178 DIPTEEA. 



the grey triangles in the discal and fourth posterior cells are coalescent with the grey 

 along the apex of the wing. 



A specimen from Guatemala, Teleman, Vera Paz (Champion), has the same characters, 

 and may, perhaps, belong here ; but it is a little larger, 15 to 16 millim. ; the abdomen 

 has parallel sides, while in D. jalapensis it is slightly coarctate ; and although the grey 

 shadows are much more intense, the anal and axillary cells are free from them, which is 

 not the case in D. jalapensis. The Mexican D. pseudojalapensis, Bellardi, Saggio &c, 

 Append, p. 25, is an allied species. 



8. Diogmites ? 



Eab. Panama, Bugaba (Champion). 



I have a male and a female from the above locality, about 23 millim. long. I com- 

 pared them with the types of D. tematus, Loew, in that author's collection in Berlin. 

 They are a little larger ; the palpi are black and not reddish ; the tarsi, except the first 

 joint, black ; the ocellar- tubercle black. 



The following previously described species also belong to this genus : — 



Diogmites angustipennis, Loew, Centur. vii. no. 41. — Kansas; Mexico, Mata- 

 moros. 



Dasypogon (Saropogon) affinis, Bellardi, Saggio &c. ii. p. 73. — Mexico. 



( ) bigoti, Bellardi, 1. c. p. 70. — Mexico. 



( ) brunneus (Wiedem.), Bellardi, 1. c. p. 67. — Mexico. 



( ) craverii, Bellardi, 1. c. p. 68.— Mexico. This species will be 



hardly recognizable ; the two typical specimens were in a very bad con- 

 dition at the time when they were described. 



( ) dubius, Bellardi, 1. c. p. 74. — Mexico, Cuantla. 



( ) goniostigma, Bellardi, 1. c. p. 65, t. 1. f. 6.— Mexico, Playa 



Vicente. 



( ) nigripes, Bellardi, 1. c. p. 75. — Mexico, Playa Vicente. 



pseudojalapensis, Bellardi, 1. c. Append, p. 25.— Mexico, Tuxpango. 



Dasypogon duillius, Walker, List &c. ii. p. 340, from Honduras, is also a Diogmites, 

 and not represented amongst the species of that genus before me ; it has infuscated 

 wings, like D. sallcei, and is represented by a single specimen in the British Museum.
