that there were at least six caterpillars in every square foot for the 

 entire distance. Leaving my team I climbed the ridge to learn, if 

 possible, why they were thus congregating on a spot so entirely de- 

 void of vegetation. I saw at once that their well known habit of 

 travelling in a northerly direction was getting them into trouble. 

 The beach at this point bears considerably west of north, and the 

 caterpillars on reaching the edge of the bluff would roll down to the 

 beach, from whence it was impossible to return. Even here they 

 turned neither to the right or left, but persistently crawled on to the 

 water's edge, where each receding wave would carry out dozens, 

 only to bring them back dead and pile them up in ridges on the 

 beach. In places these ridges of dead caterpillars would be fully 

 four inches high. After driving two miles or more we found the 

 beach suddenly clear of them, the line here being as well defined as 

 on the south side, where we first approached them. While watching 

 them I went inland seventy-five feet or more into the palmetto scrub. 

 Here they were not nearly as thick, but there were a great many on 

 the ground, and all travelling in the same direction."

AGALLISSINI. 

 The characters of this tribe are stated in Bull. Br. Ent. Soc. vii, 

 p. 114, and are fully discussed in the "Classification" p. 306. It 

 contains only two species, both very rare in collections, viz. : 



Agallissus gratus Lee. 



Leiii^th 19 mm. = .75 inches. Habitat. — Texas. 



Shining black, sparsely punctured, with the elytra narrowed 

 behind, truncate and finely serrate at tip, ornamented with yellow- 

 spots, of which the basal pair are elongate. Front quadrate, ob- 

 lique ; prothorax rounded on the sides ; sutural spine of elytra mod- 

 erately prominent. Antennae slender, shorter than the body in both 

 sexes. 



Zagymnus clerinus Lee., .S. M. C. No. 264, p. 203. 

 Length 13 mm. = .52 inches. Habitat. — Florida. 



Opaque black, very coarsely and deeply punctured with the 

 elytra parallel on the sides, rounded at tip, with a round basal spot
