ALDRICH : DOLICHOPODID.K OP GRENADA, W. I. 87 



Diaphorus contiguus. 



Aldrich, Trans. Lond. Entom. Soc, 1896, 323. 



Eight males, three females. 



Diaphorus spectabilis. 



Loew, Neue Beitr., VIII, 57; Mon. N. A. Dol., II, 162. 



Aldrich, Trans. Lond. Entom. Soc, 1896, 321 (D. approximates, n. sp.) 



Numerous males and females, one labeled "Windsor estate 

 (Windward) , 1500 feet, March 28. Cocoa orchard, on herbage." 

 Comparison with specimens from the United States fully estab- 

 lishes the identity. The only difference between the females of 

 this and simplex is that the latter are, on the average, slightly 

 larger, but doubtless there are individual cases the other way. 



Diaphorus simplex. 



Aldrich, Trans. Lond. Entom. Soc, 1896, 333 (Lyroneurus). 



Numerous males and females. I have explained the change 

 of generic reference at the beginning of the discussion of this 

 genus. 



Diaphorus dubius. 



Aldrich, Trans. Lond. Entom. Soc, 1896, 324. 



Five males, seven females. 



ASYNDETUS. 



Loew, Centur., VIII, 58, 1869. 



In this genus the essential character is in the costal vein 

 reaching only to the tip of the third vein, rather than in the 

 fracture, or even the evanescence, of the fourth vein. The lat- 

 ter characters vary somewhat, but in all the species there is at 

 least a marked thinness of the last part of the fourth vein. 



Loew considered that the elongated fore pulvilli of the male 

 would keep interruptvs in the genus Diaphorus , under which it 

 was described. The shortened costal vein, applying to both 

 sexes conspicuously, seems to me to outrank the size of the 

 male pulvilli. I therefore place the species in Asyndetus.
