clearings, but other insects must be searched for, and to secure 

 them great labor is required. The diurnal Lepidoptera from 

 that country are well known ; the Heterocera, on the other hand, 

 are very rarely seen and appear to be very scarce. The fami 

 lies of Coleoptera which are well represented are the Chrysome- 

 lidse, the Cerambycidse, and the Curculionidse. Of these, the 

 Chrysomelidse are conspicuous and very numerous, both in 

 species and individuals. The Cerambycidse, although well rep 

 resented, are not conspicuous and must be searched for. The 

 Curculionidae, also, are not obvious, but are nevertheless well 

 represented. There appear to be no large bright colored Dip- 

 tera. Some Tipulidse mimic hymenopterous parasites and are 

 quite conspicuous. Man-attacking Diptera are very abundant, 

 and are represented by black flies (Simulium), sand flies, mos 

 quitoes, Tabanidae, Hippelates, and the psychodid Flebotomus 

 exhibited earlier in the meeting by Mr. Barber. Antidotes and 

 repellents are not of much account against them, and the latter 

 are soon dissipated in the open air. On the whole Mr. Schwarz 

 thought that the Diptera were not well represented as regards 

 number and variety of species. Forficulidae were abundant and 

 in great variety, as were also the roaches and crickets in the 

 Orthoptera, and the katydids. Strangely enough they found 

 not a single native dytiscid beetle. Dragonflies and other in 

 sects belonging to the neuropteroid orders were poorly repre 

 sented. There was a remarkable absence of fleas, though the 

 sand flea (Sarcopsylla) occurred on the sand of the coast at 

 Puerto Barrios ; no bed bugs were seen or heard of, and Mr. 

 Schwarz stated that the driver ants (Eciton) constituted a 

 capital enemy of all household insects. 



In conclusion Mr. Schwarz exhibited a collection of photo 

 graphs of Guatemala scenery taken on the trip by Mr. Barber.
