Longicoriiia of Mexico and Central America. 257 



Deliathis Batesi, Gahan. 

 Ann. & Mag. Nat. Hist., ser. 6, vol. ii., p. 398. 

 Hah. Mexico, Acapulco in Guerrero (Hoge). 



The single specimen sent by Herr Hoge presents all the 

 chnracters of the two examples from which the species 

 was originally described. For these two examples no 

 more precise locality than Mexico was known. 



The species is easily to be recognised by the uni- 

 colorous yellowish tawny pubescence of the elytra, which 

 is interrupted by numerous rounded shining black spots. 

 The mesosternal process is only slightly produced for- 

 wards at its antero-inferior border. 



Deliathis diluta, sp. n. (PI. XH., fig. 11). 



D. buqueti similis sed vittis fulvis elytrorum pallidioribus, 

 maculisque nigris glabris majoribus, et prgecipue mesosterno antice 

 recto, non producto. J . Long. 32 — 40, lat. 10 — 11-5 mm. 



Hah. Mexico, Amiila, 6000 ft., and Omilteme, 8000 ft., 

 in Guerrero {H. H. Smitli) ; Acapulco [Hoge). 



This species somewhat resembles D. Buqueti, Tasle, in its style 

 of coloration. The pubescence of the elytra consists of two very 

 pale tawny-yellow longitudinal bands on each elytron, alternating 

 with two of a bluish white colour. These bands are much inter- 

 rupted by rather large, more or less rounded glabrous black spots, 

 so that in some specimens their character is not so evident, the 

 pubescence in such cases appearing in the form of irregular reticu- 

 lating patches. 



The species may be distinguished from D. Buqueti 

 and allied forms by the structure of the mesosternum ; 

 this has its ventral face horizontal, its anterior face 

 vertical, so that the angle between them is almost 

 exactly a right angle, being usually slightly less, some- 

 times a little greater. 



In D. Batesi and D. indchra the mesosternum is dis- 

 tinctly, though occasionally but slightly, produced for- 

 wards at its antero-inferior angle ; in D. Buqueti it is 

 more strongly produced forwards ; while in D. nivea it 

 is so strongly directed downwards and forwards as to 

 form a large and conspicuous tubercle.
