ? Kl. 



Two immature specimens of a cockroach from Panama are placed in 

 the genus Nyctobora and referred to holosericea Kl. with doubt. 



HEMIPTERA. 

 Tetyra farcta Gerraar, (Pachycoris). Zeits. I, p. 92. 



No. 20. Pachycoris guttipes Walker, Brit. Mus., Cat. Hem., i, p. 47, No. 11. 



One female from Panama. It has the antero-lateral margins of the 

 pronotum a little more expanded than in the normal Mexican speci- 

 mens, and the black dots much reduced in size. 



Augocoris sexpunctatus Fabr. (Cimex), Spec. Ins., n, p. 339, No. 7. 

 Augocoris sexpunctatus Sfal, Enuui. Heinipt., i, p. 18, No. 2. 



Two males were taken on board the ship at electric light, latitude 

 4° 18' N., longitude 85° W. The smaller one is suffused with rose color 

 on the upper side, and it is evidently immature, with the exterior in- 

 tegument imperfectly oxidized, and consequently it would have been 

 dark colored if allowed to reach maturity. It is remarkable for having 

 the rostrum very nearly as long as the body. The tip of this organ as 

 now resting reaches almost to the end of the anal segment, but if set 

 flat against the venter it would reach quite to the extremity of that 

 segment. 



Augocoris ehrenbergii Germar, Zeits., I, p. 140, No. 2. 



One male from Panama, captured on board ship, March 6. It is only 

 in deference to the views of my friend, the late Dr. Carl Stal, that I 

 retain this species as separate from the preceding. The length of the 

 rostrum is now observed to be of no value in separating the species 

 of this genus. 



Family COREHLE. 

 Catorhintha guttula Fabr. (Lygams), Ent. Syst,, iv, p. 162, No. 92. 



A single immature female was collected at Panama. It is larger than 

 the typical specimens from the West Indies and Central America, has 

 the anteuniferous spine longer and more curved, and one of the spines 

 is wanting on the right-hand side. 



MALLOPHAGA. 



(On Diomedea exulans). 

 Two species of Lipeurus. 



Lipeurus taurus Nitscb. 



Many specimens of males, females, and young.
