but of this number five proved to be new. The others occur in 

 St. Vincent and Cuba. 



In the family Braconidce some twenty-nine species were taken, 

 representing seven new and twenty-two described species. Of the 

 twenty-two described species, twenty have already been reported 

 from St. Vincent, while two, Macrocentrus delicatus, Cr., and Hor- 

 mius melleus, Ashm., occur in Florida and other parts of the TJnited 

 States, and are now reported for the first time from the West 

 Indies. Macrocentrus delicatus, Cr., is also found in Mexico. 



The two other families mentioned — the CynipidceSLudthe Procto- 

 trypidce — were exceedingly rich in species, the vast majority of them 

 being microscopic in size and difficult to study. 



In the family Cynij)idce no less than seventy species were 

 recotmized, all belonging to the parasitic subfamily Eucoelince. It 

 is worthy of note that, up to the present time, not a single gall- 

 making species in this family is yet reported from the West Indies,— 

 the species reported and described by Cresson from Cuba, and 

 supposed to be true gall-makers, being all parasitic forms. 



Of the seventy species mentioned in this report, eight only were 

 described, and these are from St. Vincent '. All the others are 

 apparently new. These are distributed in eighteen genera, of 

 which five are new. 



The family Proctotrypidce is represented by seventy-five species 

 distributed in twenty-nine genera, only one genus being new. Of 

 the species twenty-one have been described. Two species, Aphe- 

 lopus albopictus, Ashm., and Ceraphron hasalis, Ashm., occur in 

 the United States, while all the others were quite recently described 

 from St. Vincent. 



The six new genera and one hundred and twenty-eight new 

 species of parasitic Hymenoptera described in this report admirably 

 illustrate the wonderful richness of the West-Indian fauna, and 

 the amount of work yet to be done before sufficient data will have 

 been accumulated to afford a basis for a safe generalization upon 

 the distribution of these insects.
