52 NOTES ON JAMAICAN HEMIPTERA 



ii, pi. 7, fig. 25. In the female of this species the elytra are 

 narrowed to an acute apex much as in Polyglypta. 



Subfamily Darninae 



I took quite a series of what I believe to be varieties of one 

 species belonging to this subfamily. Of the 23 specimens taken 

 hardly two are alike. They vary in size as well as pattern of 

 marking, but all are small. 



Subfamily Centrotinas 



Callicentrus aurifascia Walker. (Cat. of Homop. p. 618.) 



At Montego Bay I took one female that I believe should be 

 placed here. This specimen has nearly the whole front of the 

 thorax bright yellow, and wants the "stripe of pale yellow 

 down each side of the breast" and the "bright yellow stripe 

 each side beneath the abdomen'. It also differs in the color of 

 the tibiae and in the presence of the band of white tomentum 

 on the sides of the pleural pieces. Pyramba aurifacies (n. gen. 

 et sp ) Buckton (Monograph p. 248.) is a closely allied species, 

 but apparently wants the white spot on the base of the corium 

 and has the posterior process of the pronotum extended to the 

 apex of the closed elytra. Buckton's genus Pyramba is cer- 

 tainly identical with Callicentrus Stal but it would not be valid 

 in any case as he gives no indication of the characters on which 

 he purports to found it. Buckton's Monograph is almost worth- 

 less for determination ; his figures are unrecognizable and the 

 descriptions, so far as I have had occasion to make use of them, 

 are no better, while his nomenclature in places is positively 

 weird. It would be a boon to all students of this group if some 

 entomologist who understands the characters of the Membra- 

 cidae would go over Buckton's types while they are still acces- 

 sible and tell us what they really are. 



Callicentrus jucundus Walker. (Cat. of Homop. p. 620.) 



I took one male at Montego Bay that agrees in every essen- 

 tial particular with Walker's description. Another male taken 

 at Balaclava, April 4th, differs in being a little larger, of a uni- 

 form ferruginous brown color on the head and pro thorax and in 

 having a longer and more protracted head with its apex more 

 rounded. The legs also are paler in color and the humeral 

 angles are more rounded and prominent. It does not agree
