process, but becoming coarser, denser, and somewhat confluent at 

 the sides and along the anterior margin, sparsely clothed with fine 

 erect hairs; anterior margin broadly but not deeply arcuately 

 emarginate in front, with the margin strongly elevated; prosternal 

 process short, moderately broad, feebly convex, and without mar- 

 ginal grooves, the sides nearly parallel to the middle of the anterior 

 coxal cavities, where they are emarginate and abruptly narrowed, 

 the apex broadly rounded. 



Length, 18-21 imn. ; width, 7-8 mm. 



Described by Jacquelin Duval (1857) from Cuba. Chevrolat 

 (1867) records it from the central part of the same island from 

 material in the collections of Gundlach, Poey, and Chevrolat. Gund- 

 lach (1891) records collecting specimens at Cienfuegos, and also at 

 Caimanera near Guantanamo, both localities in Cuba. 



Material has been examined of this species as follows. Coll. 

 British Mus. : Tavo females, one labeled "Cuba (Poey)" and marked 

 type, the other simply labeled "Parry (Saunders 74-18)." Coll. 

 Acad. at. Sci. Philad. : One female,' Cuba (Poey Coll.). Coll. 

 Amer, Mus. Nat. Hist. : One female, Guantanamo, Cuba, collected 

 June 11, 1910, by Chas. T. Ramsden. Coll. U. S. Nat. Mus.: One 

 female, Guantanamo, Cuba, collected June 26, 1915, by Chas. T. 

 Ramsden. (Donated by Amer. Mus. Nat. Hist.) There is also a 

 specimen in the collection of the Acad. Nat. Sci. Philad., labeled 

 "Cuba (Poey Coll.)" which I have placed under this species. It 

 is a very small specimen measuring only 11 millimeters in length 

 and 4.5 millimeters in width, and which agrees in every way with 

 the other specimens of this species examined, except in size. It 

 is a male and has the usual densely punctured and pubescent median 

 spot on the first abdominal segment. There is a single example 

 labeled No. 807 in the Gundlach Museum in Havana which has 

 not been examined by the writer. 



Kerremans has placed this species as a synonym of excavata de- 

 scribed by Blanchard (1846) from Argentine Republic, but since 

 these localities are so widely separated and the species has not been 

 reported from any intermediate localities, I am retaining the name 

 angulosa for the specimens collected in Cuba. This species is closely 

 allied to porcata Fabricius, but it is more slender, head more 

 densely and coarsely punctured, anterior margin of pronotum not as 

 deeply emarginate, abdomen beneath more finely punctured and more 

 densely pubescent, prosternum more densely punctured, and the 

 prosternal process much narrower in proportion to its length than 

 in porcata.
