3G() Mr. T. D. A. CockewW— Descriptions and 



of scutcllum sliininu;. irregularly sparsely [mnetui'cd ; area of 

 mctatliorax sharply bordered and covered with excecdinj^ly 

 tine striic ; tegulie shining rul'o-piceous. \\'ings a little 

 dnsky, iridcseint ; stigma rcd-l)ro\vu, nervurcs fnscoiis ; 

 venation essentially as in H. margbiutiis, but the stigma is 

 larger and the marginal cell somevvhat shorter. Legs 

 black ; abdomen shining, the hind margins of the segments 

 broadly ruio-tcstateoiis ; there are bas:d white hair-bands 

 and the hair ot apex is ])alc sooty. 



Easily known from H. jnan/inatus by the shorter strongly 

 margined area of ractathorax, mueh darker stigma, &c. 

 From H. virgatiis it is known by the much finer striae of the 

 area of metathorax, much less coarsely sculptured abdomen, 

 and colour of hair of apical segment; it is also somewhat 

 smaller and the abdomen is narrower. From H. Jiinbriatus 

 it ditiers in the colour of antenna?, shape of abdomen, &c. 

 Last ventral segment with no longitudinal keel, but penulti- 

 mate one with a transverse ridge. 



Hub. JMcsilla Park, New Mexico, April 30, 1900, at flowers 

 of Fallugia acuminata (Wooton) ; two [Cockerell). 



Ctenoplectra cJiahjbea, Smith. 



In Ann. & Mag. Nat. Hist., Sept. 1904, I described 

 6'. vagans from the Philippine Islands, separating it from a 

 specimen of C. chalybea, ostensibly the type, from Celebes. 

 1 now find,howe\er, that the real original type of C. chalybea 

 was collected by Wallace at Mt. Ophir, Malacca, and is 

 j)resumal)ly in the Hope jMuseum at Oxford. I cannut tell 

 liom the description whether the j\Ialacca insect is identical 

 ■with the Celebes or the Philippine one, or different from 

 both ; but since Smith considered it to be the same as that 

 fiom Celebes, we must so assume for the present. 



Melissodes hortivagans, Ckll. 



Fedor, Texas, May 29, June 7 [Birhmann). 



NcAV to Texas. One female is a partial gynandromorph, 

 having the right side of the clypeus and labrum liiiht lemon- 

 yellow, while the other side is black, the colours sharply and 

 evenly separated.
