minute black spot beneath, the posterior pair black, all the femora 

 and tarsi rufous : abdomen rufous, black at the base, with two waved 

 cream-coloured lines on the first segment placed laterally, the second 

 has two wedge-shaped white spots, the third two smaller, the rest are 

 very obscurely maculated laterally : the abdomen is immaculate 

 beneath. This is an autumnal species ; it appears in August. I have 

 captured it at Weybridge, Surrey, and also at Hawley, Hants.* 



Sp. 21. Nomada inquilina, Smith. 



Length 4| to 5 lines. Female. Head black, margin of the clypeus, 

 the labrum, mandibles and a spot at the apex of the eyes, rufous ; 

 antenna? beneath, the apex of the joints above, and the extreme base 

 and apex of the scape, rufous, the third joint sometimes entirely so ; 

 a minute tooth on the labrum : thorax black ; the tegulae, tubercles, 

 and two spots (generally united) on the scutellum, rufous : all the 

 coxae and femora black, rufous at their extreme apex ; all the tibiae 

 rufous, the anterior pair with a black spot behind : abdomen, the first 

 segment black, with a transverse rufous fascia, the second has large 

 lateral yellow maculae, acute within, sometimes united, or but subin- 

 terrupted, the third and fourth have narrow yellow fasciae, and the 

 fifth a square yellow patch, the apical margins of the segments are 

 dark rufo-piceous ; beneath, the first segment black, the rest rufous, 

 the margins dark rufo-piceous, in rare instances there are two or more 

 yellow fasciae. 



Male. Head black ; margin of the clypeus, labrum and base of 

 the mandibles yellow, their tips rufous ; scape of the antennae black, 

 the remaining joints rufo-piceous beneath : the thorax black, tuber- 

 cles and tegulae rufous : legs as in the female : the face, cheeks, coxae 

 and femora, with a dense palish yellow pubescence : abdomen, first 

 segment black, with a rufous fascia, the second with large lateral yel- 

 low maculae, acute within, the third, fourth, fifth and sixth with yel- 

 low fasciae, the apical margins broadly rufo-piceous ; beneath, the first 

 segment black, the rest with indistinct rufous fasciae, more or less va- 

 riegated with abbreviated yellow fasciae. 



This species somewhat resembles some of the dark varieties of rufi- 

 cornis, but is very distinct : its black thorax and scape easily separate 

 them; the abdomen also is much broader than that of ruficornis. 

 This insect was taken by Mr. Newman, some years ago, at Leomin- 

 ster, in Herefordshire. He fortunately captured a series of specimens,
