Diphaglossa is characterized by the peculiarly elongate, triangular 

 head, the face being three times as wide at the vertex, from eye to eye, as 

 at the base of the mandibles along the clypeal margin ; clypeus elongated, 

 twice as long as broad, longitudinally striate ; mandibular space much 

 elongated, punctured, longitudinally striate ; antennae reaching beyond 

 tegulge ; mandibles bifid at tip ; labial palpi 4-jointed, three basal joints 

 subclavate, fourth joint longest, more slender and slightly tapering ; 

 maxillary palpi 6-jointed, joints subclavate, except the last, which is slen- 

 der, slightly tapering, fourth and sixth joints almost equal, second 

 shortest, first longest ; wings with marginal cell slightly appendiculate, 

 ftrst cubital cell longest, but not as long as second and third united, third 

 smallest, narrowed above, first recurrent nervure entering second cubital 

 cell at the middle, second recurrent nervure more or less curved, entering 

 the third cubital beyond the middle ; transverse median nervure entering 

 before radial nervure and weakly angulated ; first joint of tarsi flattened, 

 elongate, claws bifid and with a pulvillus; metathoracic truncation narrow, 

 almost perpendicular, no row of pits present ; abdomen with distinct 

 dorsal and ventral hair bands. 



Spinola has figured the tongue as emarginate and with two pairs of 

 slender "filaments," the apical pair very long. While the tongue is 

 undoubtedly emarginate, the '' filaments" are missing in all of the speci» 

 mens we have examined. However, Dr, Friese states that the para- 

 glossffi are slender and threadlike, extending beyond the tip of the tongue. 

 Spinola states that the mandibles have three teeth, but his figure shows 

 but two, and he also gives the hind tibiae as unispinose. Dr. Friese has 

 corrected this, stating that they are spined as usual, and in all the speci- 

 mens we have examined they have two spines. 



Diphaglossa Gayi, Spinola, the type of the genus, is described as 

 black, with a long-haired red abdomen, and Dr. Friese notes that it 

 resembles in habitus the red-haired Bombrts pascuorum. The wings are 

 thickly set with fine short hairs.
