DULICHIUS. 407 



Subfamily III. ALYDINiE. 



Alydina, St&l, Ofv. Vet.-Ak. Fork. 187i>, no. 6, p. 50. 



Bucculse small, short, placed before insertion of antennae ; pro- 

 notum posteriorly not broader or slightly broader than breadth of 

 head, rarely nearly twice, and very rai'ely more than twice as 

 broad ; dorsal surface of first abdominal segment posteriorly 

 rounded, sometimes strongly produced ; scutellum frequently not 

 reaching base of metanotum, somewhat narrower than head 

 between eyes. 



The AlydinsB are almost universally distributed, but are poorly 

 represented in the fauna of British India. 



Division MICIIELYTEARIA. 



Micrelytraria, StFd, En. Hem. iii, p. 84 (1873). 



Pronotum posteriorly not or only a little broader than the head ; 

 the second joint of the rostrum is a little longer than the two 

 apical joints together. 



The JlicreJi/traria comprise some fourteen genera, the majority 

 of which are found in the Neotropical Eegion; the others are 

 distributed in the Palaearctic Region— extending to Japan and the 

 Oriental and Ethiopian Regions. 



Genus DULICHIUS.

 Formicoris, Kirhij, J. Linn. Soc, Zool. xxiv, p. 122 (1891). 



Type, B. trisjnnosus, Stal, an African species. 



Distribution. Ethiopian and Oriental Regioiis. 



Body elongate ; head oblong, longer than the pronotum, before 

 the eyes strongly produced, above very convex ; eyes placed a little 

 behind the middle of the head, very prominent ; rostrum reaching 

 or passing the intermediate coxae, first joint moderately incrassated, 

 shorter than the head, second longer than the first, third and fourth 

 short ; antennae as long as the body or a little longer, fourth joint 

 longest ; base of pronotum depressed and truncate, spined near 

 the lateral angles ; scutellum longer than broad, the apex longly 

 spined ; abdomen subgiobose, much wider than the head or pro- 

 notum, narrowed at base and apex, the lateral angles raised and 

 prominent. 



This genus is very aberrant, and its species strongly resemble 

 or, as is generally expressed, " mimic '' ants ; three species have 

 been described, two of which az"e African and the third belongs to 

 the fauna of British India.
