SYSTEMATIC ACCOUNT. 53 



and one from Eritrea (Africa). I am unable to agree with him as to the advisability of 

 separating Curtonotum and Diplocentra. The character given (number and distribution of 

 sternopleurals) seems too trivial and variable to furnish a natural or convenient generic 

 separation. Even if the separation is accepted, the use of Diplocentra as a name is not 

 correct. Since it was proposed as a change of name for Curtonotum (because of a sup- 

 posed preoccupation) it must necessarily have the same type species — and under no cir- 

 cumstances can both names be vahd. Enderlein makes his new species lumidum the type 

 of Curtonotum, on the grounds that it was the form seen by Macquart, who identified it 

 as Musca gibba Fabricius. I am unable to agree with the contention that this invaUdates 

 gibba as the type species. 



Enderlein assigns the group to the " Ephydridse," as a separate subfamily. This 

 treatment has certain points in its favor, and may be accepted or not, according to per- 

 sonal preferences. 



Apsinota van der Wulp. 1887. Tijd. v. Ent., 30, 178. 



This genus was described by van der Wulp as a geomyzid, and was also 

 referred to that group by de Meijere. Van der Wulp, however, states that 

 the genus is near Diplocentra {— Curtonotum), and that genus has been 

 referred to the Geomyzinse by Loew, Osten Sacken, and others. Until 

 data with regard to the costal breaks and other characters are available, 

 it seems best to place Apsinota among the Drosophilinae, next to Curtonotum. 



Like Curtonotum, it differs from typical Drosophilinae in having a well-developed auxiUary 

 vein. It also agrees with that genus in having a plumose arista, prescutellars present, 

 bristlSy mesopleurse, preapicals on all tibiae, discal and second basal cells confluent, and 

 strongly convex mesonotum. It differs from Curtonotum in having small postverticals, 

 large carina, costa not pectinate, only one (reclinate) large orbital, and no large vibrissse. 

 The last two characters are aberrant in the subfamily. 



Two species have been described: A. pictiventris van der Wulp, the type 

 of the genus, from Java (van der Wulp and de Meijere) and New Guinea 

 (Kert^sz), and A. ohscuripes de Meijere, from Java. 



Thaumastophila Hendel (1914, Suppl. ent., 3, 112) differs from Apsinota 

 in that the front of the male is very much narrowed. The posterior scutellar 

 bristles are divergent, which is apparently not the case in the described 

 species of Apsinota. The only known species is T. hyalipennis Hendel, 

 from Formosa. In the key to genera (p. 50) and in the discussion of 

 distribution (p. 115) I have included this form under Apsinota. Further 

 study may warrant its separation. 



Titanochaeta Knab. 1914. Insec. Inscit. Menstr., 2, 168. 



This genus suggests the Ephydrinse in that it has a pectinate arista; flattened, weakly 

 carinate face; head and thorax pruinose. It has, however, well-developed anal cell and 

 vein, and large vibrissas, so is perhaps most conveniently left here. It also has the following 

 characters: three orbitals, disposed as usual; postverticals long, crossed; ocellars large; 

 eyes hairy; no prescutellars; two notopleurals ; two large dorsocentrals ; two pairs of 

 Bcutellars, posterior ones crossed; two sternopleurals; preapicals on all tibiae, apicals on 

 second; auxiliary vein rudimentary; costa to tip of fourth vein. 



The only described species is Titanochceta ichneumon Knab, from Hawaii. 

 The specimens were reared from spider eggs. I have examined the types. 



Cladochaeta Coquillett. 1900. Proc. U. S. Nat. Mus., 22, 263. 



Arista with a single long branch above; second orbital minute, a hair between upper 

 orbital and vertex; ocellars present; postverticals small, convergent; one vibrissa; one 

 humeral; one presutural; two notopleurals; two supra-alars; two postalars; two dorso- 

 centrals; two pairs of scutellars; no prescutellars; acrostichal hairs in six rows; one sterno- 

 pleural; no propleural; apical and preapical bristles on first and second tibiae, preapicals 

 on third; eyes bare.
