Anthidium matucanense new species. 



Male. — Length about 12 mm.; black, with long hair; clypeus, cuneiform 

 marks filling space between clypeus and eye, greater part of outer face of 

 mandibles, and small spot above each eye pale yellow (primrose yellow) ; 

 antennae black, flagellum very obscurely reddish beneath ; thorax and legs 

 wholly without light tegumentary markings ; mesothorax very densely punc- 

 tured ; tegulae black; wings dilute fuliginous; hair of head mainly white (long 

 and snow-white on clypeus), but strongly mixed with black on front, cheeks 

 anteriorly and above, and vertex, all black in region of ocelli ; hair of thorax 

 greyish-white mixed with longer black hairs, on ventral surface wholly pale ; 

 hair of abdomen greyish-white at base, but largely mixed with black on second 

 segment, and beyond that black ; femora with black hair ; anterior and middle 

 tibiae with black hair on outer side, and long shining white hair behind ; hind 

 tibire black-haired, with short dark brown hair on inner side and a patch of 

 appressed white hair at apex above; tarsi with white hair on outer side and 

 dark reddish on inner ; first five abdominal segments each with four pale 

 yellow spots, sixth with two spots, apex without spots ; lateral spots on first 

 three segments large, more or less excavated on inner side, those on fifth 

 reduced to minute dots ; apex tridentate, the middle tooth slender, the lateral 

 ones taking the form of broad lobes, with convex, outer margins. 



Habitat. — Matucana, Peru, June-July, 1913 (Bnies). 



Yery close to A. garlcppi Schrottky, from Apurimac. Alatucana 

 is about 50 miles inland from Lima; Apurimac is about 250 miles 

 southeast from Matucana, on the other side of the mountains. It is 

 possible that the species now described should be regarded as a sub- 

 species of garlcppi, but it differs in the abundant black hair. These 

 insects belong to typical AntJiidiiiiii. 



Triepeolus megadelphus new species. 



Male. — Length a little over 11 mm.; black, mandibles dark red except at 

 apex, antennae black ; legs bright ferruginous, middle tibiae with a blackish 

 stain on outer side, greater part of hind tibiae blackish, hind femora black 

 beneath except at base and apex, and largely black at sides ; tubercles and 

 tegulae bright ferruginous ; wings dilute fuscous ; hair-patches of body cream- 

 color, mesothorax with two straight bars, not swollen at end ; abdomen with 

 interrupted bands, entire or almost so on fifth and sixth segments, black area 

 on first segment acutely angulate at sides ; fringes on fourth and fifth ventral 

 segments creamy white. Clypeus densely rugoso-punctate ; pleura closely and 

 strongly punctured, its lower part bare or almost, its upper part with pale 

 greyish hair, in the middle of which is a bare space ; spurs rufopiccous. 



Habitat. — fluayaquil, ]\Iay-June, 1913 (Dnics). 

 \^ery close to T. biichwahii (Friese), and marked in a similar 

 manner, but larger, the markings much paler (less yellow), the head
