forms must be established by the collection of large series, before a stable 

 nomenclature for the group as a whole can be even suggested. For 

 instance, the //aj^iaia of Stal and the malleifera of Fowler apparently 

 belong to the same specific group, being very close, structurally. 

 Malleifera as it occurs in Nicaragua, Mexico and Belize, is extremely 

 variable. The species of true Acutalis are also remarkably variable and 

 equally worthy of collection and investigation. 



Darnid.*. 



Darnoides fiavescens, n. sp. 



Length, about 4.5 mm. This is a pale yellowish-brown species with 

 an evenly-rounded, not at all raised pronotum, which is evenly, coarsely 

 punctate, and its acute point tipped with black. The sternum is 

 blackened. The tip of pronotum reaches the end of clavus. Thetegmina 

 are glassy hyaline, the nervures are pale at base to dark at tip; at extreme 

 base of clavus, and of corium between ulnar vein and costa, the substance 

 of the tegmina is coriaceous and strongly ininctate, the i)uncturing 

 extending outward some distance along the veins. The claval 

 nervure is not half the length of the clavus. The terminal veins are nearly 

 straight except the second from costal margin, which is distally bent 

 towards the costa. There is a single large discoidal cell formed by a cross- 

 vein between inner and outer ulnar veins before the middle of tegmina. 



This species was collected in Belize, British Honduras, by a former 

 student of mine, Mr. J. D. Johnston. 



Damoides seinicreina, n. sp. 



There occurs not uncommonly in the vicinity of Havana, a small 

 membracid which bears a remarkable resemblance to Acutalis seinicreina, 

 and possibly may be found in some collections under that name. It is, 

 however, shorter and more robust, and differs wholly in its family and 

 genus characters. I cannot find that it has been described. Even if I 

 make a synonym, however, I trust that it will be a readily recognizable 

 one. It is sometimes necessary to make a synonym in order to properly 

 elucidate and bring to light some of the ancient and illy defined species 

 which would otherwise remain merely stumbling blocks in our literature. 



Length, 4.5 mm.; width across pronotum, 2.25 mm. Leg>, sternum 

 and abdomen of varying shades of shining piceous, lighter on dorsum and 

 on tibios and tarsi. The abdominal segments are narrowly margined with 

 paler. The sternum anteriorly and a large spot on sides of metathorax 

 are more or less white waxy pruinose, the latter siioi showin*.', through the 

 costal base of tegmina. The head is very short and broad, the vertex
