of the clypeus projects outwardly and is sliglitly incised in 

 the centre; the two longitudinal furrows on the basal half 

 of the mesouotura are indistinct ; there is a narrow keel on 

 front extending from the front ocellus to the antenuce. The 

 keels on tlie median segment are very irregular and more or 

 less broken or disconnected ; there is no central depression ; 

 the third joint of the antennae is about one-third longer than 

 the fourth. There is no clearly defined area on the base of 

 the median segment. The si)ecies is allied to P. orientidis 

 and P. reticulatus. 



T'achytes andreniformis, sp, n. 



Nigra, capite thoraceque dense aureo pilosis ; pedibus rufis, coxis, 

 trochanteribus basique femorum nigris ; alis flavo-hyalinis, apice 

 fere fumatis ; cellula cubitali 2-' duplo longiore quam V\ 2 • 



Long. 17 mm. 



Scape of antennae brownish beneath, sparsely covered with 

 long fuscous hair ; the flagellum thickly covered w ith a pale 

 down. Vertex covered with long fuscous hair, which does 

 not hide the skin ; the front, face, and clypeus thickly 

 covered with longish bright golden hair, hiding completely 

 the texture. Base of mandibles covered with pale golden 

 pile, the middle is rufous ; palpi bright rufo-testaceous. 

 Thorax covered all over witli bright fulvous hair ; the texture 

 under the hair is granular. On the mesosternum behind the 

 transverse keel is a narrower longitudinal one ; the meta- 

 sternal area has a narrow keel, narrowed in the middle down 

 the centre, the apex is depressed and rounded. Legs bright 

 rufous, the eoxse, trochanters, and sometimes the base of 

 femora, black ; the tibial and tarsal spines are rufous. 

 A\ ings distinctly yelloAvish hyaline; the nervures rufous, 

 the apex slightly infuscated ; at the top the first cubital 

 cellule is equal in length to one-third the length of the 

 second ; the first transverse cubital nervure is obliquely 

 curved above the lower fourth ; the second recurrent nervure 

 is received shortly beyond the middle of the cellule. Abdo- 

 men black, shining, the basal segment thickly covered Avith 

 fuscous hair ; the hypopygiura is thickly covered with bright 

 fiery-red pubescence ; the epipygium is distinctly incised on 

 the apex, the sides of the incision are somewhat oblique. 

 The second recurrent nervure is roundly curved, not angled 

 anywhere. 



Agrees in form and coloration with T. fuIvojA/osa, which 

 may be known from it by the first cubital cellule being not
