species. Further comparison of these, however, indicates their 

 identity with T. acutipennis. This indicates a very wide dis- 

 tribution of the species. 



Tenaphalara fascipennis Crawford.

The study of several newly discovered species of Malayan 

 psyllids evidently related to Tenaphalara has led me to group 

 together in this genus not only these new species but also the 

 related and more or less intermediate Philippine form for the 

 reception of which a new genus had been erected, Strogyloce- 

 phala. As this was a monotypic genus, this name becomes syno- 

 nymical with Tenaphalara. 



Luzon, Laguna Province, Los Banos. 



Tenaphalara malayensis sp. nov. Plate II, fig. 3. 



Length of body, 3 millimeters; forewing, 3.3. General color 

 flavous to fulvous ; thoracic dorsum with slightly darker streaks ; 

 vertex brown ; antennal segments 3 to 10 black or brown ; front 

 and middle tibia brown; eyes black. 



Head about as broad as thorax. Vertex a little broader than 

 long, quadrate, with posterior ocelli elevated and a prominent, 

 hornlike, flattened epiphysis on each side between antennal base 

 and posterior ocellus. Genas swollen beneath antennal sockets 

 and slightly protruding roundly in front of vertex, covering 

 f rons ; clypeus long, narrowly rounded at apex ; beak long. An- 

 tennas about four times as long as width of head, closely approx- 

 imate at base, segments 1 and 2 short and not very thick, but 

 segment 3 distinctly thicker than succeeding segments. Eyes 

 prominent. 



Thorax narrow. Legs long and slender; hind tibise with a 

 large spur at base and four black spines at apex. Forewings 

 hyaline, clear, venation as in congeners, but pseudovein between 

 radius and radial sector often wanting. 



Abdomen long. Male forceps short, slender, subacutely 

 pointed; anal valve shaped somewhat as in Aphalara, with a 

 cau dally directed lobe which is nearly as long as basal width. 

 Female genital segment about two-thirds as long as abdomen; 

 valves subequal in length but dorsal blunt at apex and ventral 

 very acutely pointed; dorsal valve with a single horizontal row 

 of twenty or more hairs around end ; ovipositor stout, exserted.
