Ants from British Guiana. 377 



Appendix. 



Tlie following species liave previously been collected In 

 British Giiianu, and identified by the Inipeiiul Bureau o£ 

 Entomology : — 



Paropcnera clavafa, F. 



" A fairly common species. The local name is ' Muniri.' 

 Formiearium observed on two occasions at the base of 

 young trees. The soil is carefully cleared away from around 

 the base of the trunk to a considerable depth, and this serves 

 as the means of communication to the nest. It is only 

 necessary slightly to tap the trnnk of the tree, when the ants 

 swarm out makinjj the stridulati(i<r noise common to the 

 species. They soon return to the nest, however. The sting 

 as exceedingly painful, and will bring on fever in a susceptible 

 individual." 



Odontomachus hcematoda, L. 



0. affinis, Guer. 



Eciton burcJielliy "SVestw. 



E. caecum, Ltr. 



Crypiocerus clypeatus, 01 i v. 



'' A fairly common species. The formicary has once been 

 observed beneath the loose decaying bark of a tree ; the 

 community consisted of about 1000 individuals." 



Atta fervens. Say. 



" This species seems occasionally to occur in the interior 

 districts ; it has never been taken near the coast." 



Camponotus niaculatus, F., subsp. picipes, Oliv. 



JS^ote on Claviger testaceus. 



Donisthorpe has recently (Ent. T?ec. xxviii. 2, p. 34, lOlG) 

 commented on my experiments with this myrmecoj)hilou3 

 beetle and the queens of Lasius niyer, Jiavus, and umbratus 

 (Ent. Rec. xxvii. 9, p. 205, 1915). My remarks, owing to 

 their brevity, have evidently given rise to a misapprehension. 

 The beetle?, as I have {ueviously observed niysell, sometimes 

 rest on the queens in nests of L. Jiuvus, their normal host.
