eyes but slightly convergent, the space between them on the verte.^ 

 being unusually wide ; antenuai slender, unusually long, extending to 

 the base of the abdomen ; median portion of the clypeus broadly pro- 

 duced, armed with two teeth on each side ; the labrum concealed ; man- 

 dibles long, very sHghtly dentate near the base within. Head and 

 thorax closely punctured, opake ; the anterior portion of the clypeus 

 with larger punctures intermixed ; anterior ocellus in a pit, fi'om which 

 an impressed line extends to the insertion of the antennoB ; posterior 

 ocelli obliquely distorted, an angular depression behind them connected 

 with the depressions on each side. Mesothorax with four short impressed 

 lines anteriorly, a longitudinal impressed line on scutellum and disk 

 of metathorax, disk of metathorax finely striated transversely, the pos- 

 terior face with a deep elongated pit above, from which an impressed 

 line extends to the insertion of the abdomen. The median joints of the 

 anterior tarsi narrowing rapidly towards their base ; the anterior tarsi 

 armed with short stout spines externally, there being six spines on the 

 basal jomt and two at the apex of the following joints externally, eacli 

 spine as long as the third tarsal joint. Margins of the abdominal seg- 

 ments shining, apical segments clothed with an appressed golden pubes- 

 cence, area on the sixth segment sharply defined, strongly i)unctured. 

 Allied to L. cetliiops (Cress.). 



MONEDULA EMAKGrlNATA CreSS., S. 



The four anterior tarsi with slight spines at the tips of the joints. 

 Intermediate femora not serrate beneath, or with only the indication of 

 a tooth near the knee. Basal joint of intermediate tarsi slightly curved 

 and with a row of four or five slender spines near the base beneath. 

 Abdomen slightly pubescent, the disk of the second ventral segment 

 with a tubercle on each side of the median line. The apical segment of 

 the venter bearing the four stout teeth is the eighth ; the lateral teeth 

 nearly straight. 



COLLETES CILIATA n. sp., 5 . 



Length 8""". Eobust ; black, tips of the mandibles and tarsi rufo- 

 piceous, flagellum piceous beneath. The pubescence pale ochraceous, 

 the segments of the abdomen with an even fascia of ai)pressed pubes- 

 cence. Space between the eyes and mandibles unusually short; clypeus 

 coarsely punctured, the punctures running into rugae, an abbreviated 

 transverse depression just before the tip ; labrum with several irregular 

 longitudinal depressions at the base. Sides of the prothorax angulated, 

 not prominent. Disk of the thorax shining, finely and si)arsely punc- 

 tured, a spot in the centre without punctures. Base of the metathorax 

 irregularly reticulated, the sides closely punctured. Anterior coxse 

 unarmed, all the tarsi ciliated with long hairs, the tarsal claics deft, the 

 inner tooth almost equalling the claw. (In this species, as in C. aestivalis 

 mihi, the cleft claws of the female have the prongs more divergent than
