MOTHS OF THE GENUS RHABDATOMIS — FIELD 55 



segments underneath, which are fuscous. Forewing above very 

 similar to R. laudamia, with parallel fuscous fasciae separated by 

 slightly more distinct yellow line. Forewing below as in laudamia. 

 Hindwing on both sm-faces with costal margin and apical half of outer 

 margin fuscous, thus differing from lauda7nia which has basal half of 

 costal margin straw yellow. 



Length of forewing 11-12.5 mm. (average, 11.6 mm.). 



Male genitalia as characterized in key and as illustrated by figm-e 5. 

 See remai'ks under R. laudamia. 



Female. — Unknown. 



Type locality. — Tuis, Province of Cartago, Costa Rica. 



Additional type data. — Described from holotype, male (Aug. 

 28, 1908; USNM type 34856; Schaus Collection; cf genitalia slide 

 WDF 1318), from five male paratypes (same locality as holotype; 

 Sept. 1, 1908, Aug. 29, 31, 1908; Schaus Collection), and a sixth male 

 paratype (Cartago, Costa Rica; cf genitalia slide WDF 1558; Schaus 

 Collection). 



Location of type. — United States National Museum. 



Distribution and material studied. — This species is known 

 solely from the holotype and paratypes listed above. 



Remarks.— Species named for Dr. Max Draudt.

Figures 7, 24 



Male. — Figm-e 24. Head and thorax as in R. laudamia and 

 R. draudti. Abdomen entu^ely straw yellow except for lateral oblong 

 patches of fuscous on segments 3 and 4. Both forewing and hindwing, 

 above and below, entirely like laudamia. 



Length of forewing 9.5-10.5 mm. 



Male genitalia as characterized in key and as illustrated by figure 7 

 differs from all other species in genus in form of harpe, aedeagus, and 

 juxta. Hai'pe has apical lobe from costa sharply curved inward and 

 cuiller slightly curved downward. Juxta has sharp spinelike pro- 

 jection from posterior margin. Aedeagus has distal lobe projecting 

 from middle of left lateral sm'face. 



Female. — Unknown. 



Type locality. — Cordoba, State of Vera Cruz, Mexico. 



Additional type data. — Described from holotype, male (Jan. 

 5, 1908; USNM Type 34857; Frederick Knab, collector; cT genitalia 

 slide WDF 1550), and from one paratype, male (locality as given for 

 holotype; Feb. 8, 1908; Frederick Knab, collector; <^ genitalia slide 

 WDF 1549). 



Location of type. — United States National Museum.
