AMMOPHILA. 9 



Antennae almost bare, or slightly hoary. Head covered with long blackish hair, 

 punctured, but not strongly ; frontal furrow wide, shallow. Clypeus transverse at the 

 apex ; the angles obliquely rounded, scarcely projecting. Third antennal joint twice 

 the length of the fourth. Thorax opaque, covered with shorter and paler hair than 

 the head, closely punctured ; the furrow on the mesonotum deep, wide ; a narrow 

 furrow runs down from the tegulae, and a short transverse one runs from it opposite 

 the tubercles, uniting to an oblique one ; mesosternal furrow distinct ; metanotum 

 closely, transversely striated, scarcely depressed in the centre. Abdomen covered with 

 a close hoary pile ; the apical three fourths of the second and the third and fourth 

 segments entirely red. The petiole has scarcely a bluish tinge. Tibiae and tarsi 

 covered with a hoary pile, the latter densely spinose, the former with a few stout 

 spines. The second cubital cellule is longer on the upper and lower side than the third, 

 the top half the length of the bottom, the latter slightly angled where the recurrent 

 nervures are received — before the middle and a little before the apex; the third 

 cellule at the top is about one third of the length of the bottom ; the third transverse 

 cubital nervure is turned backwards before the middle is reached. 



2. Wings fuscous ; thorax densely pilose. (Species 10-25.) 

 f Mesothorax striated. (Species 10, 11.)

Nigra, thorace capiteque dense griseo-pilosis ; thorace fortiter punctato, supra transverse* striolato ;. scutello 



longitudinaliter striolato ; abdominis segmentis 2° et 3° pro parte runs ; alis fusco-violaceis. $ .

Hab. Guatemala, San Geronimo and Cubulco in Vera Paz (Champion). 



Head covered with long blackish hair ; the front and vertex finely, the clypeus more 

 strongly, punctured ; front depressed above the antennae* and with an indistinct furrow 

 running down its middle ; clypeus transverse in the centre. Third antennal joint more 

 than twice the length of the fourth. Thorax densely covered with longish (but still 

 shorter than that on the head) grey hair ; the pleura? strongly punctured, the tubercles 

 impunctate ; pro-, meso-, and metanotum strongly transversely striolated, except the 

 mesonotum at the base; scutellum strongly longitudinally striolated; postscutellum 

 rugose ; there is a narrow furrow in the centre of the mesonotum, and a narrow, not very 

 distinct, furrow runs down from either side of the tegulae. Coxae and femora sparsely 

 covered with long black hair ; tarsi densely, the tibiae sparsely, spinose. The top of 

 the second cubital cellule is a little longer than the space bounded by the first trans- 

 verse cubital and the first recurrent nervures ; the latter is received before the middle ; 

 the third cubital cellule is somewhat longer than the space enclosed by the two 

 recurrent nervures and about one fourth shorter than the bottom of the cellule.
