NEOBROTICA AND RELATED GENERA — BLAKE 307 



breast darker, elytral spots with a faint metallic lustre: a spot on the 

 humerus, one about the scutellum, one on the side below the humerus, 

 and a horizontal one before the middle, and one on the side and 

 another in the middle near apex on each elytron. 



Head with interocular space less than half width of head, frontal 

 tubercles distinct and a median depression above them, occiput 

 smooth, alutaceous, minutely punctate, a narrow carina down the 

 front; entirely pale in some specimens, brown to piceous in others. 

 Antennae pale. Prothorax not twice as wide as long wdth slightly 

 rounded sides and a transverse sulcus, shining, very finely and in- 

 distinctly punctate, pale. Scutellum pale. Elytra alutaceous with 

 strong dense punctation tending to be geminate striate between the 

 feeble costae, pale yellow with dark markings usually with a vio- 

 laceous lustre and consisting of a dark humeral spot, sometimes 

 united across the base with a dark area about scutellum, the latter 

 extending down the suture a little way but not meeting the trans- 

 verse short fascia below; this fascia sometimes broken into a short 

 horizontal mark and a lateral spot, near the apex a median and 

 lateral spot, sometimes united in a semilunate mark. Body beneath 

 and legs pale, the breast deeper brown, the anterior tibiae in male 

 enlarged. Length 5.4-5.9 mm.; width 2.7-3 mm. 



Type, whereabouts unlmown, from Trinidad. 



Other localities: Montserrat, Trinidad, collected by Augustus 

 Busck, June 1903; Cocoa estate about six miles from LaBrea, Oct. 18, 

 1918, collected by H. Morrison; Dept. Agricultm-e grounds, Port-0- 

 Spain, November 1918, collected by H. Morrison; Tobago Island, 

 collected by A. Busck. 



Remarks: In the Bowditch collection specimens of this species 

 have been placed under A^. coeruleolineata Jacoby, which is found in 

 Mexico and Guatemala and has similar elytral markings. In the 

 British Museum (Natural History) is a series of seven specimens, 

 all from Trinidad and very constant in markings, that is labelled by 

 Gahan with the manuscript name trinitatis. Bechyne has labelled 

 the one specimen in the Frey museum, also from Trinidad, as Neo- 

 brotica dimidaticornis praeclara Weise, a new combination for Cero- 

 toma praeclara Weise. Although I have not examined the type, 

 Weise's detailed description fits this species, and in particular his 

 description of the distinguishing mark in the elytral spotting of this 

 species, "the 2 and 3 spots he in a straight cross row", applies to this 

 species and not to dimidiaticornis. The species appears to be con- 

 fined to Trinidad and Tobago Island.
